ATP: Adenosine Triphosphate

[NisaMaisara]

great share..

[ThaFacka]

Could you use ATP for replacing fossil fuel by efficient (and hopefully simple) synthesis under room temperatures? I don't like all the storage problems H2 gives us.

PS: This is no joke question.

[iCrlyfreek]

These videos are great because my teacher for ap biology does not teach at all.

[fraglepuss]

his videos are just a forum for people to slag of their lecturer's

[SoiGuessImAwesome]

i like his handwriting 

[LiquidFireProd]

If these guys know so much about this topic (comment above), why are they watching these videos? stop giving me nightmares that khan academy makes a mistake.

[MrHoneyloops]

A man walks into a bar and says, ' I'll have have a pint of adenosine triphosphate, please', and the barman says, 'That'll be ATP please'.

[papwalker99]

@MrHoneyloops groan

For the non poms (yanks et al)

Eighty Pee = eighty pence

Took me a while.

[8PAlice]

Wow, wonderful!! I wish you were my teacher as well! Really great, clear, and explained simply :) Thank you!

[acquful]

thanx a lot..........

[Rooseveltboh]

LETS GO!!! BOUTA GET THAT A :)

U FUCKIN ROCK DUDE, I HAD 2 SUBSCRIBE LOL. EVERYONE DO THE SAME

[cullenist]

I love you!

[LiquidFireProd]

@gamingforyou69 go on his channel, n u'll find out

[micahflett]

"Let me do it in a nice colour."

"Ooh. I wonder what colour he'll choose!"

[BigMootsie]

his voice is pleasing to my ear holes.

[PO3TRYFL0W]

@BigMootsie what's a "Mootsie"?

[BigMootsie]

@PO3TRYFL0W whatever you think it is.

[selurhajile]

i am in 9th grade bio, this helped so much. i love learning little tidbits like this. thanks for the lecture

[hpdarkman90]

@selurhajile same haha this guy really helps

[crblack33]

i cant help but to listen over and over how u say "currency"... i love it . creepy, i know.

[Mcdriva123]

WHY ARE THERE DISLIKESSS!!!!!!!!!

[Mcdriva123]

WHY ARE THEIR DISLIKESSS!!!!!!!!!

[SidTheSeamstress]

love you kahn!



[creativsis]

Question;

So adenosine triphosphate is composed of adenosine and 3 phosphate groups.

& adenosone diphosphate is composed of adenosine and 2 phosphate group... & a hydroxyl group? Always?

[fufufuyen]

@creativsis Adenosine diphosphate is only the adenosine and the two phosphate groups. It doesn't include the hydroxyl group when the other phosphate breaks off, but if when breaking off the phosphate takes with it an oxygen (4 oxygens now), the OH would then go to the ADP making it the also the hydroxyl.

[errorXXoperator]

Thank you so much! This finally helped me understand ATP hydrolysis.

[EnigmaHood]

Who knew it could be so simple? Thanks a lot, I'm not even taking bio anymore, but it's fascinating to learn about these things.

[Nutsosteel]

Dude never stop making these, You're bettering the world. Please keep going with science stuff, It's the most important! us anatomy and biology majors need you!

[BaseAndAcid]

Your amazing, man. I wish you all the best.

[Shelbatron1000]

Thank you!!! I'm preparing for my biology test this week. Bring it on! lol

[TheMikaela1992]

dude, you're a life saver,

thank you so freakin much.........

[SA3PAZ]

thanks Sooooooooooooo Much :)

[germancanadianboy]

haha i learned this in class :D. still awesome bro...

[loxspliff1]

you have hella good computer penmanship... holy christ fuck

[raptorsmokes0521]

This video just described my love life.

[cwaddle]

Brilliant mate - wanted an explanation of the concep and i got it.

[MrEksaben]

What two losers disliked this? XD

[germancanadianboy]

@MrEksaben i think the losers were like... ??????... and were jealous that others understood it XD

[dylpickles76]

Finally, someone who can put all this together to make some sort of sense! Thank You!!!

[godsownphilosopher]

Just a clarification:

The energy is not released when the bond is broken. From the perspective of physical chemistry, energy is released only when bonds are formed. In the case of ATP, simply cleaving ATP is actually an energy investment - energy is only gained when the third phosphate becomes attached to another molecule. As an example, the free P may causes changes to the shape of an enzyme, which, in attaining a more energetic form, may facilitate the otherwise hefty amino-tRNA synthesis.

[felixthemaster1]

@godsownphilosopher nope

[CarlSagan6]

@godsownphilosopher how is it that energy is released when bonds are formed? I can understand that it "costs" energy to cleave (good word, btw) a phosphate from its "comfortable configuration" (as a physicist, I might use the phrase "least potential state"), but it's hard for me to picture a release of energy upon bonding. What form does it take? Sorry for my lack of knowledge in physical chemistry :)

[DiamondGirlLisaLove]

you make it so easy to understand,, i get it!!!!!!

[kitty45]

you make it so simp[le, i love you D:

[lonesomexheartbrokn]

the smartest man alive

[EvilEyEbRoWzz]

Hey, what does a muscle contraction cost? 80p...

[MegaGeekie1]

Thank you so much for dedicating your time to all of us. We love you!!!!!!!!!!!!

[wendylii]

Great. My teacher used so many lessons to explain it.

[gregorybrtn]

I wish you were my professor. This really helped.

[TNTlovesmusic2011]

Thanks for sharing! This video helped me with my biology class! :)

[brazil004]

You are way better at explaining things then my current professor, I subscribe, please keep these vids comin!

[JRfaust87]

Can't thank you enough. My Human Biology Professor is from Nigeria and has a very thick accent and reading the book can only do so much! Khan, you are my hero!

[Catatonyx]

Thanks for helping with my extension science assignment. How do I cite this video?

[trukambo]

i wish you were my teacher.

[astraeaxoxo]

you saved my life. literally.

[ipwnnoobsable]

there is a special place in my heart 4 u, thanks bra. no homo BTW YOU ARE A SAINT!!!!!!

[duderdo]

You are god.

[bigvalona]

wats the program yur using



[sondinb]

your comment about taking it as a leap of faith really stuck me. I hated biochem for the main reason that i had to take everything in it as a leap of faith, and i didnt appreciate memorizing it. Thanks to your video i can finally understand it and not just memorize it and say it just happens. Thank you so so so much

[Steve7x]

u legend,u made it seem so easy,thanks a million u been a massive help :)

[MissTinkJordan]

What happens when 2 doses of adenosine 6mg and 12mg are non responsive?

[Dabdulla001]

I wish my bio teacher explains bio like you do! I wouldn't be struggling so much =\

great job, very helpful!

[superGoodjuju]

Khan, I looooove your videos!!!! YOU ARE AN AWESOME TEACHER!!!!

THANK YOU!

[jennijenjen9]

ahhaa like the handwriting, the smooth lines, the colors compared to the other videos. xD and even more, SAL!! LOL. THANKS FOR THE VIDEOS!

[itwaskidneyinfection]

so far, i have learned more watching twenty minutes of your videos than my bio teacher taught me in three months. thankyouthankuouthankyou

[smalljerjer]

@itwaskidneyinfection are you morgan? im milton

[BayAreaElite2010]

@itwaskidneyinfection I completely agree!!!! I wish I had come across these videos a long long time ago. My biology professor is a horrible lecturer and I become more confused trying to listen to him. I love your videos here!

[rieanlobo]

nice explanations,.=)

[thejacobo11]

4:08 lol a circle with an A around it :D a little mistake there

[xbj199498007]

thank you sooooo much!!! you will save my life tomorrow! i have bio test tomorrow~~~

[SumySUB]

you are a saver :)

[dudecoolname]

whats a trosphate!??!?!

[gumpgirl1]

i love your writing

[down4good]

Love this vid... Keep on goin!! Very very helpful

[777player]

isnt adenosine, adenine + ribose?

[ctkt21]

@777player yes

[Pocket295]

THANK YOU SO MUCH! YOU HAVE REALLY HELPED ME UNDERSTAND THIS FOR MY ZOOLOGY COURSE! Brilliant! Thank you!!!!!!!!

[disxassociative]

"i could have generated a lot of energy falling to my couch...but i don't know...my analogies always break down at some point..."

hahaha love it

[occupiedusername]

Thumbs up if you think the creator of these should receive the Nobel Prize.

[LexPhilogus]

@occupiedusername If it had an educator's prize, yeah.

[breathebliss]

@occupiedusername Doi.

[RareEmerauld86]

Khan Academy is AWESOME!!!!

[lurkern]

Thank you! you are a real blessing <3

[kidoge]

Thank you... So helpfull cheers guys

[kayesee1]

You are my hero.

[yoyoloto]

this a must see for term finals haha

[gabbcadiz]

2 dislikers didn't understand the video.

[jolsteiner]

Khan, you are my teacher in Youtube University.

[whophead007]

I always look up youtube video's to explain the shit my Biology teacher couldn't explain in a week. This video was very useful. Thank you for sharing this with us. :)

[NERFgunWARLORD]

you know whats funny>?

if someone walked in on him and saw him talking to himself while he wrote all this down....

[lezzles11]

i love your handwriting

[autoCasino]

Very useful. Thanks man!

[purplepick1]

ooo this links what im learning in chem (quantum energy) to bio!!

[JamaicanQween]

You are so GREAT!!!

[ScandyBella]

What about the ribose on the ATP?

[oAkieao]

does the water molecule only react with the phosphate and did not bring the product?( to become one of the product?)

[StylexSai]

I can tell this guy is trying to teach us "visually".

Which is a great thing when he draws out,

and explains everything.

I would ace this dude's class if he was my teacher. :)

[Disinf3ctant]

You deserve to be given a million dollars and a villa on the beach.

[youtindia]

cannot understand on thing at 03:22 that when then it was a-p-p-p + h2o ---> a-p-p + p + energy how could energy come here as the leftover is h2o

[gabe0100]

thank you!!

[tooflyinnit]

Most talented teacher !

[CarlRozario]

@khanacademy During Hydrolysis the O-H bond in the water molecule breaks, so wouldn't that need energy...

Will the P-O bond break symmetrically (7:00)...

[crismesa]

Whaat 13 mins done already? damm u made it feel like 2 mins ur the best!

[trelozombie]

great job!!!!

[captfalconXX]

Awesome work ! I think all biochemistry teachers should see these videos before they get out there to teaching. This is how explanation should be and not to confuse students or try to make the subject even harder.

[XboxTheBeatboxer]

This was exactly what I wanted to hear. Kudos.

[vegeboxme]

I'm doing long distance study using a text book and your on-line tutes are excellent. Thank you VERY much for your efforts.

[Sconz32]

"My analogies always break down at some point" ha! I guess they all do eventually.

[esotericky]

Good job dude. Goddam video kept me really interested and it was all educational

[arreisortho]

Thanks.

I am studying for my Masters in Metabolic Medicine. This stuff is fundamental, but very valuable.

How can I send you some money?

[lejeudicestsodomie]

OKAY dude

i'm studying in medecine school...

First dude, you are my god-teacher in biology

AND

NOW I want a computer with a touchscreen

[clockstopper01]

this is one of the best biology videos i have ever seen. after countless hours of searching for useless irrelevant information on the internet this video cuts to the chase and explains exactly what ATP is. i am very grateful it is free right now. your videos will be great learning tools in college. THANK YOU!

[DiddleMousetrap]

Thnxx!

I like your videos a lot! U r smart my friend!

This video helps me so much!

Thnx thnx thnnnnnx:)!

[studentoflife01]

So wait, the phosphate that was broken down isn't the energy? SO WHAT IS THIS ENERGY? Is it heat, is it an electron, is it light?

[studentoflife01]

@studentoflife01 I don't fuckin' get it at all.

[TheCherokeeboy]

why are you so smart? my frontal lobe doesnt even worth a water bottle :(

[jeewilliker]

this was a thorough and brilliant explanation. a credit to you good sir!

[abdullahmunir]

Blessings upon you Khan!

[Antement]

Hello!

I translated some american video and one man said that it is illegal .

Can you spaek me about this&

I will be happy THANKS

[PanndaKat]

Your vids are wonderful! Soooo helpful!

I just watch them and I get it, while when I try to learn it from my textbook I won't.

[unintent1onal]

This makes SO much more sense than what we've been learning in class. Thank you!

[vickiormindyb]

That biochemist I used to live with told me that double bonds are extremely stable and very difficult to break.

When I asked if there were triple bonds, he said yes but that they're extremely rare.

[diademonster]

Not entirely true

[farvision]

look up Acetylene!

[aimforcentermass]

As a Chem I student, this video is a little outside of my grasp, but the lesson was certainly useful in understanding the mechanisms by which creatine monohydrate works.

[cacho112605]

Thank YOU SOO MUCH! KEEP POSTING BIO AND CHEM VIDEOS =D YOU ARE THE MAN!

[shootshoot]

welcome back, you were going pretty nuts there for awhile

[nafizkarim]

yea biology!!!!

[vickiormindyb]

Oh. I thought it was the drug invented in the 80's to help cure AIDS.

We learned about it in Paramedic school when studying infectious diseases. It may have been a different letter between the A and P though.

I have an interesting question. How did you learn so much chemistry and biochemistry? Was it your Minor in college?

I learned more about it by living with a molecular biochemist who had a Ph.D. in Molecular Biochemistry.

[TheLivingDinosaur]

You're thinking of AZT (azidothymidine). Like ATP, it also contains a DNA base and sugar (but thymidine not adenosine) but has an azide group (N=N=N) instead of the phosphates. What wasn't mentioned here is that ATP is also used to make DNA (along with TTP, GTP and CTP - remember the DNA bases A,T, G and C?). AZT works by interfering with viral RNA synthesis and so stops HIV from replicating. Unfortunately it also stops DNA replication and so is pretty toxic and had a lot of side effects.

[Rayman304]

This would have been way more helpful to me a month ago! I'll need it for a final in June though... Thanks anyways Sal!

[CarnalDiafragma]

2nd, lol. Very handy video, thanks, just what I need for my biology exam!
