Krebs Cycle

[Ryans1reason]

Sorry, wouldn't 6 molecules of NADH be produced at the end of the Krebs cycle, instead of 8 molecules of NADH?

I thought, during one cycle you get 3 NADH produced, but then during 2 cycles (2 molecules of pyruvate produced from glycolysis) you get 6 NADH...?

[Yidboy4lyfe]

Wish I could have this guy as my tutor, learnt more in this short video than i have in 4 months of physiology, muchh more interesting to listen to

[lolukine5]

wow thx so much i have learned 20x more from you in about 15 mins than i have with around 10-80 min periods with my bio teacher keep going!!!!!

[mishal4234]

its cOOl......



[TheJavaria]

how many CO2 molecules are produced at the end of Kreb's cycle?

[MrKevinSoGood]

@TheJavaria

Well, to be technical, there are 4 CO2 molecules produced at the end of a FULL Kreb's cycle. If you look at any chart, you will only see 2 CO2 molecules in a rotation being produced, however you have to double the amount of CO2 produced because a full KC is two rotations, typically only one is shown for clarity (1 glucose turns into 2 pyruvates: 1 pyruvate used per rotation: 2 rotations for a full Kreb's) Sorry if I lost you, message me if you need any more help...

Best hand motions ever.

[fabiolalopez1]

This guy is the best. Very good job. You are a great teacher. Makes everything so simple to understand.

[rickmurrda]

just a FAD haha hes got jokes!

[Sunny1Tuesdays]

In my books it says plant cells have mesophylls to do respiration?

[MrKevinSoGood]

@Sunny1Tuesdays

Mesophyll is the "waxy" layer you see on plant leaves, it serves to prevent the plant from dehydration. The thylakoid is were the real magic happens!

[Cleggy112]

Wish this guy did videos at degree level!



[MrJoed1211]

This is so great!!!!... I don't understand my teacher on explaining this..

[jujubeanz0502]

I do which he would have gone into all of the enzymes that catalyze the reactions.

[jujubeanz0502]

He is a great teacher very clear and concise. I like the little memory trick with the matrix!

[IIQSPAT]

lol, Keanu Reeves = Krebbs, nice one nerd

[Minnie1799]

WELL EXPLAINED but our teacher does want us to learn every step, EVERY MOLECULE, EVERY ENZYME, NO OF MOLECULES. Welcome to India.

[rubaram12]

Amazing explanation - thank you SO much =)

[CamCon586]

nice pun, "Don't worry it is just a FAD"

[nejioooo1]

pretty nice keep up the good work

i sucked at Biology but now its so easy for me

[nejioooo1]

My Teacher Disliked This Video

[IWALKTHEMOON]

You guys have any teachers that look like this guy? I do.

[awesomedudemdg]

hold down 4 for a nice lil dance

[obiwankenobi78056]

not bad bro

[canihassteak]

i love you

[liajeanne60]

i learned that it produces 6 NADH and 2 FADH2 -- Hmmmm....

[smartaleck05]

@liajeanne60 Same. I think he tied in pyruvate processing, which results in 2 NADH and the citric acid cycle, which results in 6 NADH. 2 FADH2 is also produced in the Krebs cycle, along with 2 GTP or ATP, depending on the the cell.

[Vasudhacool]

he is a great teacher....he has made bio easy to remember n understand.

[bassil1]

everyone hold down 2 on their keyboard for a surprise

[bassil1]

My teacher should just play all of his videos rather than teach the wrong stuff in biology lol. Awesome science guy

[SuperJdawgful]

amazing!!! i actualy get it!!!!! :D

[Sonamyfan92]

Hey...ummm can you be my new biology teacher?

Pretty please with cherries on top?

D':

[MrDanMan1992]

wow well explain thanx sub

[SahrT1]

One of the best lectures I have herd he makes biology easy to understand and his humor is great

[GunnerProductions20]

What I would give to have you as my bio teacher :(

[MrFrag09]

I wish you were my bio teacher :(

[NezaBlazt]

gosh xD i still dont get this xD!! its so hard!

[tqliu]

you should mention the link reaction and Acetyl CoA

because in most cases, products of the link reaction counts as products of the Krebs cycle. During the reaction, 1 CO2 is produced and the CoEnzyme A is attached to the pyruvate or pyruvic acid removing 1 carbon.

[Fieldhockeyluverrrr]

u are the reason im passing bio!

[FristOneStoned]

khrrrumppa, khrrrumppa, to funny ! lol

[TOproFORthis]

Bravo, my teacher said Aerobic respirtation is for animals only, enlighten me on this please!?

[microcooper125]

@TOproFORthis

Aerobic respiration happens in both, animal cells and plant cells. Plant cells synthesize sugars by a process called photo synthesis, and then break down those sugars to form ATP in the process called Respiration, it can either be aerobic or anaerobic (produces significantly less ATP)

[Snatisfaction]

My teacher taught the krebs cycle over a time of 80 minutes. I learned more in this 5 and a half minute video...

[Misseggroll18]

thank you very much so helpful

[Mimis5643]

THAT WAS SO CLEAR THANKS A BUNCH!!!!!!!!!!!!! 

[lifewithjuan]

Why is 8 the net NADH yield of the Krebs Cycle? If each pyruvate molecule produces a net of 3 NADH, and there are 2 pyruvates in a glucose molecule, where do the other 2 NADH come from?

[Markkkkk26]

@lifewithjuan

It actually comes from pyruvate oxidation. Their yields are often lumped together because both occur in the mitochondrial matrix.

[lifewithjuan]

@Markkkkk26 Ohhh! Thaaanks! :D

[causedhope]

@lifewithjuan Did you count the second Krebs cycle..? 1 glucose from glycolysis = 2 Krebs cycle runs

[lifewithjuan]

@causedhope Yeah, I found out thanks to @Markkkkk26 :D

[tomorrownaty]

@lifewithjuan The other 2 NADH come from the transformation of the 2 Pyruvate into Acetyl CoA :)

So that's two NADH from that process, plus the 6 NADH from the Krebs cycle.

[Janna3strada]

this helped me alot

[klove8107]

You're the Fin MAN!!

[joshandkarla]

This is great teaching. Thank you so much

[Mashelz]

Awesome teacher!

[jrvbjrvb]

thank u for this useful teach and information



[n3rdnona]

I want more! Great teaching.

[SuperJdawgful]

@n3rdnona me 222222222



[SBlova805]

"dont worry its just a FAD" lol great video!

[loo1971]

Amazing! What an awesome teacher you are :)

[petechiae21]

Thank you for this video.. Keep it up.. :)

[mizzahsalamo15]

plss keep posting video it really helps thank you :DDD

[Jdiaz102688]

He is good at teaching and is pretty funny.

[MrChristian1004]

Thanks a lot you are a great teacher. I hope more videos in biology.

[zeldagirly22]

this rocks!

[MakeupGuruFanatic]

Great video! Love the memory tricks =) Thanks so much!
