@joessj5 the fat in your body is stored for later for whenever you need energy. So if you go in starvation mode, your fat will be used as energy after muscle has been used first, thats why fasting is a bad way to lose weight because you lose all the good weight(muscle) first, so you're going to be all flabby lol
"Maybe we have some... Not maybe, this is what happens." Lol but really, great video. Helping me understand & remember this for my biology exam. I'm a Comp Sci major in college, so I have a hard time retaining much about biology.
this helps so much... im a 2nd semester sophomore biology major and this video finally made the krebs cycle click for me, i've taken 4-5 upper level bio classes where the krebs cycle was tested on and now i get it haha so thanks:)
u make me fall in luv with the things i used to hate!!!!.Funny!! :P..now i get it tat u shd not judge the topic by the way they teach in yo class juzt like how you shd not judge a buk by its cover!! :D
glad everyone this found it BEFORE their test... I found it after. lol. Oh if only I just watched this instead of spending 5 hours deciphering the words in my bio textbook. Thanks for these awesome videos
Can anyone help me? When NAD is reduced on the wikipedia diagram he shows at the end, it is shown to form NADH and an H+ ion. Where does this come from? Is it part of the process of reducing NAD? Thanks if you can help!!
i love these vids, my biology teacher showed us one to help us understanding the topic. at that moment he lost my interest in his lessons and my willing to take notes. i'll stick to your vids intead :DD
i can understand it better than what my lecturer taught me.. thanks for making this vid... now i can prepare for my test tomorrow and next week exam.... =)
thank you soo much, evry website said that krebs produced 6 atp, and then said : therefore produced 8, i was like "WHAT?!" but NOW i see that the pyruvates are what they were counting! thank you soo much :D
Great job this really helped... But no ATP is actually produced in the Krebs Cycle. Instead GDP is converted into GTP and the phosphate group in GTP is later transferred to ADP to form ATP.
Haha your videos are perfect for cramming the night before. Thanks man, I've been reviewing the whole cellular respiration process for a while and this is the first time it's really made any sense :)
Thank you so much. It's really working. Easily getting into my mind. Arghh later I no need to refer my textbook again which is much more complicated. thanks again dude.
Wow thank you so much! I covered this in my sophmore level anatomy and physiology class- online and what a great help this clip was =) Once again THANK YOU!!!
I think the reason you are better at teaching than teachers is because you repeat what the terms are and you take your time. Teachers just rush the stuff.
This is a great video, I just want to add that nowdays more biochemists take 2.5 ATP molecules per NADH and 1.5 ATP molecules per NADH2...if you do that calculation the net result will be 32 ATP total
I understand that NAD+ is the oxidized form of NADH, so in other words NADH is the reduced form of NAD+...just saying...FAD is reduced when it becomes FADH2
wow, thank you SO much! I was so enthusiastic about learning biology from khan academy that I just youtubed to see if khan academy had the calc topics I was learning, and it did!!!! I'll definitely be prepared for school tomorrow... wow I have never been this excited about learning.
Awesome video, thx a lot. I think it is really important to look at all these things happening in the cells step by step so it doesn't get to complicated. You are doing a great job teaching these things to a lot of people.
Does anyone knoe where the preparation step takes place? mitochondria matrix/ outer cell-department or outside the mitochondria?
Unfortunately, my professor requests I memorize every structure, byproduct, enzyme, output, of glycolysis, fatty acid metabolism, the pentophosphate pathway, and aminoacid metabolism (as well as reversal - catabolism). I'm so happy for tomorrow (my test). Stroke? Heartattack? MURDER?
I've been taking online college classes (chemistry, anatomy and physiology) for over a year now and I truly think they're better than on-campus classes. Just an opinion based on experience. This instructor sure has my attention and I will be a loyal subscriber.
