what about if i am studying for a physical instructor course exam? what would your suggestions be on me researching more?
This is by far the most efficient and simple explanation I've seen on bioenergetics related to the NASM program. Thank you so much, I'm currently cramming for my exam in one month!
Robot Kittyyy! Except his Krebs cycle diagram, is wrong! He is too over simplifiying it and it is wrong.
THIS IS LITERALLY SO HELPFUL, its the best way of explaining everything in detail but also in a short way
The way you explained the whole process is just amazing. I was struggling so much. Thank you! 💕
I am gonna take CSCS exam next month, i must tell you i was having a hard time getting clarity about glycolysis but your explanation nailed it ! Thank you for sharing it. God bless you bro 👍
Glad it helped! Make sure you join the Facebook group: facebook.com/groups/2415992685342170/
I already did that moment !
WOW! I feel like a boss right now. This material can be overwhelming, yet this breakdown has allowed me to see the light. You have shown me the way like David Goggins has. I wish you exponential success!! I appreciate you!!
Wow I’m going to call myself the David Goggins of bioenergetics now
Thank you so much for the great explanation/breakdown! ✨
om gosh you are so helpful--great concise explanation--plus super easy on the eyes
I'm going through nasm for my cpt. I just now started learning this stuff and was soooo confused! This helps me out so much! Thank you!
Glad it was helpful for you!
Same... I’m doing NSCA
This completely simplified the topic for me! Thank you for sharing!
You're welcome
This was explained so well and was much easier to understand than my lecturer's powerpoint. Thank you so much!!
You're welcome
Nice video overall, but there’s a mistake. When pyruvate is decarboxylated into acetylCoA, there is no O2 coming in to bind to C and form CO2. The CO2, i.e. COO, is simply the carboxylic function (COOH) that came from the pyruvate. However you didn’t mention the CoA that comes in at that step to form acetylCoA. O2 only comes into play at the end of the electron transport chain.
Thank you
thanks so much for the clear explanation, you just got a new subscriber! your videos are cool !
Appreciate it!
THAT REALLY HELPED ME. WOW, GREAT JOB.
Wonderful simplified explanation 👏 thanks
Thank you for this! You're really helping me with my NSCA studying!
Happy to help!
Helping me as always. Thanks alot
Very much useful. Explanation and providing attention by deeply pronouncing few terms was really good 👍 Thank you
Great glad it was helpful for you
Hey Matt!! I’m currently studying for Nasm-cpt certification and this video helped me out a lot thank you!
Best of luck!
Thanks for this... I understand this completely now
You're a very good teacher!
This was the best explanation!
You made this super easy! Thank you so much! :D
You're welcome!
Man, Im doing my PT cert right now and wow.. thank you so much for being able to lay all this out. The text I have is really hard to digest compared to your explanation. Really man, thanks.
I'm doing mine right now, this was good.
Wow, thanks so much. Well explained
THANKS MAN! I really like this. Very helpful
You're welcome!
Thanks for sharing
Thank you so much! Simply put!
Thanks for watching!
Very well explained! Thanks!
You're welcome
Thank you! This was awesome.
You're welcome
So helpful! Thanks!
You're welcome!
Easy demonstration. Thank you
You're welcome
Awesome!
the best explanation vedio i have ever seen...thankyou so much sirr🫠🫠🫠❤️🔥❤️🔥
That was fantastic man 👌
Thank you!
Very nice...👌
THANK YOU!!!!
Good topic exlanation
thanks
Have my University entrance exam in two days... No one has taught Kreb's cycle this smoothly ever to me.. This video was really useful.. Thank you 🙏
Wishing you the best on your exam
@@TheMovementSystem Thank you so much 😍
very helpful and easy to follow
Glad it was helpful!
Very nice its so easy now .. thanks
Great! You're welcome
a better teacher than my professor!
Thank you ❤️
You're welcome!
I MISS THE NORMAL DAYS. I DON'T LIKE DOING DISCUSSIONS ONLINE, BUT WATCHING YOUR VIDEOS MOTIVATES ME.
Glad they are helping you!
Bro! You're goood!
Isn't the first part of the Krebs cycle known as the Links reaction ? Thank you for your explanation!!! it was super helpful
Hey Matt! Are you a wizard? Just watched your vids lately and I was thinking to myself "maybe you should ask him to make a bioenergetics vid". lol thank you so much! :)
You're welcome! Glad it helped!
1st year med student here, this video is GREAT!!!!!!!!!!
Thanks!
Do questions on something like this require absolute recall of all these molecules and complete process or just being familiar with it at a higher level?
I'm confused. My textbook says that a net yield of 32 ATP is given "from energy transfer during the complete oxidation of one glucose molecule in glycolysis, the citric acid cycle, and electron transport."
What am I missing here?
Can't see the forest for the trees are blocking my sight. So what is good or bad and what should we do about it.
How many ATP does aerobic and anaerobic respiration produce?
So you get 2 NADH from aerobic glycolsis. 2 NADH x 3 = 6 ATP. If it costs 2 then shouldn't the NET be 4?
can you please explain why you are multipling the 10 nadh by three ? and 2 fadhd by 2 ?
When those substrates are oxidized in oxidative phosphorylation that’s how many ATP they produce
form 4:30 onwards i just became completely lost. I dont understand the NADH bit and how it correlates to the krebs cycle. And the atp part, 2 extras form glycolysis amd the timsing by 3 to make 30 atp doesnt make sense to me either. Can someone recommems a video to help break this part down. tyy :)
just watched ur other video breaking it down and i understand it a bit better now thankyou :D
Hey man, just want you to know
THIS WAS A GOOD VIDEO
Probably can always get better but this was very good and I’m here totally randomly and a huge critic lol
In case it helps to know; I Randomly found this searching up “bio energy” which is some jokey new age health nut shit I watched “Philion” make fun of
i dont see where the 4 NADHs are in the end of the krebs cycle
Is the electron chain transport a part of this?
That’s another name for oxidative phosphorylation
👍🏻👍🏻👍🏻
Anyone want to check my work?
For a 16 chain fatty acid you will make 129ATP.
Is that correct?
Can u explain me about what happens if there are more pfk..?
Glycolysis goes faster. More ATP
@@TheMovementSystem thank u..
@@varunjirali9272 You're welcome
Waiting for ur videos.. so easy to learn..
Same for lypolisis pls?
Here’s my video lipolysis vs. beta oxidation: m.ua-cam.com/video/0EUslLbIkXo/v-deo.html&feature=emb_logo
Very useful video, but everywhere I look it shows that only 32 ATP comes from 1 glucose.
did you mean to say anaerobic glycolysis instead of aerobic glycolysis (because you said the aerobic glycolysis doesn't need O2 but the definition of aerobic says it requires O2 and anaerobic doesn't require O2???
Neither require oxygen actually. These are both done in the cytoplasm without oxygen. Aerobic glycolysis just indicates that once split, the pyruvate will continue on to the mitochondria and use oxygen to break down more in the Krebs cycle. Anaerobic indicates that the pyruvate will turn into lactate.
@@TheMovementSystem Thank you so much for the explanation. That makes so much more sense now!
@@madisonhagen7133 You're welcome!
im a little bit confused. you said that glycolysis doesn't need oxygen. but you wrote above the diagram "aerobic glycolysis" and said that if you didn't have oxygen, you would get lactate.
Yes. The process of glycolysis is occurring in the cytoplasm without oxygen. It's what happens after glycolysis that determines if it's aerobic or anaerobic. So if after glycolysis is done there is room in the mitochondria for the pyruvate to be metabolized the process is considered aerobic glycolysis and the pyruvate moves onto the Krebs cycle. If there is not oxygen in the mitochondria then the pyruvate will turn into lactate. That is termed anaerobic glycolysis. The terminology is confusing because in both cases the process of glycolysis didn't require oxygen.
if I was marking an exam on the Krebs cycle, he had done, if he had written this, I would fail him.
how is 4x2 equaling 10?? Am i misinterpreting a step or something?
What part of the video are you referring to?
The Movement System the end where you multiple 4 by 2 for ATP
@@quon535 I'm still not sure what you mean. It's 34 from Oxidative phosphorylation + 2 from Glycolysis + 2 from Krebs cycle = 38
The Movement System ok you have
4NADH x 2 = 10....
The Movement System ahhhhh never mind.... u explained it at 5:28 mark :))
isnt there 2.5 ATP per NADH not 3?

Except his Krebs cycle diagram, is wrong! He is too over simplifiying it and it is wrong.
He is explaining bioenergetics , not creb cycle
