I love that you explained the difference between anaerobic respiration and fermentation. Some sources only talk about fermentation and neglect to explain anaerobic respiration, giving some people the misconception that they are the same thing.
This is a high yield biochem topic on the MCAT and I’ve yet to see a clear and concise video covering the basics until now. Thanks for the years of help!
thank you!!! this helped me really understand the lesson as our teacher has problems with her internet so it sometimes come off choppy. i watched all your photosynthesis and cellular respiration videos! they all helped me so thank you!!!!!
Hello sir, I'm watching your videos regularly......these are very much helpful to me for exam preparation (government job) here in INDIA... Thanks a lot sir.
at 4:50 you say that the switch to lactic acid fermentation provides a brief burst of energy but how exactly? from what i know lactic acid fermentation produces far less ATP than aerobic respiration so where is the extra energy coming from
There are many nutrients in our bloodstream (not just GLUCOSE) which can be used as fuel for our body including but not limited to: amino acids, fatty acids, glucose, etc... But since your body is exhausted to a maximum degree, you're forced to breathe rapidly and intensely, so making fatty acids as source of fuel (Fatty Acid Oxidation) produces more ATP molecules (129 molecules) compared to using just glucose from fermentation (2-4 ATP molecules) or amino acids (through Alanine Aminotransferase) as energy for our muscles. This is also the reason why exercising too much or having fast metabolism makes someone's body much like of an ectomorph type because they need to consume more calories (particularly carbohydrates) in order to catch up with their type of metabolism and also to gain weight with difficulty.
I have a quick question about the lactic acid buildup causing sore muscles: Has it been confirmed to be the culprit? I remember reading a paper a while ago about a test they did on treadmill runners; one test being flat and the other being a downward incline (decline?) The conclusion was that lactic acid buildup was consistent with both tests, but the general consensus was they felt worse after the decline run leading the researchers to the conclusion that it might be a correlation not causation type deal.
Technically it's not the lactic acid itself, but rather the protons that can be released by the lactic acid to make lactate (lactic acid is just lactate plus an additional proton, H+). If you're familiar with acid-base chemistry, pH = -log[H+]. In simpler terms, a higher proton (H+) concentration equals a lower pH, and a more acidic environment. My guess is that lactic acid (more specifically, the protons released by it, and thus, the acidic environment created by it) probably does cause muscle soreness.
@Smattless Both terms are interchangable (at least that's what I was taught). H+ is one proton and one neutron, so yes hydron is the more proper term. At least where I was taught, we simply referred to hydrons as protons, we ignored the neutron.
@@hunter_69_69 , bro, muscle soreness and muscle fatigue are two different things. Muscle soreness happens after 12-24 hours right after a resistance training and is caused by microscopic tears on muscle fibers. Muscle fatigue, on the other hand, is caused by a high concentration of hydrogen ions. Also, lactic acid doesn't last for 1 day and is not to blame for the soreness of the muscles when it's the responsible of the satellite cells and amino acids to repair the damaged muscle tissues.
yo can u explain the major feautures of glycolysis, Krebs Cycle and Electron transport chain (Location , starting materials,and products and net ATP)? Plsssss
@@ProfessorDaveExplains for example, how much ATP it produces? Is it the same as aerobic respiration? since it also contains an electrons transport chain

MAN YOU'RE A LIFE SAVER, THIS MADE ME IMMEDIATELY UNDERSTAND RATHER THAN READING 20 PAGES OF LECTURE
You still cheated in your class 😊
I wish Prof. Dave was my actual professor 😭 he explains things so well

honestly such a well-organized and beautiful presentation
Your videos have been a huge help in my biology class! Thank you so much for putting them out!

Thank you, my bio exam is just few minutes. This video is a life saver ❤
where your long hair Dave!?!?!
agreed

Yeah 😂 where?
It was fermented
@@robertsupiter6218bro cracked the lamest joke known to humanity
Lucid explanation, pictorial presentation, simply awesome.
Your 7-minute video taught me a lot more than 3 hours of lecture by my professor. Thank you 🙏
This usually becauce the lec slide is just too much to digest

Pretty sure it just means it's better than nothing atall, since you don't have the oxygen for the more effective process.

Thank you, it has made my day and built my level of understanding.
love the intro
so addictive
I kinda have a question. When the pyruvate was decarboxylated and produced acetaldehyde, there is one hydrogen more... I didn't quite get that
Thanks Professor Dave, I have a biology test tomorrow. Can you wish me good luck?
This is very good and concise video.

Wait but isn't hydrogen made of just 1 proton (lt doesn't have any neurons)?

I am from Egypt, I loved your explanation very much, professor, even though I am in an Arab school, but I love your explanation 😆🥰
OMG! That what I learn in today on ap bio.
So well explained... everything.
Thanks alot professor Dave💕
I really understood Everything
Keep gooooiiiinnnggg😍
Actually the mechanism that causes fatigue during intense exercise is ATP hydrolysis and not lactic acid.
Oh shoot , dr dave i have a test on mbio tommorow and its on this topic!?!? Coincidence? I think not
Well explained 🙏🏻🙏🏻
The statement that lactic acid causes muscle fatigue is outdated, and false xD
Much thanks to Professor Dave, these series are very useful for reviews
I don't think it is false.
thank uu!!! your videos are so helpful❤
Professor plzzz make video on vitamins esp viatmin A and C deficiency problems...i shall be grateful to you.
Osm explanation sir . Tqsm 🙏🏼🙏🏼
Can alcohol fermentation be able to use for the production of ethanol as a bio-fuel?
yo can u explain the major feautures of glycolysis, Krebs Cycle and Electron transport chain (Location , starting materials,and products and net ATP)? Plsssss
Check my biochemistry playlist!
Isn't it need 4 NADH to make 2 ethanol? Since to make one from acetaldehyde we need 2 Hydrogen molecules. Or am I missing something?
Is lactic acid fermentation an indefinite or temporary process? What ultimately stops lactic acid fermentation?
Lactic acid is a toxic molecule, so eventually it will just kill the cell.
Is this also known as whole cell fermentation process?
THE WHOLE CELLULAR RESPIRATION PROCESS PLEASE IN A VERY DETAILED WAY
Based sigma gos professor Dave thank you
That intro is kinda cool...
Useful👍
Great job explaningb
Thanks sir❤️
What is the equation for fermentation?

PERFECT!!!
this is nice
