Great video Matt! I'm in PT school right now and am studying for a Human Physiology exam I have coming up. This is extremely helpful. I love your visuals and your clear and concise explanation.
THANK YOU SO MUCH!! I AM DEFENDING MY UNDERGRAD THESIS IN TWO DAYS AND ITS ALL ABOUT CANCER METABOLISM. YOUR VIDEO HELPED ME CONNECT THE DOTS AS TO WHY CANCER CELLS USE GLYCOLYSIS PREFERABLY FOR PROGRESSION. SUCH A LIFE SAVER !!!
omgoodness this video is so helpful!! many pages of reading my text book trying to understand this ... I totally understand it after watching this 6 min vid! thanks so much!
How does ACTN3 RR effect this. I have it and it almost feels as everyone's telling me to just eat carbs and sugars to out perform others in speed sports and power sports.
thank you for your video...I am stuck on the ATP production... Glucose is a 6 carbon molecule and ATP is N/phospate molecule...how do we get ATP from glucose (I understand that energy is released when the bonds are broken)but ...where does the Phosphate and N appear? They seem to appear out of nowhere thank you
There is an inorganic phosphate molecule basically just sitting around and the energy of breaking down the glucose causes that phosphate molecule to join with an ADP molecule to form ATP.
So how does the aerobic system compliment or limit the anaerobic system? (I recently read that as a statement somewhere, so I cam across your videos in my attempted to make it make sense)
Does it mean that the reactions in aerobic glycolysis are exactly the same with the reactions in anaerobic glycolisis, and exactly with such enzymes, except for the finished product? And how from adenosine diphosphate is transformed into adenosine triphosphate, and why?
Great video. In terms of aerobic/anaerobic glycolysis, what determines if we are with or without oxygen? Is it just the duration of exercise time? Thanks!
Yes, you are correct. The duration at which you exercise at is what determines whether or not you are metabolizing in a ana/aerobic state. (With or without O2). At the initiation of workout, you start with PCr (phosphorcreatine), the duration for that is 0-8/10 sec. then at 8/10sec-2/3 mins you reach anaerobic glycolysis (substrate-level phosphorylation). Then after 2/3 mins and on you reach aerobic metabolism, an oxidative “steady” state. (Oxidative phosphorylation). The huge difference between the two is that aerobic metabolism occurs in the mitochondria (powerhouse of the cell). Producing ATP in a greater amount but at a slower rate. Hope this helps!
Outside of mitochondria aerobic glycolysis and anaerobic glycolysis happens , if the oxygen present it will go to the mitochondria ,kerbs cycle and do the oxidative phosphorylation and make 38 Atp and this the difference between aerobic glycolysis and oxidative system or anything else plz help me out .
Sounds like you have it down pretty good. Check out the video I just did on the Cori Cycle. It is also very good for giving a visual of what is going on.
Not necessarily. The body always starts alactic/ anaerobic with the ATP system then starts to work to replenish ATP with some combination of aerobic and anaerobic processes.
