Question

What is the relationship between oxygen debt and muscle fatigue and an elevated respiratory rate after exercise?

Answer 1

To illustrate this i'll use the most basic biochemical process to gain ATP, which is Glucose metabolism.

Normally cellrespiration Pyruvat+2NADH +H goes into Krebscycle to metabolise glucose to 28 ATP + 2GTP + 6 CO2 under Aerob circumstances, but during oxygen deprevation (Anaerob) Pyruvat+2NADH +H is metabolised into Lactate, which does not provide as much energy, this process gives you 2 Lactate + 2 ATP but it does it relativly fast.. When the oxygen requirements are again meet unused Lactate can convert back to Pyruvat and goes into Krebscycle.


Explaining muscle fatigue is a little more complex, Myoglubin which is a localized Oxygen storage protein gets deprevated of the oxygen inorder for the for the mitochondrias in the muscles to produce ATP.

Elevated respiration rate is due to excessive waste product created during Glucose metabolisation which if i remember correctelly produces CO6 + 6 H2O.

Clarification: The energy production does not allways start from glucose there are numoures diffrent biochemical processes in which the mitochondria can produce ATP.

Did you know that Etanol produces ATP, but inhibits a lot of the other process. This is my area of expertise so i tried to keep it as basic as possible, should you require further explanation i'd be happy to oblige.

Answer 2

Clarification: Elavated respiration rate is mostly due to Oxygen deprevation also to a small extent to excessive waste product.

Im sure there's other details i've failed to mention. But this hsould cover the basics.
