Help with Anatomy and Physiology please?
a. the amount of oxygen converted to lactic acid during exercise
b. conversion of pyurvic acid to lactic acid
c. the amount anaerobic metabolism must increase after exercise
d. the amount of oxygen that cells need to replenish Atp supplies after exercise
e. the amount of carbon dioxide that cells need to eliminate
Answer:
D
During muscular exercise, blood vessels in muscles dilate and blood flow is increased in order to increase the available oxygen supply. Up to a point, the available oxygen is sufficient to meet the energy needs of the body. However, when muscular exertion is very great, oxygen cannot be supplied to muscle fibers fast enough, and the aerobic breakdown of pyruvic acid cannot produce all the ATP required for further muscle contraction.
d sounds like a good answer
