q-during a series of sk. ms twitch, the ATP level doesnt fall appreciably, why?

a-ATP hydrolyzed onlly during relaxation
b-ATP quickly generated from creatine phosphate
c-creatine phosphate is hydrolyzed by myosin
d-the initial ATP concentration is high



plz explain ur reasoning...thankyou

the correct answer is B.

The explanation;

creatine phosphate is generated from ATP during period of low energy utilization by the action of the enzyme creatine kinase "THE creatine kinase " however during periods of intense strenuous exercise, creatine kinase is used to convert ADP back into ATP.
So it acts as energy reservoir.
