Question

How do muscle fibers produce ATP?

Answer 1

Explanation:

It is present in low levels in the muscle. Glycolysis converts glucose to pyruvate, water and NADH, producing two molecules of ATP. Excess pyruvate is converted to lactic acid which causes muscle fatigue. Cellular respiration produces further molecules of ATP from pyruvate in the mitochondria.
