The simplest and most rapid pathway for producing ATP during exercise is through

The bioenergetic pathway that first provides ATP for skeletal muscle at the onset of exercise is

If muscle glycogen is the initial substrate, the net production of ATP resulting during glycolysis is.

Which of the following metabolic processes produces the most ATP?

During strenuous exercise, oxygen used to make ATP can become depleted. How would the muscle cells respond to this?    Group of answer choicesThe muscle cells would immediately begin making ATP from glucose.The muscle cells would shut down and glycolysis would cease to function.The muscle cells would begin converting pyruvate into lactic acid through fermentation.The muscles cells would begin obtaining oxygen from other tissues in order to keep working.
