In muscle cells, glycolysis is the first set of reactions involved in the metabolism of glucose. This process creates pyruvate from glucose while creating a few ATP and NADH molecules. On the other hand, lactate dehydrogenase is an enzyme used in the fermentation process for the formation of pyruvate from lactate.
What would be the limiting factor for ATP production by glycolysis in a strenuously-exercising muscle that lacks lactate dehydrogenase?
A. the supply of NAD+
B. increased acidity from lactic acid, causing muscle damage
C. the supply of pyruvate
D. the supply of ADP
E. the supply of O2
