When muscle tissue is exercising under anaerobic conditions,the production of ______ is important because it ensures a continuous supply of NAD⁺.

Question

Quizplus · Accepted Answer

When muscle tissue is exercising under anaerobic conditions, glucose is converted to pyruvate through glycolysis. However, since there is no oxygen present to continue the process through the citric acid cycle and electron transport chain, the pyruvate is converted to lactate instead. This regeneration of NAD⁺ is essential for the continued production of ATP through glycolysis, which is the primary energy source during anaerobic exercise.
