What is the potential metabolic fate of pyruvate during strenuous exercise?

Question

Quizplus · Accepted Answer

During strenuous exercise, there is an increased demand for energy production in muscle cells, which leads to an increase in breakdown of glucose to pyruvate through glycolysis. If oxygen availability is limited, pyruvate is converted to lactate through anaerobic fermentation in order to regenerate NAD+ for continued glycolysis. This lactate can then be transported to the liver and converted back to glucose through gluconeogenesis, allowing for continued energy production in other tissues.
