Question

During intense exercise, muscle cells switch to lactate fermentation. What is the primary reason for this switch?

Accepted Answer

Insufficient oxygen availability leads cells to regenerate NAD+ via lactate fermentation.

Answer

Cells prefer lactate fermentation because it produces more ATP than aerobic respiration.

Answer

Lactate fermentation generates oxygen needed for aerobic processes.

Answer

Muscle cells use lactate as a primary energy source during exercise.
