Within 3 weeks
Your roommate Demetrius is participating in a weightlifting course & complains of a burning pain during workouts. You explain to Demetrius that the rapid breakdown of glucose in his muscles produces large amounts of pyruvate, which leads to a fall in pH within the muscle & that the muscle responds by converting excess pyruvate to
lactate.
