Final answer:
During the period of oxygen debt, mitochondria do not slow their metabolism to recover ATP.
Step-by-step explanation:
The correct answer is E. Mitochondria slow their metabolism to recover ATP. During the period of oxygen debt, the body is in an anaerobic state and relies on glycolysis to produce ATP. Myoglobin replenishes stored oxygen, lactate travels to the liver to become pyruvate, glucose is stored as glycogen, and creatine phosphate is regenerated from creatine during this period.
