Question

Quizplus · Accepted Answer

During the "rapid" portion of the oxygen debt (or EPOC), excess VO₂ is due to restoration of muscle creatine phosphate (CP) and replacement of blood and muscle oxygen stores, as well as other factors such as elevated body temperature and elevated blood levels of epinephrine and norepinephrine. Gluconeogenesis, the formation of glucose from non-carbohydrate sources such as amino acids, occurs during the "slow" portion of the oxygen debt.

During the "Rapid" Portion of the Oxygen Debt (Or EPOC),the
