Question

Which of the following choices does NOT describe how excess postexercise oxygen consumption (oxygen deficit) restores metabolic conditions?

A-It allows lactic acid to be converted back into glycogen by the liver.
B-It replaces the oxygen removed from myoglobin.
C-It leads to increased levels of lactic acid in the muscle.
D-It allows creatine phosphate and ATP levels to be restored.

Answer 1

Excess post-exercise oxygen consumption restores metabolic conditions by replenishing ATP and creatine phosphate levels, converting lactic acid back into pyruvate, and restoring the oxygen removed from myoglobin. C) It does not lead to increased levels of lactic acid in the muscle.

Step-by-step explanation:

The correct choice that does NOT describe how excess post-exercise oxygen consumption restores metabolic conditions is C-It leads to increased levels of lactic acid in the muscle. Excess postexercise oxygen consumption, also known as oxygen deficit, is the amount of oxygen needed to restore metabolic conditions after exercise. This includes replenishing ATP and creatine phosphate levels, converting lactic acid back into pyruvate, and restoring the oxygen removed from myoglobin. However, increased levels of lactic acid in the muscle are not a part of the process of restoring metabolic conditions. Instead, excess lactic acid is transported to the liver where it can be converted back into glycogen via the Cori Cycle.
