What occurs during the lactacid stage of EPOC?

Explanation:
The lactacid stage of EPOC is all about clearing the lactic acid that was produced during intense exercise. After stopping, the body uses the extra oxygen to convert and remove lactate from the muscles and blood—oxidizing it for energy or converting it back to glucose in the liver (the Cori cycle). This lactate clearance helps restore pH and return metabolic conditions toward resting levels. The other options describe processes that occur during exercise or in a different recovery phase (like replenishing ATP-PC stores) or are general post-exercise responses, not the specific lactate removal that defines this stage.
