Explain define (HT only) oxygen debt as the extra oxygen needed after exercise to react with accumulated lactic acid and remove it from cells in the context of Respiration.

oxygen debt is the starting point for this answer. (HT only) oxygen debt is the extra oxygen needed after exercise to react with accumulated lactic acid and remove it from cells. A clear answer should keep that idea linked to Response to exercise in Respiration. You can support the point by showing that the extra oxygen needed after exercise to react with accumulated lactic acid and remove it from cells. Do not students often confuse oxygen debt with the amount of oxygen consumed during exercise, rather than understanding it as the extra oxygen required post-exercise to clear lactic acid; instead clarify that oxygen debt specifically refers to the additional oxygen needed after exercise to metabolize lactic acid that has built up in the muscles.

This question expects a structured explanation, not a single isolated fact. Credit comes from naming the correct idea, using precise biological vocabulary, and keeping the answer anchored to Response to exercise. Use clearly define oxygen debt in your own words, focusing on its role in post-exercise recovery. Link your answer to Response to exercise in Respiration, and keep the biology specific to exercise.
