Question

A. (HT only) oxygen debt is the extra oxygen needed after exercise to react with accumulated lactic acid and remove it from cells.
B. 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.
C. (HT only) oxygen debt is not the extra oxygen needed after exercise to react with accumulated lactic acid and remove it from cells.
D. The idea only requires memorising the topic title for Respiration.

Answer

A student should select (HT only) oxygen debt is the extra oxygen needed after exercise to react with accumulated lactic acid and remove it from cells. It would help a student apply the idea in a biologically accurate way.

Explanation

This application question rewards answers that keep the biology precise. Choose (HT only) oxygen debt is the extra oxygen needed after exercise to react with accumulated lactic acid and remove it from cells. because it fits the approved curriculum point and can be applied without changing the science. If you follow 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, you move away from the required idea.

Common mistake

Misunderstanding Oxygen Debt

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.

Clarify that oxygen debt specifically refers to the additional oxygen needed after exercise to metabolize lactic acid that has built up in the muscles.
