- A. Define (HT only) oxygen debt as the extra oxygen needed after exercise to react with accumulated lactic acid and...
- B. A statement about another biology topic rather than Respiration
- C. A revision technique rather than the scientific idea being tested
- D. A reversed cause-and-effect version of the objective
Answer
Define (HT only) oxygen debt as the extra oxygen needed after exercise to react with accumulated lactic acid and... is the best answer for this Respiration objective.
Explanation
Define (HT only) oxygen debt as the extra oxygen needed after exercise to react with accumulated lactic acid and... is supported by the approved learning objective: "Define (HT only) oxygen debt as the extra oxygen needed after exercise to react with accumulated lactic acid and remove it from cells". It stays within Respiration, uses the key idea "define (HT only) oxygen debt as the extra oxygen needed after exercise to react with accumulated lactic acid and remove it from cells", and avoids distractors that either switch topic, describe a study method, or reverse the biology relationship.
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.
