This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: Exercise Physiology
Prompt focus: Which energy system primarily fuels a 10 second maximal sprint?
Why the correct answer works
Phosphagen (ATP-PC)
ATP-PC dominates during very short maximal efforts under 10 seconds.
Why the tempting wrong answer fails
Incorrect. The aerobic system supports prolonged moderate intensity work.
Plain-language takeaway
The phosphagen system supplies ATP rapidly from stored creatine phosphate for very short, high intensity efforts of about 0 to 10 seconds.
Simple analogy
Think of exercise physiology like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
How to review it before a retake
- Underline the command word and name what the question is asking before rereading the choices.
- Compare the correct answer against the closest distractor and write the exact detail that separates them.
- Retest this objective with a fresh question without looking at the rationale first.
