Quick explanation
Explain that long periods of vigorous activity can cause muscles to become fatigued and stop contracting efficiently
- This point belongs to Respiration, especially Response to exercise.
- You need to be able to explain that long periods of vigorous activity can cause muscles to become fatigued and stop contracting efficiently.
- The key ideas to know are activity, vigorous, and that.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Response to exercise to exam-style questions, flashcards, and revision notes for Respiration.
Quick student answer
How do you explain long periods of vigorous activity can cause muscles to become fatigued and stop contracting efficiently?
Direct answer
In Biology, this page helps you answer questions about long periods of vigorous activity can cause muscles to become fatigued and stop contracting efficiently within Respiration. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are muscle fatigue and efficient contraction.
Key terms
- muscle fatigue: A condition where muscles become tired and less effective at contracting due to prolonged vigorous activity.
- efficient contraction: The ability of muscles to contract effectively, which can be impaired during long periods of vigorous activity.
Common trap
Muscle Fatigue Misunderstanding: Emphasize that muscle fatigue can also result from the accumulation of lactic acid due to anaerobic respiration when oxygen supply is insufficient.
