Worked practice questions

Anaerobic respiration in human muscles produces:

  1. Ethanol + CO₂
  2. Pyruvate + H₂O
  3. Glucose + O₂
  4. Lactic acid
Show answer and solution

Correct answer: D. Lactic acid

1. During strenuous exercise, muscle cells run out of O₂. 2. Glucose is broken down to LACTIC ACID (not ethanol — that's yeast). 3. The accumulating lactic acid causes muscle cramps and soreness. 4. Recovery (oxygen debt) converts lactic acid back to pyruvate. _Source: syllabus Science Ch 5 §5.2 Anaerobic Respiration_
