Why is respiration in plants not the same as burning?
ARespiration releases more heat than ordinary burning
BBurning needs catalysts; respiration needs only sunlight
CRespiration is stepwise enzymatic; burning is uncontrolled
DBurning happens only in cell organelles called mitochondria
Answer & Solution
Correct answer: C. Respiration is stepwise enzymatic; burning is uncontrolled
1. The chapter section 7.2 contrasts respiration with burning.
2. Respiration uses many enzyme-controlled steps.
3. Burning is a single uncontrolled chemical step.
4. So respiration is stepwise enzymatic, unlike burning.
