Biology
Which of the following is a catabolic process ?
- Photosynthesis
- Respiration
- Both (a) and (b)
- None of these
Answer
Respiration
Reason — Respiration is a catabolic process because it breaks down glucose into simpler substances (carbon dioxide and water) and releases energy.
Photosynthesis is an anabolic process that leads to the formation of glucose while respiration (a catabolic process) leads to the breakdown of glucose molecules.
