In plants, energy is released during the process of:
Correct answer: B. Respiration
- A. Photosynthesis
- B. Respiration
- C. Transpiration
- D. Water absorption
Explanation
The correct answer is respiration. In cellular respiration, plants break down glucose molecules to release energy stored in their chemical bonds, which is then transformed into ATP. This is an energy-releasing process and occurs in all living organisms, including plants.Photosynthesis is incorrect because it is an energy-storing process, not a releasing process. Transpiration and water absorption are incorrect because they involve the movement of water and nutrients, not the release of energy.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
