Given plants carry on respiration:
Correct answer: C. During both day and night
- A. Only during the day
- B. Only at day
- C. During both day and night
- D. Only when photosynthesis is going on
- E. Only when photosynthesis is not going on
Explanation
Respiration occurs all through the day, but the photosynthesis process occurs in the daytime, in the presence of sunlight only. Consequently, respiration becomes evident at night time in plants.

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.
