Which one is not an energy releasing process?
Correct answer: B. Photosynthesis
- A. Glycolysis
- B. Photosynthesis
- C. Respiration
- D. Krebs Cycle
Explanation
The correct answer is Photosynthesis. Photosynthesis is an endothermic process, meaning it requires energy input from sunlight to convert carbon dioxide and water into glucose and oxygen. In contrast, Glycolysis, Respiration, and the Krebs Cycle are all exothermic processes that release energy stored in glucose molecules to produce ATP, which is used by cells for various functions.

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.
