End product of Calvin cycle is:
Correct answer: C. Glyceraldehyde 3 phosphate
- A. 3 phosphoglycerate
- B. 1-3 biphosphoglycerate
- C. Glyceraldehyde 3 phosphate
- D. Glucose
Explanation
The Calvin cycle, part of photosynthesis, generates G3P (glyceraldehyde 3-phosphate) from three carbon dioxide molecules using ATP and NADPH. It produces six G3P molecules, one of which is used to form carbohydrates like glucose, while five regenerate RuBP to keep the cycle going.

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.
