The first stable product of Calvin cycle is:
Correct answer: A. 3-phosphoglycerate
- A. 3-phosphoglycerate
- B. 1. 3 biphosphoglycerate
- C. Glyceraldehyde - 3 phosphate
- D. Ribulose - 5 - phosphate
Explanation
3-phosphoglycerate (3-PG) is an important intermediate compound in the Calvin cycle, which is a series of biochemical reactions that occur during the light-independent reactions of photosynthesis. The Calvin cycle takes place in the stroma of chloroplasts and is responsible for the conversion of carbon dioxide into carbohydrates.

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.
