First stable compound during Calvin cycle is:
Correct answer: A. 3-phosphoglycerate
- A. 3-phosphoglycerate
- B. Glyceraldehyde 3 - phosphate
- C. 1, 3 bisphosphoglycerate
- D. Ribulose bisphosphate
Explanation
The first stable compound formed during the Calvin Cycle is 3-phosphoglycerate (3-PGA). The Calvin Cycle, also known as the light-independent reactions of photosynthesis, is a series of enzyme-catalyzed reactions that take place in the stroma of chloroplasts. The cycle begins with the process of carbon fixation, where carbon dioxide from the atmosphere is combined with a five-carbon sugar called ribulose-1,5-bisphosphate (RuBP) using the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO).

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.
