The first stable product of the light-independent reaction having 3-carbons is:
Correct answer: B. 3-phosphoglyceric acid
- A. 3-phosphoglyceraldehyde
- B. 3-phosphoglyceric acid
- C. 1,3-biphosphate glycerate
- D. Dihydroxyacetone phosphate
Explanation
3-phosphoglyceric acid - Correct. This is the first stable 3-carbon compound formed in the Calvin cycle.

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.
