First phase of Calvin cycle is:
Correct answer: C. Fixation of CO2
- A. Reduction of CO2
- B. Regeneration of CO2 acceptor
- C. Fixation of CO2
- D. Regeneration of RuBP
Explanation
In first phase CO2 is condensed with RuBP in presence of Rubisco. It is called fixation of CO2.

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.
