During dark reaction of photosynthesis:
Correct answer: A. CO2 is reduced to organic compound
- A. CO2 is reduced to organic compound
- B. Chlorophyll is activated
- C. 6C sugar is broken down into 3C sugar
- D. Photolysis
Explanation
This statement is correct. During the Calvin cycle, carbon dioxide is reduced and incorporated into organic compounds, ultimately leading to the formation of glucose. Reduction in this context refers to the addition of electrons and hydrogen to CO2 to form more complex organic molecules.

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.
