The phase of photosynthesis in which sugar is synthesized by reducing CO2 is also called as dark reaction because:
Correct answer: B. It does not require light
- A. It requires darkness
- B. It does not require light
- C. It requires night period
- D. It cannot proceed in light
Explanation
It is dark reaction which uses the assimilatory power and reducing power synthesized in light reaction in reducing CO2 to synthesize carbohydrates. It may occur in light as well as in dark.

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.
