Cooperation of the two photosystems of the chloroplast is required for?
Correct answer: B. Reduction of NADP
- A. ATP sysnthesis
- B. Reduction of NADP
- C. Cyclic photophosphorylation
- D. Oxidation of the reaction center of photosystem
Explanation
The cooperation of two photosystems of the chloroplast is required for the reduction of NADP+ to NADPH, which is an important step in the light-dependent reactions of photosynthesis. The light energy absorbed by the photosystems is used to generate ATP and NADPH, which are used in the subsequent light-independent reactions to produce glucose. The NADPH produced by the photosystems is used as a reducing agent in the Calvin cycle, which produces glucose from carbon dioxide.

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.
