Cooperation of the two photosystems of the chloroplast is required for _.
Correct answer: B. Reduction of NADP
- A. ATP synthesis
- B. Reduction of NADP
- C. Cyclic phosphorylation
- D. Oxidation of the reaction center of photosystem I
Explanation
Non-cyclic photophosphorylation is the light-dependent part of photosynthesis in higher plants, in which an electron donor is required, and oxygen is produced as a waste product. It consists of two photo reactions cooperating, resulting in the "reduction of NADP+" into NADPH2. So, the correct option is 'reduction of "NADP.+"

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.
