The reaction centre of photosystem have:
Correct answer: C. One or more molecules of chlorophyll a and primary electron acceptor
- A. One molecule of chlorophyll a and primary electron acceptor
- B. Many molecule of chlorophyll a and primary electron acceptor
- C. One or more molecules of chlorophyll a and primary electron acceptor
- D. Chlorophyll a, chlorophyll b and primary electron acceptor
Explanation
Reaction center of photosynthesis lies in chlorophyll a. It consists of one or more molecules of chlorophyll a along with a primary electron acceptor and associated electron carrier of electron transport system. Chlorophyll a molecules of reaction center and associated proteins are closely linked to the nearby electron transport system.

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.
