Each photosystem consists of a light gathering:
Correct answer: C. Antenna complex and a reaction centre
- A. Antenna complex
- B. Reaction complex
- C. Antenna complex and a reaction centre
- D. Primary electron acceptor
Explanation
Each photosystem consists of a light gathering antenna complex and a reaction center. The antenna complex has many molecules of chlorophyll-a, chlorophyll-b and carotenoids, most of them channeling the energy to reaction center.

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.
