Which one is a light gathering structure?
Correct answer: A. Antenna complex
- A. Antenna complex
- B. Reaction center
- C. Photosystem
- D. None of these
Explanation
The correct answer is the antenna complex. It is specifically designed to gather light by capturing photons through its pigments, such as chlorophyll and carotenoids, and transferring the energy to the reaction center. The reaction center itself is not a light-gathering structure but a site where the energy is utilized to initiate electron transport. The photosystem consists of both the antenna complex and the reaction center, but the antenna complex is the component responsible for light gathering. Therefore, 'None of these' is incorrect because the antenna complex is indeed a light-gathering structure.

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.
