The electrons excited from photo system-II pass directly to:
Correct answer: C. Plastoquinone
- A. Ferredoxin
- B. Plastocyanin
- C. Plastoquinone
- D. Carotenoids
Explanation
Plastoquinone is a lipophilic molecule that functions as an electron carrier in the electron transport chain of photosynthesis. It is a quinone derivative and plays a crucial role in transferring electrons from photosystem II (PSII) to the cytochrome b6f complex during the light-dependent reactions of photosynthesis.

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.
