Correct answer: C. Plastocyanin
- A. Cytochrome
- B. Plastoquinone
- C. Plastocyanin
- D. Ferredoxin
Explanation
Plastocyanin is a copper-containing protein that is found in the thylakoid membranes of chloroplasts. It is a blue protein that helps to transfer electrons from Photosystem II to Photosystem I in 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.
