The location of the phytol tail of chlorophyll b is
Correct answer: B. Thylakoid membrane
- A. Stroma
- B. Thylakoid membrane
- C. Thylakoid surface
- D. Thylakoid lumen
Explanation
Chlorophyll molecules, including chlorophyll b, have a hydrophobic phytol tail that allows them to embed firmly into the lipid bilayer of the thylakoid membrane. This hydrophobic tail ensures that the porphyrin ring, which absorbs light, is properly oriented to interact with other pigments and protein complexes in the photosystems. By anchoring chlorophyll in the thylakoid membrane, the phytol tail plays a crucial structural role, maintaining the correct organization of photosynthetic pigments and enabling efficient energy transfer 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.
