The part of the chlorophyll molecule is embedded in the core of the thylakoid membrane, which is?
Correct answer: B. Hydrophobic
- A. Hydrophilic
- B. Hydrophobic
- C. Both A and B
- D. None of these
Explanation
The part of the chlorophyll molecule that is embedded in the core of the thylakoid membrane is the hydrophobic phytol tail. The phytol tail is a long, hydrophobic, and nonpolar structure that anchors the hydrophilic head of the chlorophyll molecule within the thylakoid membrane. This arrangement allows the chlorophyll molecules to be positioned in such a way that their hydrophilic heads are exposed to the aqueous environment of the thylakoid lumen, while their hydrophobic tails are embedded within the hydrophobic interior of the membrane. This organization is essential for the proper functioning of chlorophyll in capturing light energy 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.
