Which statement about chlorophyll is not true?

Explanation

Chlorophyll is a complex molecule involved in photosynthesis, and it does contain a terminal carbonyl group. The carbonyl group is a functional group consisting of a carbon atom double-bonded to an oxygen atom. In chlorophyll, the carbonyl group is typically present in a phytol side chain. Chlorophyll molecules consist of a porphyrin ring system with a magnesium ion at the center. The phytol side chain, which contains the terminal carbonyl group, is hydrophobic and anchors the chlorophyll molecule in the thylakoid membrane of chloroplasts. The terminal carbonyl group is involved in the overall structure and function of chlorophyll, contributing to its interaction with light and its role in capturing energy during the light-dependent reactions of photosynthesis. Chlorophyll absorbs light energy, and the carbonyl group is part of the chromophore responsible for the absorption of specific wavelengths of light.
