The region of the chlorophyll molecule that helps anchor it in the membrane is the
A)Mg²+ ion.
B)chlorin ring.
C)phytol side chain.
D)tetrapyrrole ring.
E)All of the above.

Question

Quizplus · Accepted Answer

The phytol side chain is a hydrophobic tail that anchors the chlorophyll molecule into the thylakoid membrane. The Mg²+ ion is located in the center of the chlorophyll molecule and is essential for its light-absorbing properties. The chlorin ring and tetrapyrrole ring are structural components of the chlorophyll molecule, but they do not have a direct role in anchoring it in the membrane. Therefore, only choice C is the correct answer.
