Question

Which property of the phytol tail of chlorophyll molecule allows it to anchor it to the thylakoid membranes?

• A. Being hydrophilic in nature
• B. Being hydrophobic in nature
• C. Having Mg as the metal ion
• D. None of the above

Answer 1

The correct option is B Being hydrophobic in nature

Phytol tail of chlorophyll is a long hydrocarbon chain that is hydrophobic in nature. It anchors the pigment to membranes of thylakoids. The hydrophobicity of the tail allows it to anchor the pigment to the membranes of thylakoids. Mg ion is present in the Porphyrin head. Porphyrin head is a complex ring similar to that in hemoglobin.
