On excitation by a photon,a fate of the excited chlorophyll molecule is to
A) transfer an electron to an acceptor molecule.
B) transfer an electron to ATP.
C) relax and release a proton to a neighboring chlorophyll.
D) relax and accept an electron from a nearby donor.

Question

Quizplus · Accepted Answer

When a chlorophyll molecule absorbs a photon and becomes excited, it can transfer an electron to an acceptor molecule, which is the first step in the process of photosynthesis. This electron transfer creates a flow of electrons that eventually leads to the production of ATP and NADPH, which are used to power the synthesis of glucose. Therefore, choice A is the best choice as it accurately describes the fate of the excited chlorophyll molecule in photosynthesis. Choices B, C, and D are all incorrect as they do not accurately describe the fate of the excited chlorophyll molecule in photosynthesis.
