Quizplus · Accepted Answer

The figure shows a chlorophyll molecule absorbing a photon, which raises an electron to the excited state. This is the process by which chlorophyll absorbs light and converts it into energy that can be used by the plant. Option A is incorrect because the electron goes from the ground state to the excited state, not the other way around. Option B is incorrect because energy is absorbed, not released, by the chlorophyll molecule. Option D is incorrect because ATP is not involved in the initial process of photon absorption by chlorophyll.
