Question

The first event in photosynthesis is (A) Synthesis of ATP (B) Photoexcitation of chlorophyll and ejection of electron (C) Photolysis of water (D) Release of oxygen

Tardigrade Admin · Accepted Answer

Photoexcitation of chlorophyll and ejection of the electron is the pilot event of the photosynthetic process. When a photon of light energy falls on a chlorophyll molecule, one of the electron pairs from the ground or singlet state passes into a higher energy level called excited singlet state.
