NEET 2000 Biology question

The first step for initiation of photosynthesis will be :

(1)Photolysis of water
(2)Excitement of chlorophyll molecule due to absorption of lightCorrect
(3)ATP formation
(4)Glucose formation

Answer: (2)

Solution

Photosynthesis begins with the absorption of a photon by the antenna pigments, which raises chlorophyll a (reaction-centre P680/P700) to an excited state; the excited electron is then passed to an acceptor. Only after this do the later events occur. Photolysis of water
