SpletScore: 4.8/5 (20 votes) . This part of photosynthesis occurs in the granum of a chloroplast where light is absorbed by chlorophyll; a type of photosynthetic pigment that converts the light to chemical energy.This reacts with water (H 2 O) and splits the oxygen and hydrogen molecules apart. SpletIn the first part of photosynthesis, the light-dependent reaction, pigment molecules absorb energy from sunlight. The most common and abundant pigment is chlorophyll a. A photon strikes photosystem II to initiate …
