5.2: The Light-Dependent Reactions of Photosynthesis

WebIn the light reactions the H2O IS SPLIT and O2 IS RELEASED. Inaddition, the LIGHT EXCITED ELECTRONS OF CHLOROPHYLL are passed down to ELECTRON TRANSPORT CHAIN producing ATP by CHEMIOSMOSIS; in addition the light excited electrons of chlorophyll REDUCE NADP+ TO NADPH. WebThe energy given to the electron then travels from one pigment molecule to another until it reaches a pair of chlorophyll a molecules called the reaction center. This energy then excites an electron in the reaction center causing it to break free and be passed to the primary electron acceptor.
