Vedclass · Answer

(D) The light-dependent reaction (or light reaction) of photosynthesis occurs in the thylakoid membranes of the chloroplast.$1$. Absorption of light energy: Chlorophyll pigments absorb light energy to excite electrons.$2$. Splitting of water (Photolysis): Water molecules are split into $H^+$,electrons,and $O_2$.$3$. Release of $O_2$: Oxygen is released as a byproduct of water splitting.$4$. Formation of $ATP$ and $NADPH$: Through the electron transport chain and chemiosmosis,$ATP$ and $NADPH$ are synthesized,which are essential for the subsequent dark reaction (Calvin cycle).Therefore,all the mentioned processes occur during the light reaction.
