The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
The dark reaction occurs in the stroma of the chloroplast where they utilize the products of the light reaction.
The dark reaction in the stroma.
Light reaction in thylakoid membranes.
