where do light reactions take place in photosynthesis?
inside organelles called chloroplasts
section::::function and chemistry.:photosynthesis.:light reactions.





























the light reactions take place on the thylakoid membranes. they take light energy and store it in nadph, a form of nadp, and atp to fuel the dark reactions.





























section::::function and chemistry.:photosynthesis.:light reactions.:energy carriers.





























atp is the phosphorylated version of adenosine diphosphate (adp), which stores energy in a cell and powers most cellular activities. atp is the energized form, while adp is the (partially) depleted form. nadp is an electron carrier which ferries high energy electrons. in the light reactions, it gets reduced, meaning it picks up electrons, becoming nadph.

chloroplast
the calvin cycle, also known as the dark reactions, is a series of biochemical reactions that fixes co into g3p sugar molecules and uses the energy and electrons from the atp and nadph made in the light reactions. the calvin cycle takes place in the stroma of the chloroplast.





























while named ""the dark reactions"", in most plants, they take place in the light, since the dark reactions are dependent on the products of the light reactions.
