The light-dependent reactions use light energy to make two molecules: ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

The high-energy electron is passed to an acceptor molecule and replaced with an electron from water. This splitting of water releases the O2.
The high-energy electron travels down an electron transport chain, losing energy as it goes. Some of the released energy drives pumping of H+ ions from the stroma into the thylakoid interior, building a gradient. As H+ ions flow down their gradient and into the stroma, they pass through ATP synthase. Driving ATP production in a process known as chemiosmosis
