How is ATP made during the light reactions?

Asked by Oroak185

Answer (3)

In the light reaction, when electrons are transferred from photosystem 1 to photosystem 2, it goes through an electron transport chain. This ETC pumps protons into the thykaloid. Those protons diffuse out of the thykaloid through ATP synthase which energizes a phosphate group to bond to ADP. This creates ATP.

ATP made during the light reactions through the following steps

Absorption of light energy from the Sun

Generation of NADPH


The light energy which is trapped by chlorophyll from the Sun is used in the oxidation of water to generate electrons which is used in the conversion of NADP⁺ to NADPH.
The light energy also drives the conversion of ADP to ATP through the movement of protons across a membrane. These protons return through ATP synthase to make ATP.

ATP is produced during the light reactions of photosynthesis when light energy excites electrons in chlorophyll, leading to the splitting of water and the formation of a proton gradient. This gradient drives ATP synthesis via ATP synthase. Additionally, the process also generates NADPH.
