Photosynthesis consists of a photochemical reaction (Hill reaction) which occurs in the presence of light.

Explanation:

In this reaction, oxygen is released when chloroplasts are exposed to light.

In the photochemical reaction, electrons flow from H2O to NADPH2 because electrons are boosted to high energy levels by the absorbed light.

This reaction takes place in the thylakoid membranes in the chloroplast. The transfer of electrons is accomplished by a chain of electron carriers and is coupled with the phosphorylation of ADP to ATP.
