Which events take place in the light-dependent reactions of photosynthesis?

Three events occur - giving up electron absorbing sunlight by pigment, the formation of chemical energy and the replacement of electrons.

Explanation:

Light-dependent reactions are the first stage of photosynthesis that absorb light energy and produce chemical energy for the production of a sugar molecule in the second stage of photosynthesis.

Light energy is absorbed by pigments and transfer of excited electrons

ATP and NADPH production by transfer of electron and hydrogen ion

Pigments that transferred the electrons in the first event get a replacement of electron  

Thus, Three events occur - giving up electron absorbing sunlight by pigment, the formation of chemical energy and the replacement of electrons.
