The main purpose of light capturing reaction is to turn light energy into chemical energy. The chemical energy that is made available by the light-capturing reaction will be used by the Calvin cycle to fuel sugar molecules.
The light-dependent reaction makes use of light energy to produce two molecules (ATP and NADPH) which are very essential for the next stage of production to take place.
The two molecules that are produced by the light-dependent reaction are used to produce sugar molecules that are required for the Galvin cycle to take place
The transfer of electrons that occurred during the Light-dependent reaction was made possible by the capturing of energy from the sun which takes place in the chlorophyll.
Photosystems also play a significant role in the light reactions. they are made up of large complexes and proteins that capture light during the energy transforming process.
The photosystems are of two types: photosystem I (PSI) and photosystem II (PSII), the two photosystems are made up of pigments that help to capture light energy and also helps to collect pairs of molecules.
Therefore, the main purpose of light capturing reaction is to turn light energy into chemical energy
