Summary Introduction
To determine:
The splitting molecules that lose electrons when the light strikes to chlorophyll molecules.
Introduction:
The light reactions is takes place in the thylakoid membrane of chloroplast where the two photosystem units are present. This light reaction of photosyntesis is also called as Z scheme because the light first strike to photosystem unit I where
