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 ${\text{2e}}^{\text{-}}$(two electrons) are released and then these electrons along with some additional light strikes in photosystem II. The end product of light reaction is the production of ATP and NADPH.
