Solution
The correct option is C ATP In photosynthesis reaction, energy is transferred from the light reaction step to dark reaction step by ATP. Photosynthesis is divided into two sets of reactions: the light-dependent (light) reactions and the light-independent (dark) reactions.
The energy in light is transferred to these electrons and is then used to generate adenosine triphosphate ( ATP) and the electron carrier NADPH. These two products carry the energy and electrons generated in the light reactions to the stroma, where they are used by the dark reactions to synthesize sugars from CO2.
