1. ATP (adenosine triphosphate): This is the energy currency of the cell. It is produced by using the energy from light to power the synthesis of ATP from ADP (adenosine diphosphate) and a phosphate group.

2. NADPH (nicotinamide adenine dinucleotide phosphate): This is a reducing agent, meaning it carries electrons. It is produced by using the energy from light to reduce NADP+ to NADPH.

These two molecules are then used in the Calvin cycle (dark reaction) to convert carbon dioxide into sugar.
