* ATP (adenosine triphosphate): This is the energy currency of the cell.
* NADPH (nicotinamide adenine dinucleotide phosphate): This is a reducing agent (electron carrier) that carries high-energy electrons.
These two molecules are essential for the light-independent reactions (Calvin cycle) where carbon dioxide is converted into sugar.
While oxygen is also produced during the light-dependent reactions, it is a byproduct, not a primary product.
