Final answer:
ATP and NADPH are the end products of photosynthesis, storing the energy produced by light-dependent reactions.
Step-by-step explanation:
In photosynthesis, the end products of the transformation of light energy into chemical energy are ATP and NADPH. These molecules store the energy produced by the light-dependent reactions and are then used in the light-independent reactions to build sugar molecules. ATP and NADPH are forms of chemical energy that play a crucial role in photosynthesis.
