Answer:
A. highly condensed carbon compounds, such as carbohydrates.
Step-by-step explanation:
Photosynthesis includes the transformation of the radiant energy of sunlight into the chemical energy of carbohydrates stored in their chemical bonds. The light-dependent reactions of photosynthesis temporarily store the energy of sunlight in the form of ATP and NADPH. ATP and NADHP are consumed during light-independent reactions of photosynthesis.
ATP molecules serve to drive the endothermic reactions of the Calvin cycle while NADPH serves as reducing power. In this way, their energy is transformed into the chemical energy of carbohydrates such as glucose.
