Final answer:
The light-dependent reactions of photosynthesis produce ATP and NADPH, which are used in the light-independent reactions to produce glucose.
Step-by-step explanation:
The light-dependent reactions of photosynthesis produce ATP and NADPH as the two major products.
During the light-dependent reactions, energy from sunlight is used to convert ADP (adenosine diphosphate) into ATP (adenosine triphosphate) and NADP+ (nicotinamide adenine dinucleotide phosphate) into NADPH (reduced form of NADP+).
These energy-carrying molecules, ATP and NADPH, are then used in the light-independent reactions, also known as the Calvin cycle, to convert carbon dioxide (CO2) into organic sugar molecules, such as glucose.
