Betel is developing a model of the process of photosynthesis. one of her goals is to identify the products of photosynthesis that will later be used to assemble sugars, lipids, amino acids, and other essential compounds for the organisms. in which part of the model should these products be identified? a. in the light-dependent reactions, where water molecules are split b. in the light-dependent reactions, where atp is synthesized c. in the light-independent reactions, where carbon dioxide enters the cycle d. in the light-independent reactions, where 3-carbon sugars exit the cycle
