Final answer:
Energy in photosynthesis is transferred from sunlight to electrons in chlorophyll molecules, which are then bounced to carrier molecules. ATP holds chemical energy temporarily, and glucose stores the final energy needed for all living things.
Step-by-step explanation:
In photosynthesis, energy is transferred from sunlight to electrons in chlorophyll molecules, which are then bounced to a series of carrier molecules. These carrier molecules gradually lose energy at each step, which is used to perform cellular tasks. One of the short-term energy carrier molecules important to photosynthesis is ATP, which holds chemical energy temporarily and is used to build sugar. Eventually, the energy is stored in the form of glucose, a carbohydrate molecule that contains the energy needed for all living things to survive.
