Final answer:
During photosynthesis, small inorganic molecules are combined into inorganic molecules using energy from ATP.
Step-by-step explanation:
During photosynthesis, small inorganic molecules are combined into inorganic molecules using energy from ATP. ATP is one of the energy-carrier molecules produced in the light-dependent reactions of photosynthesis. It carries energy in the form of a phosphate group, and this energy is used in the light-independent reactions to fix CO₂ into organic sugar molecules.
