In which of the following processes is light energy converted to ATP?

The process in which light energy is converted to ATP is photosynthesis. During photosynthesis, plants use the energy from sunlight to convert carbon dioxide and water into glucose, a type of sugar. This process occurs in the chloroplasts of plant cells and involves two main stages: the light-dependent reactions and the light-independent reactions. In the light-dependent reactions, light energy is absorbed by pigments called chlorophyll and converted into ATP and NADPH. These energy-rich molecules are then used in the light-independent reactions to fuel the production of glucose. So, Photosynthesis is the correct answer.
