photophosphorylation

Photophosphorylation is a process used by plants, algae, and some bacteria to generate energy. During photosynthesis, these organisms capture sunlight and convert it into chemical energy. In this process, light energizes electrons that travel through a series of proteins called the electron transport chain inside chloroplasts. As electrons move, they help produce a molecule called ATP, which is the main energy currency for cells. Essentially, photophosphorylation uses sunlight to add a phosphate group to ADP, creating ATP, which powers various biological activities.
