Photophosphorylation

Explanation

**Step-by-Step Solution:**

1. **Definition of Photophosphorylation**:
- Photophosphorylation is a biochemical process that occurs in photosynthetic organisms. It involves the conversion of light energy into chemical energy in the form of ATP (adenosine triphosphate).

2. **Role of Light Energy**:
- During this process, light energy is absorbed by chlorophyll and other pigments in the chloroplasts. This energy is then used to add a phosphate group to ADP (adenosine diphosphate), converting it into ATP.
