Phosphorylation can be defined as the process of converting the energy of light into the energy of chemical bonds. It takes place in the chloroplast of cells, specifically in the thylakoid membrane. In the process of phosphorylation, light is absorbed by the chlorophyll and convert ADP into ATP molecule.
Phosphorylation is an important process occurring in the living cell because by this process energy-rich molecule called ATP is formed. In this process, the phosphate group is added to ADP to form ATP by the enzyme kinases and phosphorylases.
