Photophosphorylation is a process that occurs in the chloroplasts of plant cells during photosynthesis.
It involves the conversion of light energy into chemical energy, specifically in the form of ATP (adenosine triphosphate).
The process begins when chlorophyll absorbs light energy, which excites electrons to a higher energy state.
These high-energy electrons are transferred through a series of proteins embedded in the thylakoid membrane, known as the electron transport chain.
As electrons move through the chain, their energy is used to pump protons across the membrane, creating a proton gradient that drives the synthesis of ATP from ADP and inorganic phosphate via ATP synthase.
