The chemiosmotic hypothesis is a scientific theory that explains how ATP (adenosine triphosphate) is synthesized in the mitochondria of cells.
According to this hypothesis, ATP synthesis is driven by a proton gradient across the inner mitochondrial membrane.
The proton gradient is established by the electron transport chain, which pumps protons from the mitochondrial matrix to the intermembrane space.
This creates a difference in proton concentration and electrical potential across the membrane, known as the proton motive force.
ATP synthase, an enzyme located in the inner mitochondrial membrane, uses the energy from the proton motive force to convert ADP (adenosine diphosphate) and inorganic phosphate into ATP.
