When a new hydrogen ion enters, the top part of the ATP synthase complex rotates.The hydrogen ions provide energy for the synthesis of ATP molecules.ÊÊ
The protein channel is called ATP synthase. It functions in the mitochondrion by allowing hydrogen ions to flow back into the matrix through the channel, which generates ATP in the process known as oxidative phosphorylation.
Hydrogen ions diffuse back through the ATP synthase protein complex located on the inner mitochondrial membrane. This process harnesses the energy from the electrochemical gradient to produce ATP.
If hydrogen ion concentration in the inter membrane space and matrix of a mitocondria reach equilibrium then ATP synthase, which relies on a high concentration of hydrogen ions in the intermembrane space will work slower, letting less hydrogen ions into the matrix, while proteins in the electron transport chain pump hydrogen ions into the intermembrane space at a faster rate, destroying the equilibrium.
Protein channels in hydrogen ion pumps, such as the F0 portion of ATP synthase, facilitate the movement of hydrogen ions (protons) across a membrane. This movement creates an electrochemical gradient that is used to generate ATP in cellular respiration. The protein channel allows only hydrogen ions to pass through, maintaining the integrity of the membrane.
High concentration of H+ ion in the intermembrane lead to the movement of H+ ions into the inner membrane
ATP synthase is the protein complex that allows hydrogen ions to flow out of the thylakoid membrane during photosynthesis. This flow of hydrogen ions creates a proton gradient that drives the production of ATP, which is a molecule that stores energy for the cell to use.

Inside the intermembrane space, there is a buildup of hydrogen ions from the ETC. The hydrogen ions go down the concentration gradient through ATP synthase, producing ATP.

Hydrogen ions flow back down their gradient through a channel in an ATP synthase. The ATP synthase harnesses the proton-motive force to phosphorylate ADP, forming ATP.Read more: How_does_chemiosmosis_produce_ATP
The ATP synthase
Hydrogen ions move from the outer to the inner compartment of the mitochondria through the enzyme ATP synthase, which is embedded in the inner membrane. This movement of hydrogen ions creates an electrochemical gradient that drives ATP production.
