What are the requirements of chemiosmosis for ATP synthesis?

The 4 basic postulates of chemiosmosis are (1) that the membrane-located ATPase reversibly couples the translocation of protons across the membrane to the flow of anhydro-bond equivalents between water and the couple ATP/(ADP + Pi); (2) that the membrane-located respiratory chain catalyzes the flow of reducing …

Who proposed Chemiosmotic theory of ATP synthesis?

biochemist Peter Mitchell
A theory postulated by the biochemist Peter Mitchell in 1961 to describe ATP synthesis by way of a proton electrochemical coupling.

What role does chemiosmosis play in the production of ATP?

During cellular respiration, protons (H+) travel down a proton gradient by chemiosmosis. This causes the enzyme ATP synthase to turn and join a phosphate group to adenosine diphosphate (ADP), forming ATP.

What powers ATP synthesis by the chemiosmosis in cellular respiration?

The electron transport chain forms a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP via chemiosmosis.

How does chemiosmosis work in mitochondria?

Chemiosmosis is like making energy molecules by using a microscopic windmill that turns because of the wind-like flow of ions through it. Mitochondria are the membrane pouches inside of a cell that serve as the powerhouses, producing energy molecules called ATP that power the protein machines inside the cell.

How does ATP synthase work?

ATP synthase is a protein found in the thylakoid membrane that allows H+ ions to pass through it. As H+ ions pass through this protein, it rotates and binds ADP and a phosphate group together to produce ATP.

What does chemiosmosis involve?

Chemiosmosis is involved in the production of adenosine triphosphate (ATP), which is the main molecule used for energy by the cell.
