Explanation: Electron transport chain
How are hydrogen ions pumped across the membrane?
Image result for what is used to make the mitochondrial membrane and is where hydrogen ions are pumped through to create ATP
During electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space. A chemiosmotic gradient causes hydrogen ions to flow back across the mitochondrial membrane into the matrix, through ATP synthase, producing ATP.
