Web(b) Iron and steel in the presence of water and oxygen form rust. Fe2+ goes into solution oxygen dissolved in water electrons move in metal colourless gas forms The reactions involved are: reaction 1 Fe → Fe2+ + 2e– The electrons move through the iron on to the surface where a colourless gas forms. reaction 2 Fe2+ + 2OH– → Fe(OH) 2 from ... WebEnergy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis. Together, the electron transport chain and chemiosmosis make up oxidative phosphorylation. The key steps of this process, shown in simplified form in the diagram above, include:
