The role of these hydrogen atoms is shown in the electron carrier system.

Web3 years ago. Oxidative phosphorylation is a process involving a flow of electrons through the electron transport chain, a series of proteins and electron carriers within the mitochondrial membrane. This flow of electrons allows the electron transport chain to pump protons to one side of the mitochondrial membrane. Meaning that it is not the same.
