WebThis "proton" gradient is what drives oxidative phosphorylation. The rest just ends up as heat. As far as I can tell the hydrogen ions come from hydronium (H₃O⁺), which is naturally present in all aqueous solutions. Note that "consuming" H⁺ in the matrix increases the "proton" gradient across the IMM, so this helps with energy production. WebJan 11, 2024 · These changes generally involve transfer of electrons (from a metal atom to a non-metal) or sharing of electrons (typically between two non-metals). The transfer of electrons results in what is known as an ionic bond between atoms, while sharing of electrons creates a covalent bond.
