Some proteins in the electron transport chain use the energy of the electrons donated by nadh and fadh2 to pump protons (h ) into the intermembrane compartment of the mitochondrion.
Electron transport chain means a series of four protein complexes that couple redox reactions which usually creates an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation
Proteins simply refers to those nitrogenous organic compounds or substances which have large molecules composed of one or more long chains of amino acids
So therefore, some proteins in the electron transport chain use the energy of the electrons donated by nadh and fadh2 to pump protons (h ) into the intermembrane compartment of the mitochondrion
