Respiratory ETS and ATP Synthase

A cofactor is a non-protein chemical compound that is bound to a protein and is required for the protein's biological activity.

In biochemistry, an oxidoreductase is an enzyme that catalyzes the transfer of electrons from one molecule to another.

ATP synthase is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate.

Most bacteria rely on proton motive force as a source of energy for a variety of cellular processes.
