English: Model of the energy generating mechanism in marine bacteria. When sunlight strikes a rhodopsin molecule (1), it changes its configuration such that a proton is expelled from the cell (2). The chemical potential causes the proton to flow back into the cell (3), thus generating energy (4) in the form of adenosine triphosphate (5).
