Schematic depicting two possible scenarios of rhodopsin (black circles) bleached to opsin (white circles) in disk membranes. Shaded circles represent the membrane phospholipid headgroups. (A) Bleaching monomeric rhodopsin results in independent rhodopsin and opsin monomers. (B) Bleaching dimeric rhodopsin results in herterodimers and homodimers of rhodopsin and opsin.
