<prompt> Which molecules combine to form rhodopsin?Bathorhodopsin and 11-cis-retinalBathorhodopsin and all-trans-retinalBathorhodopsin and scotopsinScotopsin and 11-cis-retinal  <response>: Rhodopsin is the light-sensitive chemical in rods. Scotopsin and all-trans retinal are the breakdown products of rhodopsin, which has absorbed light energy. The all-trans retinal is conveed into 11-cis retinal, which can recombine with scotopsin to form rhodopsin
