When rhodopsin absorbs light, its retinal cofactor isomerizes from the 11-cis to the all-trans configuration, and the protein subsequently undergoes a series of relaxations to accommodate the altered shape of the isomerized cofactor.
Cando a rodopsina absorbe luz, o seu cofactor retinal isomerízase da configuración 11-cis á todo-trans, e a proteína sofre seguidamente unha serie de relaxacións para acomodar a forma alterada do cofactor isomerizado.
