The series of molecular signals generated as a consequence of a G-protein coupled receptor binding to its physiological ligand. Any process that modulates the establishment or extent of a membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane. Maintenance of the excited state of a photoreceptor cell to produce a steady state current as a result of signals generated by rhodopsin activation by a photon. Any process involved in the maintenance of an internal steady-state of ions at the level of a cell. Hyperpolarization (vertebrates) or depolarization (invertebrates) of the photoreceptor cell membrane via closing/opening of cation specific channels as a result of signals generated by rhodopsin activation by a photon. The series of molecular signals generated as a consequence of excitation of rhodopsin by a photon.
