Abstract
It is known that guanosine 3’5’-cyclic monophosphate (cyclic GMP) is the internal transmitter of phototransduction (Caretta and Cavaggioni, 1983; Fesenko et al., 1985; Yau and Nakatani, 1985b; Haynes et al., 1986; Zimmermann and Baylor, 1986) and that Ca2+ is not a positive transmitter (Matthews et al., 1985; Lamb et al., 1986) as originally proposed (Hagins, 1972). Moreover, it is known that the light-sensitive channels present in the plasma membrane outer segments of rod are activated by cyclic GMP in a cooperative way (Fesenko et al., 1985; Haynes et al., 1986; Zimmermann and Baylor, 1986).
