The rod photoreceptors in the eye are extremely sensitive to light.The cells sense light through a signal transduction cascade involving light activation of a GPCR that activates a G protein that activates cyclic GMP phosphodiesterase.How would you expect the addition of the following drugs to affect the light-sensing ability of the rod cells? Explain your answers.
A.a drug that inhibits cyclic GMP phosphodiesterase
B.a drug that is a nonhydrolyzable analog of GTP
