Question

Quizplus · Accepted Answer

Changes in cAMP levels are not a shared feature of signaling by mammalian vision and gustatory receptor pathways. In vision, changes in cGMP levels are crucial, whereas gustatory signaling involves other mechanisms that do not primarily rely on changes in cAMP levels.
