Odourant Molecules Activate Sensory Neurons by

Odourant molecules activate sensory neurons by

A) binding to membrane- bound receptor proteins of sensory neurons.
B) deflecting the cilia of hairs cells, leading to the release of neurotransmitter.
C) altering basilar membrane stiffness to shift response by receptor cells.
D) binding to rhodopsin, leading to a change in cGMP levels.
E) passing through ion channels and altering membrane potentials.
