Reception of taste causes:
A)an action potential that travels along the axon of a taste cell.
B)release of neurotransmitters that are detected by adjacent neurons.
C)an increase in cGMP that inactivates ligand gated Na⁺/Ca⁺² channels.
D)activation of TRPV1,which is a ligand gated Na⁺/Ca⁺² channel.

Question

Quizplus · Accepted Answer

Reception of taste causes release of neurotransmitters that are detected by adjacent neurons, which initiate a signal transduction pathway ultimately leading to the perception of taste. Option A is incorrect because taste cells themselves do not generate action potentials; they rely on adjacent neurons to transmit the taste signal. Option C is incorrect because an increase in cGMP would activate, not inactivate, ligand-gated ion channels. Option D is incorrect because TRPV1 is not primarily involved in taste reception, but is instead a receptor for capsaicin and heat.
