C)The receptors generate an action potential in response to chemical stimuli.
D)Complete adaptation occurs in about one to five minutes.

Question

Quizplus · Accepted Answer

Gustatory receptors undergo complete adaptation in about one to five minutes, meaning they become desensitized to a particular taste and require a stronger stimulus to generate a response. All gustatory receptors do not have the same threshold for activation, as different taste buds may be more or less sensitive to certain chemicals. The chemical does not necessarily have to be hydrophobic to be sensed, as some hydrophilic chemicals can also bind to gustatory receptors. While the receptors do generate a signal in response to chemical stimuli, it is not necessarily an action potential as gustatory cells use a different mechanism for transmission of signals.
