QuestionSBA
QuestionChoice
This describes what occurs when there is no agonist/neutral antagonist.
There is no response except for some negligible spontaneous channel opening.

d
When there is no agonist bound and there is no response
QuestionChoice
This describes an irreversible antagonist. This binds at the same site as an agonist and decreases the maximal response to agonists by inactivating and degrading receptors. This decreases the number of available receptors.

e
A structure which binds irreversibly at an agonist site to decrease the maximal response to agonists
QuestionChoice
This describes a full, high-efficacy agonist.

b
An agonist which when bound to a receptor opens the channel. These receptors are capable of a maximal response
QuestionChoice
This describes a partial, low-efficacy agonist.

a
An agonist which when bound to a receptor doesn't open a channel as readily. These receptors are not capable of maximal response
QuestionChoice
This describes an inverse agonist.

c
An agonist which when bound to a receptor makes the channels less likely to open
