Question

Which of the following is true regarding the actions of partial agonist at a ligand-gated ion channel

Maintains the ion channel in its resting state

Opens the ion channel maximally in the presence of a full agonist

Opens the ion channel more frequently than resting when a full agonist is absent

Prevents the opening of the channel in the presence of an antagonist

Maintains the ion channel in its resting state

Opens the ion channel maximally in the presence of a full agonist

Opens the ion channel more frequently than resting when a full agonist is absent

Prevents the opening of the channel in the presence of an antagonist

Explanation / Answer

Partial agonist is called as stabilizers. It will stabilize the flow of ions in the channels in concern to the presence of agonist and antagonist.It boost or deficit the activity hence called as stabilizers.

The true action is opens the ion channel more frequently than resting when a full agonist is absent. Because in the absence of the full agonist it becomes the net agonist hence can perform the activity.In the presence of agonist it does the work of antagonist.Thus it stabilize the ion flow.
