Yes, it can a gated ion channel is opened when a signal molecule binds to a receptor protein causing the receptor protein to open the ion channel through the cell membrane and after this process the ion channel is closed once again to prevent various molecules to enter the cell.

What is the open or close in response to binding specific molecules?
Chemically-gated channels
Plasma membrane exhibits chemically gated ion channels?
Yes, many cells have chemically gated ion channels. This means that the channel requires a specific chemical to open the gate and allow for things to pass through the membrane
What cell gates open immediately after action potential peak?
Sodium and potassium voltage gated ion channels.
The term voltage regulated means that the?
membrane voltage gated ion channels open and close with changes in the membrane potential
Which ion channel opens in response to a change in membrane potential and participates in the generation and conduction of action potentials?
Sodium channels. A neuron's membrane potential may depolarize for many reasons (neurotransmitters, mechanical deflection, electrical synapse, etc). When that membrane depolarizes to the point of its threshold of activation, then voltage gated channels open up an allow an influx of sodium into the cell. This rapidly depolarizes the cell's membrane, causing that upward peak or rising phase to occur.
What is it that ion channels may be always or have?
They may be always open or they may have close gated channels
What changes occur to voltage-gated Na and K channels at the peak of depolarization?
Inactivation gates of voltage-gated Na+ channels close, while activation gates of voltage-gated K+ channels open.
Which ion channels open in response to a change in membrane potential?
voltage-gated ion channels
What is the open or close in response to binding specific molecules?
Chemically-gated channels
When an action potential arrives at the axon terminal of motor neuron which ion channels open?
voltage-gated calcium channels
What areas of the neuron generate signals that open these voltage gated channels?
anan zaaa
What is a stimulus gated channel?
There are voltage-gated ion channels and ligand-gated ion channels, and since both are stimuli the term stimulus-gated is a redundancy.
What happens to the neuron if sodium channels do not open?
causes chemically gated sodium channels to open
How does graded potential occur?
Graded potential occurs when triggered by a stimulus and gated ion channels open these gated channels can either be chemically gated or mechanically gated. In order to have graded potential threshold must be met in order to generate action potential. Good day!
What are channels of production?
Voltage Gated channels
Which type of membrane channels are found at the axon?
Voltage-gated Na+ and voltage-gated K+ channels
Plasma membrane exhibits chemically gated ion channels?
Yes, many cells have chemically gated ion channels. This means that the channel requires a specific chemical to open the gate and allow for things to pass through the membrane
