Chemically-gated ion channels are receptor membrane proteins that are permeable to specific ions. The 'gating' part of it refers to the channel being open only once activated; which in this case will be by a chemical. An example would be the AMPA glutamate receptor, which has a channel pore that is permeable to sodium ions. Only by binding to glutamate (a neurotransmitter) does the channel allow sodium ions 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
Which component has a role in the postsynapitc cell during synaptic activity?
chemically gated channels
What kind of gated channels are involved in the generation of graded potentials?
chemically regulated gates, voltage regulated gates
Do membranes of the dendrites contain chemically gated ion channels?
Yes, the membranes of dendrites contain chemically gated ion channels. These channels open or close in response to specific neurotransmitters binding to their receptors, allowing ions such as sodium, potassium, or calcium to flow into or out of the dendrite. This ion movement is crucial for generating electrical signals in dendrites and communication between neurons.
What is the open or close in response to binding specific molecules?
Chemically-gated channels
Which membrane potential occurs because of the influx of Na plus through chemically gated channels in the receptive region of a neuron?
An excitatory postsynaptic potential, a type of graded potential, occurs because of the influx of Na+ through chemically gated channels in the receptive region, or postsynaptic membrane, of a neuron. Graded potentials are generated by chemically gated channels, whereas action potentials are produced by voltage-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
Which component has a role in the postsynapitc cell during synaptic activity?
chemically gated channels
Name two channels through which chloride ions could pass into the cell?
GABA chemically gated channels and chloride nongated channels
Which component has a role in the post synaptic cell during synaptic activity?
Chemically Gated Channels.
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 kind of gated channels are involved in the generation of graded potentials?
chemically regulated gates, voltage regulated gates
What are other names for a pore in a cell membrane?
Depends on what the pore does. If they are channels - they are called Channels. Voltage gated / ligand activated channels. If they are to communicate with neighbouring cells - they are called gap junctions.
What are mechanical gated channels?
Chemically-gated ion channels are receptor membrane proteins that are permeable to specific ions. The 'gating' part of it refers to the channel being open only once activated; which in this case will be by a chemical. An example would be the AMPA glutamate receptor, which has a channel pore that is permeable to sodium ions. Only by binding to glutamate (a neurotransmitter) does the channel allow sodium ions to enter the cell.
What happens to the neuron if sodium channels do not open?
causes chemically gated sodium channels to open
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.
