Define Ligand/Chemically-gated ion channels. What stimulates a ligand-gated channel to open versus a voltage-gated channel to open? What is a voltage-gated ion channel? Describe how ligand-gated channels are related to graded potentials.
What are three ways ion channels can be gated? There are three main types of gated channels: chemically-gated or ligand-gated channels, voltage-gated channels,and mechanically-gated channels. Ligand-gated ion channels are channels whose permeability is greatly increased when some type of chemical ...
Describe how ligand-gated channels are related to graded potentials. What could be the consequence of blocking all voltage-gated calcium channels on a neuron. Speculate what the structural differences and similarities would be between ion paths of the voltage-gated K+ and Na+ channels. What type ...
The resting phase happens when the cells are dormant, and all sodium and potassium channels are closed. Depolarization happens when a stimulus is applied and will cause the ligand gated sodium channel to undergo a conformation change which allows the ion channel to open and sodium can now pass ...
Finally, cAMP can bind to and modulate the function of a family of cyclic nucleotide-gated ion channels. These are relatively nonselective cation channels that conduct calcium. Calcium stimulates CaM and CaM-dependent kinases and, in turn, modulates cAMP production by regulating the activity of ACs...

It is worth noting that, besides the true MS channels, there are also ion channels that can be modulated by mechanical stimuli but their activity is primarily dependent on factors other than mechanical force such as membrane potential or ligand concentration (Martinac and Cox 2017). Given that ...

Ohmic and Voltage-Gated Channels Leaving aside ligand-gated ion channels, the other ion channels may be either ohmic or voltage-gated. Ohmic channels exhibit a plot of the average or single channel current against φm that is linear across the zero transmembrane potential [13]. This linearity ...
