See all on Wikipediahttps://en.wikipedia.org/wiki/Voltage-gated_ion_channelVoltage-gated ion-channels are usually ion-specific, and channels specific to sodium (Na + ), potassium (K + ), calcium (Ca 2+ ), and chloride (Cl −) ions have been identified. The opening and closing of the channels are triggered by changing ion concentration, and hence charge gradient,

There are over 300 types of ion channels just in the cells of the inner ear. Ion channels may be classified by the nature of their gating, the species of ions passing through those gates, the number of gates (pores) and localization of proteins.
Further heterogeneity of ion channels arises when channels with different constitutive subunits give rise to a specific kind of current. Absence or mutation of one or more of the contributing typ…Wikipedia · Text under CC-BY-SA license - https://en.wikipedia.org/wiki/Voltage-gated_potassium_channel
- Voltage-gated potassium channels are transmembrane channels specific for potassium and sensitive to voltage changes in the cell's membrane potential. During action potentials, they play a crucial role in returning the depolarized cell to a resting state.

Voltage-gated proton channels are ion channels that have the unique property of opening with depolarization, but in a strongly pH-sensitive manner. The result is that these channels open only when the electrochemical gradient is outward, such …

- Voltage-gated calcium channels, also known as voltage-dependent calcium channels, are a group of voltage-gated ion channels found in the membrane of excitable cells with a permeability to the calcium ion Ca2+. These channels are slightly permeable to sodium ions, so they are also called Ca2+-Na+ channels, but their permeability to calcium is about ...

Voltage-dependent anion channels, or mitochondrial porins, are a class of porin ion channel located on the outer mitochondrial membrane. There is debate as to whether or not this channel is expressed in the cell surface membrane. This major protein of the outer mitochondrial membrane of eukaryotes forms a voltage-dependent anion-selective channel that behaves as …

Voltage-gated Sodium channels are integral membrane proteins that form ion channels, conducting sodium ions through a cell's plasma membrane. In excitable cells such as neurons, myocytes, and certain types of glia, sodium channels are responsible for the rising phase of action potentials. These channels go through three different states called resting, active and …

Calcium channel - Wikipedia Calcium channel A calcium channel is an ion channel which shows selective permeability to calcium ions. It is sometimes synonymous with voltage-gated calcium channel, [1] although there are also ligand-gated calcium channels.
