Excitable cells are cells that can change their electrical charge. This is a direct result of:

When a cell is at rest (at its resting membrane potential) it is inactive and is not using any energy.

The term “equilibrium  potential” refers to the electrical charge of the cell when:

According to the Goldman-Hodgkin-Katz (GHK) equation ions will have no effect on membrane potential if they are not permeable across the membrane.

Gated ion channels need a trigger (often described as a key) to cause them to open. These gated ion channels may be identified by the ion that they transport or by the key that opens them. The labels that describe a gated channel by the type of key needed to open a channel includes: Select all that apply
