Question

Draw what an action potential would look like if you inhibited the voltage-gated K+ channels.

Answer 1

The above graph depicts what an action potential will look like when the voltage-gated potassium channels are inhibited.

Since voltage-gated K+ channels are normally involved in repolarization, so when these channels are inhibited, repolarization will not happen so quickly. As the resting K+ channels that exist in the membranes of all cells remain open, only repolarization will happen more slowly. This will eventually lead to repolarization of the cell.
