WebPotassium channel The K channel is somewhat simpler. It contains a single class of gate consisting of 4 individual activation gates (the n -gates ), which respond more slowly than the activation gates of the Na channel. Thus if the membrane is depolarised, the n-gates open (slowly), and the K channel opens.
