5 Questions
What is the reason for the high membrane permeability of K+ in neurons?
The presence of leak channels selective for K+ ions
How do leak channels in neurons differ from other ion channels?
They are constitutively active and randomly switch between open and closed states
What is the impact of leak K+ channels on the resting membrane potential of a neuron?
They contribute to the negativity of the resting membrane potential
Which process affects the membrane potential of a cell based on ion channel activity?
Regulation of ion channel activity
What is the primary function of leak channels in neurons?
$Maintaining$ $the$ $resting$ $membrane$ $potential$
