WebThis movement of sodium ions and potassium ions across the membrane causing the wave form of the action potential starts here at the trigger zone at the axon initial segment, but then rapidly spreads in waves down the axon. First, there's the wave of depolarization from opening up the voltage gated sodium channels. WebPotassium (K(+)) channels are membrane proteins that allow rapid and selective flow of K(+) ions across the cell membrane, generating electrical signals in neurons. Thus, K(+) …

WebTwo-pore domain potassium channels (K (2P)) conduct leak or background potassium-selective currents that are mostly time- and voltage-independent. These channels play a significant role in setting the cell resting membrane potential and, therefore modulate cell responsiveness and excitability. Thus, K (2P) channels are key players in numerous ... WebThe sodium/potassium pump requires energy in the form of adenosine triphosphate (ATP), so it is also referred to as an ATPase. As was explained in the cell chapter, the concentration of Na + is higher outside the cell than inside, and the concentration of K + is higher inside the cell than outside.
