Great videos! You need to add a edit to the video because K+ is the most permeable ion to the resting membrane potential. Na+ is only slightly permeable to the resting membrane and Na+ tricking into the cell makes the cell just slightly more positive than it would be if only K+ flowed. Therefore, at resting membrane potential, the negative interior of the cell is due to much grater diffusion of K+ out of the cell than Na+ diffusion into the cell. :)

Great video. Some clarification on the establishment of the resting membrane potential: The Na/Ka-pump doesn't produce the cells resting membrane potential. It produces the electrochemical gradients that facilitates the movement of the ions across the membrane (and transport of other molecules across the membrane). What causes the resting membrane potential is the conductance or permeability (from the high number of potassium leak channels in the membrane) to potassium. This high permeability to potassium allows potassium to be the major contributor to the overall resting membrane potential, and since the equilibrium potential for potassium under physiological conditions is -90 mV, the resting membrane potential is accordingly close to this number, at around -70 mV.

at 07:33: shouldn't the potassium electrical gradient point toward the cell?
@armandohasudungan
11 жыл бұрын
Potassium is much more permeable than all those other ions. It is going against its electrical gradient, and so only a little bit will go out because of this, cause there is still negatively charged Cl- outside. However this tiny bit going against the electral gradient is enhanced because there is so much potassium inside the cell that it wants to move out against its concentration gradient. So instead of a tiny bit of potassium moving out, we have a few potassium moving out.

All information I have ever read has always stated that the flow of Sodium through leaky channels is low and the flow of K+ ions through leaky channels is high. This means you have very few sodium ions moving in and more k+ moving out. This net flow of electrical charge out in conjunction with the Na+/K+ channel causes the -70 mv difference across the membrane. ????

Why does the potassium still want to go out of the cell? Its going agains its electrical gradient right? Potassium is positively charged but still diffuses to the outside which is positively charged? Why doesnt it want to stay inside where its negatively charged?

Sorry, just to clear up, does the Na+/K+ pump create a small electrical gradient that is made stronger by the diffusion of K+ ions, or is the electrical gradient only down to the diffusion of K+ ions? My text books say the latter, but I somehow think that's wrong.
@tapaniristo3659

NaK-ATPace doesn’t have much role in action potential - it doesn’t have to. For example: amount of sodium inside cell is measured in mmol - ion channels (within ms) lets some picomole inside. Also ATPaces capacity is rather low on transporting ions. One thing is easily forgotten - diffusion of ions, when they enter in or out cells. The ions doesn’t stay in place for long - ask mr. Brown :). It’s the flux of potassium that in the end makes resting potential to recover. Check Ouabain studies on nervous system. Doc

What I don't understad is: you say K+ continue to go outside, even when their koncentration both in ICF and ECF is even. But how, when those big Anions inside the cell attract those Positive K+, that are already outside?
