Na and K ions. What side are they released from the sodium-potassium pump?

Question

On what side of the membrane are Na + ions released from the pump?

On what side of the membrane are K + ions released from the pump?

I don't understand what they mean by side, and where you look from your eye.

Answer 1

by "side" it means what side of the plasma membrane do each ion get released or transported to.

K+ is more concentrated inside the cell and Na+ is more concentrated outside the cell.

When the pump is activated via ATP K+ from inside the cell binds to the receptor/pump and when ATP is converted to ADP (by removing a phosphate) the receptor changes shape so that the K+ can now exit to the outside of the cell (or extra cellular matrix)
At this point ADP is still bound to the receptor/pump and now Na+ from outside the cell in the extracellular matrix can bind to receptors located on the pump. Next ADP is removed from the receptor/pump causing another confirmational change and now the receptor/pump faces the inside of the cell or intracellular matrix. With No ADP present, Na+ unbinds and is released into the cell.

I hope this helps! Best of Luck!

Answer 2

You are talking about a cell. You have an outside and an inside. K is in the inside and Na is on the outside. The pump is to pump the Na out. The outside of the membrane is positively charged, and the inside is negatively charged.

Answer 3

DarkJ had some inaccuracies, yet was once virtually suited. a million. with regard to ion concentrations, ok is severe throughout the cellular and occasional exterior (the opposite of Na). 2. "cost" and "benefit" shouldn't the comparable ingredient. For the resting neuron, there's a small plenty extra advantageous than poor "costs" interior the mobile and this produces the damaging membrane "capabilities". the understanding is what drives the action of costs. 3. The stages of Na and ok throughout the telephone are restored by ATP-pushed pumps, now no longer by employing ion channels. the tactic calls for power through fact the process ion flow is opposite to what could arise passively.

Answer 4

Outside of the cell (extracellular), or inside of the cell (intracellular).
