Why does the membrane have to pump sodium and potassium across the membrane and keeps pumping it?
The membranes of nerve Cells use the Sodium/Potassium pump system to charge It's membranes, for a reversal of this condition constitutes the discharge of this Action Potential - 'keeps pumping it' refers to recharging the membrane's Action Potential.
Does the sodium-potassium pump use ATP or produce ATP?
Yes. It is open to the cytoplasm and has a high affinity and three binding sites for sodium ions which dock in the trans-member protein pump. An ATP phosphorylates the pump and a conformational change causes the pump to expose the sodium ions to the extra cellular space due to low affinity for sodium ions in this conformation. This conformation has high affinity for potassium ions and two ions dock on the protein pump. The phosphate group that was on the pump disassociates and a conformational change exposes the potassium ions to the cytoplasm where they, now having low affinity for the pump, fall into the cytoplasm. The cycle repeats. and the electrical balance, slight positivity on the outside of the cell and slight negativity on the inside of the cell, is maintained.
What pumps in the cell membrane?
The sodium potassium pump is a form of active transport in which sodium and potassium end up switching places (one into the cell and one leaves the cell). The pump is located in the cell membrane.
Why is facilitated diffusion different from diffusion?
A sodium potassium pump is different from diffusion cos, it requires energy (ATP), and therefore is a active transport. Rather then diffusion which is the passive transport of solutions across cell membranes without using energy, and is determined by the concentration gradient.
How do you fulfill sodium and potassium sodium and potassium levels are low in my body please tell the best possible way to bring them in good levels?
The easy & daily sources what you can use for potassium are Potatoes,Bananas,Cooked spinach,Bamboo shoots,Oranges,Apricots, Prunes. And as everyone knows salt pure salt is the best source for sodium.
What energy source does the cell use to work the sodium potassium pump?
ATP
What protein that allows ions to actively transport across?
The transport protein allows substances to travel across the cell membrane. The substance is traveling from low concentration to a higher concentration. The process requires energy and is called active transport. The protein is simply called a transport protein.

If you use potassium hydroxide instead of sodium hydroxide what salt would you make?
potassium chloride
Is there a difference between potassium and potassium chlorhide?
Potassium chloride is a compound of potassium, and is a salt you can use as an alternative for sodium salt. Potassium itself is a chemical element and is highly reactive.
If use sodium phosphate buffer instead of potassium phosphate buffer?
its ok to use
Chemical test can distinguish sodium carbonate form potassium hydroxide?
- use a flame test to distinguish between sodium and potassium - use flame photometry to determine sodium and potassium - heat sodium carbonate and collect the gas in a beaker with water: the gas released is carbon dioxide; see the bubbles. Measure the pH; it will be more than 7.

What alkalis do you use?
Personally, I use sodium. I've heard potassium is good too, though.
Why you use potassium instead of sodium in higher blood pressure?
Potassium is a mineral used to help lower blood pressure and moderate electrolytes in the body. Sodium is basically salt, and large quantities in the body creates high blood pressure. So, it is important to have sufficient potassium, or Vitamin K, and lower sodium or salt. Potassium is good. Too much for sodium is bad.
