Which membrane protein is responsible for restoring the original concentration of Na plus and K plus?
Sodium potassium pump is responsible for restoring the original concentration of Na plus and K plus.
The sodium potassium pump prevents the accumulation of?
Sodium potassium pump prevents accumulation of K out side of cell and Na inside of cell.
Which channel maintains the concentration gradients of ions across a neuronal membrane?
The sodium- potassium pump pump moving Na+ ions out and K+ ions in
What value is the active transport of potassium ion which requires ATP?
Na+/K+ ATPase active transport pump
Through what type of proteins does active transport occur?
A carrier protein (as opposed to a channel protein). An example of a carrier protein is the Na+/K+ pump.
Is the sodium potassium pump the main driving force of Na movement into a renal cell?
the Na/ K pump
What event initiates ATP attachment to the Na plus -K plus pump leading to the pump's phosphorylation?
The binding of Na+ ions to the pump
The sodium-potassium pump transports what?
Na+ out of the cell and K+ into the cell
What sort of ion distributions are established and maintained by Na -K pump activity?
high Na+ concentration in the extracellular fluid; high K+ concentration in the cytoplasm
Which membrane protein is responsible for restoring the original concentration of Na plus and K plus?
Sodium potassium pump is responsible for restoring the original concentration of Na plus and K plus.
The sodium potassium pump prevents the accumulation of?
Sodium potassium pump prevents accumulation of K out side of cell and Na inside of cell.
Why is the sodium-potassium pump called an electrogenic pump?
pumps unequal quantities of Na+ and K+ across the membrane, 3Na+ out of and 2 K+ into the cell per pump cycle. In other words, it generates electricity by producing a net movement of positive charge out of a cell.
Which channel maintains the concentration gradients of ions across a neuronal membrane?
The sodium- potassium pump pump moving Na+ ions out and K+ ions in
Is the sodium potassium pump a carrier protein?
the carrier protein of Na-k pump is an ion carrier protein and the pump cannot be termed as the carrier protein its a biochemical phenomenon
What is a sodium potassium pump?
sodium-potassium pump, in cellular physiology, a protein that has been identified in many cells that maintains the internal concentration of potassium ions [K+] higher than that in the surrounding medium (blood, body fluid, water) and maintains the internal concentration of sodium ions [Na+] lower than that of the surrounding medium. The pump, which has adenosine-triphosphatase (ATPase) activity, traverses the cell membrane and is activated by external [K+] and internal [Na+]. This enzyme uses metabolic energy to transport (pump) Na+ outward and K+ inward. The resting potential of cells and related bioelectric phenomena such as the action potential depends on the steady-state difference in concentrations of Na+ and K+ maintained by the pump.
Why hyperventilation can be one of the causes of hypernatremia?
Hypernatriemia (excess Na, sodium ions in the blood) is a result of ineffective breathing, depletion of more Na, as the true mechanism for Na-K pump fails
What value is the active transport of potassium ion which requires ATP?
Na+/K+ ATPase active transport pump
