What type of pump is sodium-potassium pump?
active transport pump
The sodium-potassium pump is an active transport pump that exchanges sodium ions for potassium ions.
What is the sodium potassium pump an example of quizlet?
Sodium-potassium pump is an example of passive transport.
Is the sodium potassium pump is an example of active transport?
Secondary active transport uses the energy stored in these gradients to move other substances against their own gradients. As an example, let’s suppose we have a high concentration of sodium ions in the extracellular space (thanks to the hard work of the sodium-potassium pump).
What is the sodium potassium pump in biology?
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 …
What is the sodium-potassium pump quizlet?
It is a vital transmembrane ATPase found in animal cells. It moves sodium ions out of cells & potassium ions into cells against steep conc.
What is sodium pump mechanism?
1 : a molecular mechanism by which sodium ions are transferred across a cell membrane by active transport especially : one that is controlled by a specialized plasma membrane protein by which a high concentration of potassium ions and a low concentration of sodium ions are maintained within a cell.
What is the sodium potassium pump quizlet nutrition?
The sodium-potassium pump maintins fluid balance between intracellular and extracellular fluid. This pumps potassium into the cell and sodium ions out of the cell.
How do sodium potassium pumps work quizlet?
To pump sodium ions out of the cell and potassium ions into the cell. The source of energy used to power the sodium potassium is the breakdown of ATP.
Is potassium active or passive transport?
The sodium-potassium pump carries out a form of active transport—that is, its pumping of ions against their gradients requires the addition of energy from an outside source.
What is an example of active transport?
Examples of active transport include the transportation of sodium out of the cell and potassium into the cell by the sodium-potassium pump. Active transport often takes place in the internal lining of the small intestine.
What is the sodium potassium pump quizlet?
What is the sodium potassium pump made of?
The portion of the sodium-potassium pump that crosses the membrane is composed of a bundle of alpha helices. Many other membrane-bound proteins have similar bundles of alpha helices.
