What is the consequence of transporting 3 sodium ions out of the cell and 2 potassium ions into the cell?

It moves two potassium ions into the cell where potassium levels are high, and pumps three sodium ions out of the cell and into the extracellular fluid. As is shown in Figure above, three sodium ions bind with the protein pump inside the cell. The carrier protein then gets energy from ATP and changes shape.

How many Na+ and K+ are moved into and how many are moved out of the cell?

[1][2] The Na+ K+ ATPase pumps 3 Na+ out of the cell and 2K+ that into the cell, for every single ATP consumed. The plasma membrane is a lipid bilayer that arranged asymmetrically, containing cholesterol, phospholipids, glycolipids, sphingolipid, and proteins within the membrane.

How many Na+ ions are exchanged for each 2 K+ ions?

also known as the Na+/K+ pump or Na+/K+-ATPase, this is a protein pump found in the cell membrane of neurons (and other animal cells). It acts to transport sodium and potassium ions across the cell membrane in a ratio of 3 sodium ions out for every 2 potassium ions brought in.

Which of the following is a consequence of the activity of the sodium-potassium transporters?

As a consequence of the activity of the sodium-‐potassium transporters, -intracellular sodium concentrations are kept low. -The sodium-‐potassium transporter acts to move sodium ions out of the axon thus keeping intracellular sodium concentrations at a low level.

What happens to the sodium and potassium ions when the neurons are stimulated How does their concentration inside and outside the cell change?

A stimulus first causes sodium channels to open. Because there are many more sodium ions on the outside, and the inside of the neuron is negative relative to the outside, sodium ions rush into the neuron. Remember, sodium has a positive charge, so the neuron becomes more positive and becomes depolarized.

How are potassium and sodium transported across plasma membranes?

The sodium-potassium pump transports sodium out of and potassium into the cell in a repeating cycle of conformational (shape) changes. In each cycle, three sodium ions exit the cell, while two potassium ions enter.

What will happen to the net movement of waste molecules if the Na +/ K+ pump stops working?

What will happen to the net movement of Waste molecules if the Na+/K+ Pump stops working? Net movement of Waste out of the cell will continue for some time and then all net movement of Waste in or out of the cell will stop.

How does the sodium and potassium pump work?

The sodium-potassium pump uses active transport to move molecules from a high concentration to a low concentration. The sodium-potassium pump moves sodium ions out of and potassium ions into the cell. This pump is powered by ATP. For each ATP that is broken down, 3 sodium ions move out and 2 potassium ions move in.

Which of the following would occur as a result of the inhibition of Na+ K+-ATPase?

Which of the following would occur as a result of the inhibition of Na+, K+-ATPase? Inhibition of Na+, K+-adenosine triphosphatase (ATPase) leads to an increase in intracellular Na+ concentration.

Is Na +/ K+ ATPase an antiporter?

The sodium/potassium ATPase (Na+/K+-ATPase) antiporter is an example of active transport. This active transport pump is located in the plasma membrane of every cell.

How do potassium ions move across the plasma membrane?

Since the cell membrane is impenetrable for potassium ions, it has to be translocated through specific membrane transport proteins. On the one hand, potassium channels enable the rapid, but passive influx of potassium ions.
