Which of the Following Describes the Sodium-potassium Pump

Potassium is moved out of the cell. This pump is powered by ATP.

The Sodium Potassium Exchange Pump Sodium Potassium Pump Human Anatomy And Physiology Physiology

The sodium-potassium pump moves sodium ions out of and potassium ions into the cell.

. Pump A can fill a swimming pool in 6 hours and pump B can fill the same pool in 4 hours. Sodium ions can move down their. Which of the following correctly describe the sodium-potassium pump in neurons.

In this process an ATP is burned causing three sodium ions to be pumped out and exchanged for two potassium ions which are pumped in by a membrane protein. The sodium potassium pump is a specialized type of transport protein found in your cell membranes. It contributes to the positive resting membrane potential.

This leads to a build-up of considerable differences in the concentration of the ions on the outside and inside of the cell. The sodium-potassium pump regulates the amount of sodium and potassium inside of cells particularly nerve and muscle cells. On the cytosolic side12 The Na K ATPase pumps 3 Na out of the cell and 2K that into the cell for every single ATP consumed.

The sodium-potassium pump moves Na and K in opposite directions resulting in a net negative charge inside the cell. The sodium-potassium pump works by pumping two potassium ions into the cell and pumping out three sodium ions using the energy from an ATP molecule. Which of the following describes the movement of ions by the sodium-potassium pump.

Sodium follows its concentration gradient while. In one cycle it export 3 sodium ions out of the cell and import 2 potassium ions into the cell. The cell will swell because the water in the beaker is hypotonic relative to the cytoplasm of the RBC.

Both ions go against their concentration gradients. The pump moves three sodium ions out of a cell and two potassium ions into a cell using energy from ATP hydrolysis. Sodium ions bind to the pump and a phosphate group from ATP attaches to the pump causing it to change its shape.

Which of the following correctly describes a general property of all electrogenic pumps. Sodium-potassium pump is a ATP dependent transport anti-porter protein usually located in the plasma membrane of a cell. Question 3 Which of the following correctly describes the function of the Sodium-Potassium pump.

It brings three potassium ions into the cell for every two sodium ions pumped out. Which statements correctly describe how the sodium-potassium pump works. The cell membrane is the semi-permeable outer barrier of many cells.

Sodium is moved into the cell Potassium is moved into the cell. Active transport is the energy-requiring process of pumping molecules and ions across membranes against a concentration gradient. The outside of the cell is more positive than the inside because more positive.

It contributes to the positive resting membrane potential. The NaK pumps job is to move. 3 K in ОА.

It brings three potassium ions into the cell for every two sodium ions pumped out. Electrogenic pumps create a voltage difference across the membrane. It brings three sodium ions into the cell for every two potassium ions pumped out.

The cotransporter can also transport potassium ions. Potassium is moved out of the cell and sodium is moved into the cell. Select all that apply.

The sodium ions are moving down their electrochemical gradient while glucose is moving up. Which of the following statements correctly describes the effect the sodium-potassium pump has on the concentrations of Na and K across the plasma membrane. A substance that blocks sodium ions from binding to the cotransport protein will also block the transport of glucose.

It hydrolyses ATP in order to pump sodium and potassium in opposite directions each against its concentration gradient. The sodium-potassium pump is an active transport pump that exchanges sodium ions for potassium ions. The Na K pump is an electrogenic transmembrane ATPase first discovered in 1957 and situated in the outer plasma membrane of the cells.

Potassium inside the cell is pumped out while sodium outside the cell is pumped in. It brings three sodium ions into the cell for every two potassium ions pumped out. For each ATP that is broken down 3 sodium ions move out and 2 potassium ions move in.

Which of the following statements best describes characteristic activities of a sodium-potassium pump. In this new shape the. It brings two potassium ions into the cell for every.

Which of the following correctly describe the sodium-potassium pump in neurons.
