Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following characterizes the sodium-potassium pump?
A
Sodium ions are pumped out of the cell against their concentration gradient.
B
Potassium ions are pumped into the cell against their concentration gradient.
C
The pump protein undergoes a conformational change.
D
All of the above.
Explanation: 

Detailed explanation-1: -Which of the following characterizes the sodium-potassium pump? a. Sodium ions are pumped out of a cell against their gradient.

Detailed explanation-2: -Answer and Explanation: One of the main characteristics of the sodium-potassium K + pump is the ability to transport sodium Na + ions out of the cell against its gradient, as well as the ability to pump potassium into a cell against its gradient.

Detailed explanation-3: -Answer and Explanation: The sodium potassium pump is a form of active transport, as it moves solutes against their concentration gradients, and hydrolyzes ATP to do so.

Detailed explanation-4: -Which of the following characterizes the sodium-potassium pump? Sodium ions are pumped out of the cell against the concentration gradient. Potassium ions are pumped into the cell against their gradient.

Detailed explanation-5: -The sodium-potassium pump (PDB entries 2zxe and 3b8e ) is found in our cellular membranes, where it is in charge of generating a gradient of ions. It continually pumps sodium ions out of the cell and potassium ions into the cell, powered by ATP.
