Identify the correct statement about sodium potassium pumps

a. They are an example of simple passive diffusion

b. They run all of the time as long as calcium is present

c. They run all of the time as long as ATP is present

d. They pump 3 sodium molecules into the cell and 2 potassium molecules out of the cell

c. They run all of the time as long as ATP is present

Explanation:

The Sodium-potassium pump is an enzyme found in many cell membranes, and it performs many functions in cell physiology. The correct answer is that it runs all the time as long as ATP is present because it uses energy from ATP and for every ATP molecule that pump uses, it moves 3 sodium ions out and 2 potassium ions in.

The Na + / K + pump run all the time as long as ATP is present.

Explanation:

It is a very important protein for cellular metabolism since it maintains the concentration of sodium and potassium ions in normal values for the cell where sodium is maintained extracellularly and potassium intracellularly. One ATP is always hydrolyzed for every 3 Na + that are extracted and every two K + that are introduced and in turn while maintaining the concentrations, a lot of energy is consumed. In cases of cellular injury or where ATP production is diminished, the pump does not have sufficient operating capacity. It's a type of active transport.
