Which of the following correctly describes a general property of all electrogenic pumps?
pumps sodium out of the cell and potassium into the cell
creates a voltage difference across the membrane
can pump a large variety of solutes across a membrane against their concentration gradient
a cell with an interior that is positively charged relative to the outside of the cell
a cell with a high internal concentration of protons

The correct option is B. Electrogenic pumps creates a voltage difference across the membrane.

Explanation:

Electrogenic pumps are used to travel molecules in and out of a cell by establishing a concentration gradient. Hence, the statement that best describes the property of electrogenic pumps is B.

Other options, like option A is correct but it does not describe the general property of the electrogenic pump.Option C is incorrect because not a large variety of solutes can pass through the membrane.
