Which of the Following is Not a Function of the Plasma

Question

Which of the following is not a function of the plasma membrane proton pump?
A)hydrolyzes ATP
B)produces a proton gradient
C)generates a membrane potential
D)equalizes the charge on each side of a membrane
E)stores potential energy on one side of a membrane

Accepted Answer

The plasma membrane proton pump does not equalize the charge on each side of a membrane; instead, it generates a gradient of H+ ions, creating a difference in charge and potential energy between the inside and outside of the cell.
