The electrical component of an electrochemical gradient is due to:
A)the use of ATP as an energy source to drive primary transport.
B)a greater concentration of positive charges on the side of the membrane with the lowest concentration of protons.
C)a higher pH on the side of the membrane with the highest concentration of protons.
D)a higher pH on the side of the membrane with the lowest concentration of protons.
E)a greater concentration of positive charges on the side of the membrane with the highest concentration of protons.

Question

Quizplus · Accepted Answer

The electrical component of an electrochemical gradient is due to a greater concentration of positive charges on the side of the membrane with the highest concentration of protons. This creates a positive charge imbalance across the membrane, which can drive the movement of charged particles such as ions. Therefore, the best choice is E - a greater concentration of positive charges on the side of the membrane with the highest concentration of protons.
