Alkaliphiles use ________ force in addition to proton motive force to maintain pH.
A) potassium motive
B) sodium motive
C) calcium motive
D) magnesium motive
E) sulfur motive

Question

Quizplus · Accepted Answer

Alkaliphiles use sodium motive force in addition to proton motive force to maintain pH. This is because at high pH values, protons become scarce, and the alkaliphile uses the sodium instead of protons to power ATP synthesis. The sodium motive force is generated by the sodium-dependent transport of solutes, like protons or amino acids, across the membrane.
