Which statement(s) is/are true about membrane potentials?
A)They are differences in electrical charge on opposite sides of a membrane
B)They are measured in millivolts, with the sign designating the charge on the outside

D)They are always positive during the resting state
E)All of the above statements are true.

Question

Quizplus · Accepted Answer

Membrane potentials are differences in electrical charge across a membrane, typically measured in millivolts, but the sign designates the charge on the inside, not the outside. The ECF and cytosol are not charged as wholes, and resting membrane potentials are usually negative.
