B)membrane potential.
C)electrical gradient.
D)concentration gradient.
E)biological capacitance.

Question

Quizplus · Accepted Answer

The difference in concentration of a specific chemical across a membrane is referred to as a concentration gradient. Option A, electrochemical potential, refers to the combined effects of concentration gradient and membrane potential. Option B, membrane potential, refers to the difference in electrical charge across a membrane. Option C, electrical gradient, refers to the difference in electrical charge across a membrane, and Option E, biological capacitance, is not a commonly used term in cell biology.
