Membrane potential will affect the directional movement of A)Glucose (C₆H₁₂O₆) B)Cholesterol C)Potassium (K⁺) D)Oxygen (O₂)

Question

Quizplus · Accepted Answer

Membrane potential is the difference in electrical potential between the inside and outside of a cell membrane. Potassium ions (K+) are positively charged and their movement across the membrane is affected by the membrane potential. As the membrane potential becomes more positive (depolarized), potassium ions are driven out of the cell, and as the membrane potential becomes more negative (hyperpolarized), potassium ions are driven into the cell. Therefore, membrane potential affects the directional movement of potassium ions. Glucose, cholesterol, and oxygen are not affected by the membrane potential.
