What is the difference between the membrane potential in a normal cell and an excitable cell?

Why is the resting membrane potential negative? Shouldn't it be positive as cells move in and out positive ions

The primary difference between an EPSP and an IPSP is the a) overall speed b) degree of effect c) direction of membrane polarization d) ease of elicitation

8) The diffusion of K+ out of the cell makes the inside of the cell less positive, or more negative, and acts to restore the original resting membrane potential. This process is called: a) depolarization  b) hyperpolarization c) repolarization

How does the movement of ICF K+ ions down its concentration gradient affect membrane potential?

which of the following statements is false with regard to cell electrical impulses? a. an impulse begins when chloride ions are allowed to rush inside the cell b. depolarization is when the relative charges across the membrane have switched due to ions crossing the membrane c. repolarization refers only to the relative charges across the membrane being restored, even when the ion balance is not returned to normal yet d. ionic balance is brought back to resting potential by the sodium-potassium pumps
