1.(3pts) Define resting membrane potential and explain why it is dependent on K 2. (1pt) The most stable (or comfortable) conformation for voltage-gated Na+ channel when the membrane potential is OmV is: (circle one) / CLOSED INACTIVATED 3. (1pt) The most stable (or 'comfortable) conformation for voltage-gated Na+ channe when the membrane/potential is-70mV is: (circle one) OPEN / LoSED INACTIVATED 4. (1pt) The intensity (or 'peak) of the action potential is most dependent on the extracellular concentration of which ion? a. (1pt) Return to resting membrane potential is mort centration of uthiul

Explanation / Answer

1. Resting membrane potential:

Resting membrane potential is the voltage difference across the cell membrane when the cell is at rest. It is a product of the distribution of charged particles.

The typical resting membrane potential of a cell arises from the separation of potassium ions froms intracellular, relatively immobile anions across the membrane of the cell.Because the membrane permeability for potassium is much higher than that for other ions and because of strong chemical gradient for potassium.
