Why is the sodium-potassium pump indirectly important to the ac-tion potential and to maintaining the resting membrane potential?

Describe leak ion channels and gated ion channels. Howare they responsible for the permeability of a restingversus a stimulated plasma membrane?

Describe two things that contribute to the resting membrane potential

There are differences in Na+, K+, and Cl- ion concentrations across the membrane.  Knowing that ions like to flow down their respective concentration gradients explain how the movement of Cl- and K+ ions can result in membrane hyperpolarization.

Match each type of membrane potential (resting, threshold, graded, or action) to its definition: a) The membrane potential at which voltage gated sodium channels open. b) The membrane potential that triggers the action potential. c) Change in membrane potential that may or may not reach threshold and that may be depolarizing or hyperpolarizing. d) Rapid, strong depolarization followed by immediate repolarization. This potential is self-renewing if the right ion channels are nearby.

What accounts for the resting membrane potential seen inunstimulated nerve and muscle cells?

What happens to the membrane potential when Na+/K+ pump is active?

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

What is the most important thing, i.e. what has the biggest impact of determining the resting membrane potential of a cell?

What does the sodium-potassium pump do to reset and maintain resting potential? Inwhat sense is this an active transport mechanism?
