What best describes the function of the sodium-potassium ion pump?

The Na-K ion pump uses active transport (i.e., energy is expended in the form of ATP) to move Na ions in and K ions out, in order to restore resting membrane potential

The Na-K ion pump uses active transport (i.e., energy is expended in the form of ATP) to move Na ions out and K ions in, in order to restore resting membrane potential

The Na-Ka ion pump uses passive transport (i.e., energy in the form of ATP is spent to move ions), in order to restore resting membrane potential 

The Na-K ion pump relies on passive transport (i.e., ions diffuse in and out along the concentration gradient), in order to restore resting membrane potential

The Na-K ion pump uses active transport (i.e., energy is expended in the form of ATP) to move Na ions out and K ions in, in order to restore resting membrane potential

Which refractory period does this statement best describe: During this period, a new action potential cannot be initiated, no matter how strong the charge of a stimulus signal. 

Relative refractory period

Light refractory period

Sound refractory period

Absolute refractory period

Identify the correct distribution and concentration of ions during resting membrane potential (RMP). 

Equal balance of sodium within the intra- and extracellular space

More sodium in the extracellular space and more potassium in the intracellular space

More sodium in the intracellular space and more potassium in the extracellular space

Equal balance of potassium within the intra- and extracellular space

More sodium in the extracellular space and more potassium in the intracellular space

What is it called when depolarization peaks (aka, there is > 50% of Na in the cell)?

Overshoot

Oh shoot!

Undershoot

Under where? 

Overshoot

This refractory period occurs when the neuron's membrane status has returned to at least 51% restored to resting membrane potential (i.e., between 51-99% restored to RMP).
