Explain the resting membrane voltage, Biology

Assignment Help:

At 1 AM, a researcher places a healthy squid giant axon in a bath of normal squid physiological extracellular saline and internally perfuses the axon with normal squid intracellular saline. 

Its resting potential at 1:55 AM is -70 millivolts. For this question, ignore any possible effects due to the sodium-potassium pump.  At 2 AM, the researcher changes the

A. Intracellular perfusion fluid so that its concentration of potassium ion is decreased.  This will cause an increase in the Nernst equilibrium potential for potassium ion.

B. Intracellular perfusion fluid so that its concentration of potassium ion is increased. This will cause a decrease in the resting membrane voltage.

C. Extracellular saline so that its concentration of potassium ion is decreased.  This will cause a decrease in the Nernst equilibrium potential for potassium ion.
