At 1 AM, a healthy squid giant axon is placed in a bath of normal squid physiological extracellular saline and is internally perfused 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, there is a change in the
A. intracellular perfusion fluid so that its concentration of potassium ion is decreased. This will cause an increase in the resting membrane voltage.
B. extracellular saline so that its concentration of potassium ion is decreased. This will cause a increase in the Nernst equilibrium potential for potassium ion.
C. intracellular perfusion fluid so that its concentration of potassium ion is increased. This will cause a decrease in the Nernst equilibrium potential for potassium ion.
