Name the 4 ion channels that contribute to the maintenance of the Resting Potential. Include (i) whether the ion channels use active or passive transport, (ii) which ion moves only by passive transport, (iii) the 3 ions involved in selective permeability, and (iv) the single ion most responsible for maintaining -70 mv across the membrane.

Explain what factors, structures, and ion channels contribute to establishing and maintaining the resting membrane potential. Draw a cell and show all relevant contributors to the resting membrane potential with explanations of how they contribute to establish and maintain the resting membrane potential. What cells have a resting membrane potential? Is it only nerve and muscle (excitable) cells?

Describe the two stages of the Action Potential. Include (i) the names of the ion channels and whether they are active or passive, (ii) which of these ion channels open during the first stage and which open during the second stage, and the direction ions move, and (iii) the value in mV reached during the two stages.

Consider an ion for which there are only passive leakage channels. If the membrane potential is farther from the ion’s Nernst potential, the magnitude of the current associated with that ion will be: a. greater b. smaller c. the same d. none of the above And why?

Explain the reason that the resting potential for neurons is around -70mV. Be sure to include the roles of the K+ and Na+ concentration gradients, electrical forces, passive ion channels and the relative permeabilities of K+ and Na+. Now, say that an alien race was discovered from a distant galaxy. Their cells have a higher concentration of Na+ inside than outside their cells and a higher concentration of K+ outside than inside. If this race’s neurons otherwise had the same...
