Unformatted text preview: , the gradients mentioned in question 4 would both tend to move Na + ___________ the cell. 7. Would the gradients in question 4 promote or oppose the movement of Cl into the cell? a. b. 8. Since the neuron is permeable to Na + as well as K + , the resting membrane potential is not equal to the equilibrium potential for K + , instead it is ___________ mV. 9. What compensates for the movement (leakage) of Na + and K + ions? ______________ 10. What will happen to the resting membrane potential of an excitable cell if: (Write pos or neg to indicate which way the membrane potential would change.) a . extracellular fluid concentration of K + ___________ b . extracellular fluid concentration of K + ___________ c . extracellular fluid concentration of Na + ___________ d . number of passive Na + channels ___________ e. open voltage-gated K + channels ___________ f. open voltage-gated Na + channels ___________...
