Neurophysiology of Nerve Impulses ACTIVITY 1 The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative

ACTIVITY 1: THE RESTING MEMBRANE POTENTIAL 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? When the diffusion is greater on one side‚ the other side will slow down. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? There are two potassium’s for every sodium so the increase of potassium will make it more

hyperventilate. The rising pH indicated that the body was expelling CO2 and H+. 7. Did the PCO2 level change during the curse of this run? If so‚ how? Yes‚ the PCO2 level dropped from 40 to 19.7 because the body was getting rid of CO2 by hyperventilating. 8. If you observed an acid/base imbalance during this run‚ how would you expect to renal system to compensate for this condition? The renal system would generate H+ and excrete HCO3- to counteract the respiratory system and lower the pH back to homeostasis
