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
