    diffusion of K+ out of the neuron through the K+ leak channels. Your answer: When extracellular K+ increases, less of it (K+) goes into the cell. Therefore, the cell depolarizes. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well ...

    increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: By increasing the extrecellular K+ the net diffiusion of K+ out the neuron through the eak channels is reduced. This is caused by the flow of ions following the concentration gradient of traveling...
