Choose all that apply [Na*] + [K'] | + + + + This diagram is a drawing of normal conditions that occur in a neuron's axon (not all details are included). This stage that a living neuron would be in, would show that no positive ions are inside the cell current is traveling down the axon the cell will be at rest once the Na ions enter the cell the cell is at rest Na ions are predominantly outside the cel

The membrane potential in animal cells, but not in plants, depends largely on resting K+ channels. How do these channels contribute to the resting membrane potential? Why are these channels considered to be nongated channels? How do these channels achieve selectivity for K+ versus Na+, which is smaller than K+?
