Consider the cell membrane on a neuron. Explain why its important for the cell membrane of a neuron to sometimes be "open" (permeable) and other times be "closed" (impermeable). As you explain, consider what specific steps or actions would not work well if the cell membrane did not function as normal. (Note: stick to talking about what we covered during class on your page 3 notes. Googling for other answers will not get you credit). help asp someone ​
