WebA cell is protected by its cell membrane. The membrane maintains a constant environment inside the cell and serves a variety of other purposes as well. One of its functions is to transport compounds out of the cell that is harmful as well as allow the entry of nutrients into the cell. The cell membrane has proteins on its surface. WebDescribe how the membrane potential is created: 1) The membrane is more permeable to K+ than Na+ ions; conc of K+ is greater inside cell membrane 2) The Sodium-Potassium Pump actively transports (using ATP) 3Na+ out of the cell and 2K+ into the cell 3) This result in a larger concentration of positive ions outside the axon than there are inside the …
