Question: Using only the chemicals you have inside the cell (NaCl) and inside the beaker (sodium acetate), what kind of proteins would you have to introduce in the cellular membrane to make the cell capable of generating some sort of action potentials? Assume you can make these proteins, even if they don't exist in nature. Describe the function they would perform in generating an action potential. Start your answer by explaining in one or two sentences what action potentials are.
