In class we discussed how the movement of ions can change the membrane potential, and we specifically noted how the movement of sodium and potassium affects this. But there is another ion that is actively involved in changing the membrane potential, and this is chloride, which is a negatively charged ion. Chloride will move into the cell if a channel is opened, so how would that affect the membrane potential?

Please hold up your 4 function basic calculator (all a basic calculator can do is add, subtract multiply and divide) to the camera and hold it there for 5 seconds.   This is the only calculator approved by the math department for this course. Once you have held up your approved calculator, click on true.  Do not click true when you do not have an approved calculator – that is academic dishonesty.  If you do not have the basic calculator, please submit and contact me to reopen once you have the required materials to provide another attempt once the materials are available.
