Cat As Ion......

a: Ion channel ~
b: cat door

What: "The ion channel is like a cat door. It allows the ions to move through the membrane by making a sort of tunnel. My cats' door can be set to open in both directions, only one direction, or stay closed. So I can keep them on either side of the big door. Ion channels can be like this too. They may always be open, but it is more likely that they will only be open at certain times."
