I am making a diagram of a cellular reaction pathway and I'd like the chain of reactions to be surrounded by a large circle, which will of course be the cell membrane. For the life of me though, I cannot figure out how to draw a circle in tikz then move it where I want it. If I put different points than (0,0) as the origin of a circle that doesn't move the circle around.
