These are diagrams I use for teaching cellular respiration. There are four diagrams (you get a black and white set and a colored set). The diagrams can be projected as you present your lesson. There also is a set of partially complete diagrams that students can use for note taking, as a review activity, or as a possible quiz. These are not for junior high life science. These are for high school biology/advanced biology. A-Thom-ic Science.
