  2. Respiration can be described… At the cellular level – oxygen is used to break down glucose in the production of the high energy compound ATP (occurs in the mitochondria of the cell) Groups: formula for aerobic respiration At the organ level – structures bring air containing oxygen into the body where it can be transferred to the red blood cells.
