Cellular respiration is a series of chemical reactions that cells use to break up sugars into a form that the cell can use. Cell respiration requires oxygen to take place. Cellular respiration consists of four stages:1. the breaking down of glucose into molecules (glycolysis)2. the link reaction - this process forms a link between glycolysis and the Krebbs reaction3. Krebbs reaction 4. The electron transport chain
