During Cellular Respiration, the body intakes Oxygen and Glucose molecules and converts it into ATP (adenozinetriphosphate) our bodies primary energy source. Cellular Respiration is broken down into 4 different tiers which in turn support several of their own steps in order to occur. The steps in order include Glycolysis, Pyruvate Oxidation, Kreb's Cycle and the Electron Transport Chain, the accumulance of the steps is known as an Aerobic Respiration, or, Mitochondrial Respiration.
