Cellular Respiration and Rigor Mortis Cellular respiration is a metabolic process where the body uses organic molecules to produce energy. One of the greatest energy sources that our body uses is glucose. In cellular respiration glucose is broken down‚ and the energy from those bonds is used to create adenosine triphosphate (ATP). There are two types of respiration: aerobic and anaerobic. In aerobic respiration there are 3 main steps: Glycolysis‚ Krebs Cycle (Citric Acid Cycle)‚ and Oxidative Phosphorylation
