Cellular respiration has 4 steps: Glycolysis (this the first step in cell respiration, which is the conversion of glucose/sugar to pyruvate) Pyruvate Oxidation (the next step in converting glucose to ATP, which entails converting pyruvate to acetyl-CoA, to enable ATP to be manufactured) Krebs Cycle (this uses acetyl-CoA to generate a pool of chemical energy substances, ATP, NADH, FADH2) Oxidative Phosphorylation (the last step in ATP production, where the mitochondria use the chemicals produced in the Krebs cycle to pump out ATP)
