The formula for aerobic respiration in animals can be shown by the equation below. A glucose molecule is broken down by enzymes in the presence of oxygen to make carbon dioxide, water, and ATPs. Carbon IV oxide is expelled by the lungs.
C₆H₁₂O₆ + 6O₂ --> 6CO₂ + 6H₂O + 38 ATP
This process occurs in two stages. Glycolysis (that does not require oxygen) occurs in the cytoplasm of cells. The products of the glucose breakdown in this stage is pyruvate, CO₂ and 2 net ATPs. The pyruvate is then converted to acetyl-CoA that enters the second stage called Citric/Krebs cycle. This second stage happens in the mitochondria. The products are CO₂, H₂O and 34 ATPs
