EnergyMetabolism/NutrientAndEnergy/EnergyMetabolismWithOxygen

Large amount of chemical energy remain in the degradation products of energy metabolism without use of oxygen. This means that there are many conncections left. Next, the cell uses oxygen and further degrades the products without using oxygen by removing connections and energy. In this step, many conncections are removed and many small substances, such as carbon dioxide (CO₂) and water (H₂O) are the degradation products.

oxygen is used and a large amount of energy is removed. At this metabolism, large amount of molecules are removed and many small degradation product are smallsmall dioxide(CO2)and water(H2O).
