The first step of the energy usage for growth is the breakdown process. In order the animal cells can use the food, the food they eat must be broken down into smaller molecules. Step 2 is the process glycosis which <span>converts each </span>molecule<span> of </span>glucose<span> into two smaller molecules of Acetyl CoA. Step 3 is the complete oxydation of acetyl, CoA to H2O.</span>
