Bile, along with the enzyme lipase, breaks down fat while the enzyme nuclease breaks down nucleic acids and mixed enzymes, such as trypsins and peptidases, break down the proteins. These substances are called by hormones which act base on stimuli received, such as the food in the duodenum. submergence also occurs in the small intestine because of its large wrick up athletic field.
