Symptoms of a urinary tract infection (UTI) are similar in men, women, and children. Early symptoms and signs are usually easy to recognize and primarily involve pain, discomfort, or burning when trying to urinate.
Protein digestion begins in the stomach with the action of an enzyme that we previously learned about called pepsin. Pepsin is the active protein-digesting enzyme of the stomach. When pepsin acts on the protein molecule, it breaks the bonds that hold the protein molecule together, called peptide bonds.
Be able to describe the digestion of proteins from the time they enter the mouth until they are absorbed through the small intestine wall. 1. Mouth: No chemical digestion occurs only mechanical. 2. Stomach: Pepsin hydrolyzes protein to smaller polypeptides 3.
