An organ or gland may secrete more than one enzyme.(1) salivary glands (serous cells) (2) stomach (chief cells) A. peptidase B. amylase C. nuclease (3) pancreas (acinar cells) (4) small intestine D. lipase E. pepsinogen F. trypsin, chymotrypsin, carboxypeptidase G. sucrase, maltase, lactase

Which of the following statements regarding protein digestion is incorrect? A. The intestinal enzymes trypsin and chymotrypsin continue the chemical breakdown of polypeptides into oligopeptides. B.
