Which of the following statements about protein digestion are true? Check all that apply. ► View Available Hint(s) Pepsin is active only in an acidic environment. Hydrochloric acid in the stomach denatures proteins and activates some enzymes. The tertiary and secondary structures of proteins unfold due to the action of the enzymes in the gut. Most of the hydrolysis of polypeptides takes place in the small intestine. Some proteins are broken down into amino acids by the process of chewing. The primary structure of a protein is destroyed by hydrolysis.
