Chapter 41, Problem 7TYK
Why does salivary amylase not hydrolyze starch in the duodenum?
- a. Starch is completely hydrolyzed into maltose in the oral cavity.
- b. The acid pH of the stomach denatures salivary amylase, and pepsin begins hydrolyzing it.
- c. Salivary amylase is produced by salivary glands and never leaves the oral cavity.
- d. Pancreatic amylase is a more effective enzyme in the pH of the duodenum.
