The enzyme which is secreted by salivary gland is?
Correct answer: B. Ptyalin
- A. Pepsin
- B. Ptyalin
- C. Lactalase
- D. Bile
Explanation
Salivary glands secrete ptyalin, also called salivary amylase, which begins the digestion of starch in the mouth. Pepsin acts in the stomach, bile is produced by the liver, and lactase is an intestinal enzyme, so they are not salivary secretions.
