Enzyme present in the saliva is_____________?

Correct answer: C. ptyalin

  • A. lipase
  • B. trypsin
  • C. ptyalin
  • D. invertase

Explanation

Ptyalin is the salivary enzyme, also called salivary amylase, and it begins the digestion of starch into smaller carbohydrates in the mouth. Trypsin acts in the small intestine, while lipase mainly digests fats, so students often choose trypsin because it is another well-known digestive enzyme. Invertase is not the standard enzyme identified with saliva.
