Question

Saliva hydrolyses starch to?
1. Carbon dioxide and water
2. Fructose
3. Sucrose
4. Glucose

Answer 1

Correct Answer - Option 4 : Glucose

The correct answer is Glucose.

• Salivary amylase or ptyalin is an enzyme that converts starch into maltose, isomaltose, and α-dextrins.
• Lysozyme is an antibacterial agent to kill any bacteria that may have entered via the food in our oral cavity.

•  Salivary amylase is a glucose-polymer cleavage enzyme that is produced by the salivary glands.
  • Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase.
  • Saliva contains the enzyme amylase, also called ptyalin, which is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine.
