<h2>Answer:</h2>
Salivary amylase breaks the chemical bonds of starch to form sugar monomers.
<h3>Explanation:</h3>
- Amylase is one of the digestive enzymes which catalyze the breakdown of starch molecules into its monomers.
- A starch molecule is made of the Glucose molecules which are bonded with each other with glycosidic linkages.
- Salivary glands secrete saliva into the mouth cavity.
- Saliva contains amylase for the digestion of starch are known as salivary amylase.
- Steps in the digestion of sugars start from the action of this enzyme.
