Question

Salivary amylase enzymatically breaks down glucose in the oral cavity. true or false

Answer 1

Answer:

FALSE

Explanation:

Digestion begins in the oral cavity when food enters in contact with the salivary amylase, the principal enzyme in saliva. Carbohydrates in the form of starches (like potatoes, rice, or pasta) are hydrolized from polysaccharides into disaccharides, amylose and amylopectin are hydrolyzed into smaller chains of glucose (dextrins and maltose). This step in the digestion of sugars is limited due to the brief exposure time of the food to the enzyme.

Therefore we can conclude that the answer is FALSE because salivary amylase enzymatically breaks down polysaccharides into disaccharides, glucose is not broken down at this point.
