Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Amylase breaks down
A
carbohydrates
B
proteins
C
fats
D
nucleic acids
Explanation: 

Detailed explanation-1: -The end goal of amylase is to break down carbohydrates into simple sugars that the body can use for energy, and this starts in the mouth. As food is chewed and mixed with saliva, amylase starts working to break down food into smaller molecules (1).

Detailed explanation-2: -You begin to digest carbohydrates the minute the food hits your mouth. The saliva secreted from your salivary glands moistens food as it’s chewed. Saliva releases an enzyme called amylase, which begins the breakdown process of the sugars in the carbohydrates you’re eating.

Detailed explanation-3: -Amylase (made in the mouth and pancreas; breaks down complex carbohydrates) Lipase (made in the pancreas; breaks down fats)

Detailed explanation-4: -Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase. Starch comprises a significant portion of the typical human diet for most nationalities.

Detailed explanation-5: -Carbohydrate digestion begins in the mouth where salivary amylase starts the breakdown. After breaking down throughout the digestive system, monosaccharides are absorbed into the bloodstream. As carbohydrates are consumed, the blood sugar levels increase, stimulating the pancreas to secrete insulin.
