Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Alpha-amylase, an enzyme present in saliva, breaks down starch. Which food does it help to digest?
A
milk
B
candy
C
steak
D
potato
Explanation: 

Detailed explanation-1: -Amylase is present in the saliva of humans and some other mammals, where it begins the chemical process of digestion. Foods that contain large amounts of starch but little sugar, such as rice and potatoes, may acquire a slightly sweet taste as they are chewed because amylase degrades some of their starch into sugar.

Detailed explanation-2: -Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb.

Detailed explanation-3: -Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase.

Detailed explanation-4: -Potatoes and apples contain amylase in varying amounts. Amylase in potatoes and apples helps the organism to breakdown starch, a complex carbohydrate into simple sugars. Amylase activity contributes to less grainy and sweeter fruits and vegetables.

Detailed explanation-5: -Alpha-amylase begins the process of starch digestion. It takes starch chains and breaks them into smaller pieces with two or three glucose units.
