Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The digestion of which food molecule by enzymes begins in the mouth?
A
Glucose
B
Protein
C
Starch
D
Fat
Explanation: 

Detailed explanation-1: -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-2: -The digestion of starch begins with salivary amylase, but this activity is much less important than that of pancreatic amylase in the small intestine. Amylase hydrolyzes starch, with the primary end products being maltose, maltotriose, and a-dextrins, although some glucose is also produced.

Detailed explanation-3: -Digestion of starch takes place in the mouth (oral cavity) and in the small intestine. About 40% of starch that is a carbohydrate is partially digested by ptyalin (salivary amylase) while the remaining 60% starch is digested by pancreatic amylase secretion of the pancreas.
