Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Starch is digested to ____
A
amino acids
B
sucrose
C
D
Explanation: 

Detailed explanation-1: -Starch digestion involves the breakdown by -amylase to small linear and branched malto-oligosaccharides, which are in turn hydrolyzed to glucose by the mucosal -glucosidases, maltase-glucoamylase (MGAM) and sucrase-isomaltase (SI).

Detailed explanation-2: -During digestion, starches and sugars are broken down both mechanically (e.g. through chewing) and chemically (e.g. by enzymes) into the single units glucose, fructose, and/or galactose, which are absorbed into the blood stream and transported for use as energy throughout the body.

Detailed explanation-3: -Alpha-amylase begins the process of starch digestion. It takes starch chains and breaks them into smaller pieces with two or three glucose units.

Detailed explanation-4: -Starch is a polysaccharide of alpha-glucose monomers joined in long branched or unbranched chains. Starch is an energy storage molecule in plant cells.
