Detailed explanation-1: -Before starch can enter a cell, it must be broken down into its individual glucose molecules. The glucose molecules can then be transported inside the cell and used to power cellular respiration reactions.
Detailed explanation-2: -The proteins, lipids, and polysaccharides that make up most of the food we eat must be broken down into smaller molecules before our cells can use them-either as a source of energy or as building blocks for other molecules.
Detailed explanation-3: -Starch and glycogen are broken down into glucose by amylase and maltase.
Detailed explanation-4: -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).
