Explanation:
Detailed explanation-1: -Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion. The role of chemical digestion is to further degrade the molecular structure of the ingested compounds by digestive enzymes into a form that is absorbable into the bloodstream.
Detailed explanation-2: -In either case, the large polymeric molecules in food are broken down during digestion into their monomer subunits-proteins into amino acids, polysaccharides into sugars, and fats into fatty acids and glycerol-through the action of enzymes.
