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: -Enzymes are biological catalysts which speed up the rate of a chemical reaction (i.e. digestion) by lowering activation energy. Enzymes allow digestive processes to therefore occur at body temperatures and at sufficient speeds for survival requirements. More items
