Vedclass · Answer

(C) The digestive system performs two main types of processes to break down complex food substances into simpler absorbable forms:$1$. Mechanical processes: These include mastication (chewing) in the mouth,churning in the stomach,and peristalsis in the alimentary canal,which physically break down food into smaller particles.$2$. Biochemical processes: These involve the action of various digestive enzymes (e.g.,amylase,pepsin,lipase) that chemically break down complex macromolecules like carbohydrates,proteins,and fats into their simpler monomeric forms (glucose,amino acids,fatty acids).Therefore,both mechanical and biochemical processes are essential for digestion.
