The main events occurring in the small intestine are: i) Emulsification of fat globules by bile juice. ii) Breaking down of proteins into amino acids by trypsin. iii) Breaking down of emulsified fats into fatty acids and glycerol by lipase. iv) Breaking down of carbohydrates (starch) into glucose by pancreatic amylase.

What are the two processes of digestion?

Digestion is a form of catabolism or breaking down of substances that involves two separate processes: mechanical digestion and chemical digestion. Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion.
