Question

What are the results of the chemical digestion of carbohydrates, proteins and fats? Does this digestion occur in the mouth, stomach and/or the small intestine?

Answer 1

Answer:

Chemical digestion is the process of breaking down macromolecules and absorbing nutrients and vitamins.

Explanation:

• Chemical digestion of carbohydrates, proteins, and fats begins in the mouth. Salivary amylase helps in the break down of polysaccharides into disaccharides or monosaccharides and lingual lipase helps in breaking down fats and triglycerides into monoglycerides.
• In the stomach, pepsin comes into action by breaking down proteins into amino acids and gastric lipase breaks down fats.
• In the small intestine, release many enzymes like sucrase and lactase for digestion of sugar and lactose.
• All of the nutrients, vitamins, and minerals get absorbed in the large intestine.
