Digestive enzymes

• What are the three main biological molecules mentioned in the video?

  Carbohydrates, proteins, and lipids
• Why do we need to break down carbohydrates, proteins, and lipids?

  To absorb smaller soluble molecules into the bloodstream
• What role do enzymes play in the breakdown of biological molecules?

  They speed up the rate of chemical reactions
• What smaller molecules do carbohydrates break down into?

  • Carbohydrates break down into glucose
  • Starch is a polymer of glucose
  • Maltose is two glucose molecules
• What enzyme breaks down starch into maltose?

  Amylase
• What enzyme breaks down maltose into glucose?

  Maltase

• What is the function of bile in lipid digestion?

  It emulsifies lipids to increase surface area
• Where are the enzymes amylase, protease, and lipase produced?

  • Made by the pancreas
  • Made by the small intestine
