Enzymes +digestion

• Role of enzymes in digestion

  Enzymes help break down large molecules into smaller soluble molecules that can be absorbed through the intestinal lining
• Role of bile in digestion

  Neutralizing acids and emulsifying fats
• Main groups of nutrients

  • Carbohydrates
  • Proteins
  • Fats
• Carbohydrates sources


  • Pasta, potatoes, rice
• Main type of carbohydrate

  Starch
• Carbohydrates breakdown

  1. Enzyme: amylase

  2. Products: smaller sugars such as maltose
• Amylase


  • Made in salivary glands, pancreas, and small intestine
• Proteins sources


  • Nuts, meats, beans
• Proteins breakdown


  1. Enzyme: protease

  2. Products: amino acids
• Protease


  • Made in stomach (pepsin), pancreas, and small intestine
• Fats sources


  • Cheese, oils, chocolate
• Fats breakdown


  1. Enzyme: lipase

  2. Products: glycerol and fatty acids
• Lipase


  • Produced in pancreas and small intestine
• Enzymes production


  All enzymes are made by the pancreas and the small intestine, amylase also by salivary glands, proteases also in the stomach
• How does bile emulsify fats?

  it breaks it down into tiny droplets to give them a bigger surface area for the enzyme to work on therefore making digestion faster
