Enzymes

• What is the role of enzymes in digestion?

  They help break down large molecules.
• How does bile assist in digestion?

  By neutralizing acids and emulsifying fats.
• What are the three main groups of nutrients to break down?

  Carbohydrates, proteins, and fats.
• What enzyme breaks down carbohydrates?

  Amylase.
• What products do carbohydrates break down into?

  Smaller sugars such as maltose.
• Where is amylase produced?

  Salivary glands, pancreas, small intestine.
• What enzyme breaks down proteins?

  Protease.
• What do proteases break proteins down into?

  Amino acids.
• Where are proteases produced?

  Stomach, pancreas, small intestine.
• What are fats also called?

  Lipids.
• What enzyme breaks down fats?

  Lipase.
• What products do lipids break down into?

  Glycerol and fatty acids.
• Where are lipases produced?

  Pancreas and small intestine.
• How can you remember where each enzyme is made?

  • Amylase: pancreas, small intestine, salivary glands
  • Proteases: stomach, pancreas, small intestine
  • Lipases: pancreas, small intestine
• What foods mainly contain carbohydrates?

  Pasta, potatoes, and rice.
• What foods mainly contain proteins?

  Nuts, meats, and beans.
• What foods mainly contain fats?

  Cheese, oils, and chocolate.
• Why are enzymes essential for digestion?

  They break down large molecules into smaller ones.
• What is the significance of soluble molecules in digestion?

  They can be absorbed through the intestinal lining.
• How do the roles of amylase and protease differ in digestion?

  Amylase breaks down carbohydrates, protease breaks down proteins.
• If you consume a meal high in fats, which enzyme will primarily aid in digestion?

  Lipase.
• What would happen if there were no enzymes in digestion?

  Large molecules would not be broken down.
• What is the lock and key theory?

  Every enzyme's active site is complementary to a substrate like a lock and a key
• What is an enzyme?

  A biological catalyst that speeds up the rate of a specific chemical reaction. They are not used up during the reaction and can be used over and over.
• What is carbohydrase?


  An enzyme that breaks down carbohydrates into simple sugars
• What is amylase?


  A type of carbohydrase which breaks down starch
• What is protease?


  An enzyme that breaks down proteins into amino acids
• What is lipase?


  a protein that breaks down lipids (fats) into glycerol and fatty acids
• What is an enzyme?

  a biological catalyst that speeds up specific reactions and is not used up
