enzymes in digestion

• The carbohydrates, proteins, and lipids that we eat are too big
• Why do we need to break down carbohydrates, proteins, and lipids into smaller molecules?

  To absorb them into the bloodstream
• What are enzymes made of?

  Proteins
• Steps in the breakdown of starch

  1️⃣ Starch is broken down by amylase

  2️⃣ Amylase breaks starch into maltose

  3️⃣ Maltose is broken down by maltase

  4️⃣ Glucose is produced
• Enzymes speed up the rate of chemical reactions in the body
• What is the polymer of glucose called?

  Starch
• Match the enzyme with its function:

  Amylase ↔️ Breaks down starch

  Maltase ↔️ Breaks down maltose
• The enzyme amylase breaks starch into maltose
• Proteases break proteins into amino acids
• All amino acids are identical in structure

  False
• What group of enzymes breaks down proteins?

  Proteases
• What specific enzymes are included in the protease group?

  Trypsin and pepsin
• Bile emulsifies lipids to increase their surface area
• What are lipids broken down into by lipases?

  Glycerol and fatty acids
• Bile is an enzyme that breaks down lipids

  False
• Match the enzyme with its source:

  Amylase ↔️ Pancreas and salivary glands

  Proteases ↔️ Pancreas and stomach

  Lipases ↔️ Pancreas and small intestine
• Which organ produces all three types of enzymes?

  Pancreas
• Proteases are also made by the stomach
