Enzymes involved in digestion: amylase, protease, lipase

• Which enzyme is responsible for digesting fats?

  Lipase
• Which enzyme is responsible for digesting proteins?

  Protease
• What is the name of the enzyme that digests lactase in the pancreas?

  Lactase
• Which enzyme is responsible for digesting carbohydrates?

  Amylase
• What is the role of pancreatic amylase?

  To further break down starch in the small intestine
• What is the name of the enzyme that digests maltose in the pancreas?

  Maltose
• What are the key digestive enzymes found in the pancreas and their functions?

  • Maltose: Digests maltose
  • Exopepsidase: Removes amino acids until dipeptides are left
  • Nuclease: Digests DNA & RNA
  • Dipepsidase: Digests dipeptides into single amino acids
  • Lactase: Digests lactase
  • Sucrase: Digests sucrose
• What is the name of the enzyme that digests dipeptides into single amino acids in the pancreas?

  Dipepsidase
• What does protease do in the digestive process?

  It breaks down proteins into amino acids
• What is the name of the enzyme that digests sucrose in the pancreas?

  Sucrase
• What does protease break down?

  Protein chains
• What does amylase break down?

  Carbohydrate chains
• What are the three main digestive enzymes?

  Amylase, protease, and lipase
• What does lipase break down?

  Fat molecules
• What components do the digestive enzymes help the body absorb?

  Necessary components for energy and growth
• What type of enzyme is amylase?

  Carbohydrate-digesting enzyme
• How do digestive enzymes aid in digestion?

  • Break down food molecules step-by-step
  • Convert food into smaller components
  • Facilitate absorption of nutrients
• How do digestive enzymes function in the body?

  They act as biological catalysts
• How does amylase affect the taste of bread?

  It makes bread taste sweeter
• Where is saliva amylase found?

  In your mouth
• What are enzymes?

  Biological catalysts
• What happens when you chew bread in relation to amylase?

  Saliva amylase starts changing starch into sugars
• What is the role of enzymes in digestion?

  They speed up chemical reactions
• How do enzymes affect activation energy?

  They lower the activation energy
• What is the role of proteases in the stomach and small intestine?

  They play essential roles in protein digestion
• What is the function of the enzyme Exopepsidase in the pancreas?

  Removes amino acids until dipeptides are left
• What is the name of the enzyme that digests DNA and RNA in the pancreas?

  Nuclease
• How do proteases function in protein digestion?

  They act as biological scissors, cutting protein chains
• What are the functions of the enzymes in the small intestine?

  • Lipase: Digests triglycerides in fatty acid + glycerol
  • Amylase: Digests starch into maltose
  • Phospholipase: Digests phospholipids into fatty acids + glycerol & phosphate group
  • Insulin: Regulates glucose in blood
  • Endopepsidase: Digests proteins into short polypeptides
• Which proteases are found in the pancreas?

  Trypsin and chymotrypsin
• What role does pepsin play in digestion?

  It starts digesting proteins from meat
• What is lipase?

  An enzyme that breaks down fats
• What does lipase break fats down into?

  Fatty acids and glycerol
• Why is the action of amylase important for sugar absorption?

  It helps the body absorb sugars more easily
• What is the role of lipase in digestion?

  It breaks down fats into fatty acids and glycerol
• What is the digestive pathway for proteins in the body?

  • Begins in the mouth (no proteases)
  • Continues in the stomach (pepsin)
  • Further digestion in the small intestine (trypsin and chymotrypsin)
• What is the effect of enzymes on food breakdown?

  They allow quick food breakdown
• What do proteases break proteins down into?

  Peptides and amino acids
• What happens if digestive enzymes do not function properly?

  Nutrients may not be absorbed efficiently
• What are the functions of the three main digestive enzymes?

  • Amylase: Breaks down carbohydrate chains
  • Protease: Breaks down protein chains
  • Lipase: Breaks down fat molecules
