Digestion (P1C6) Flashcards
What are the digestive enzymes?
The three digestive enzymes are protease, lipase, amylase and carbohydrase.
What do digestive enzymes do?
Digestive enzymes catalyse the breakdown of large insoluble food.
Where are amylase, protease and lipase all produced?
All 3 of the enzymes are produced from the pancreas.
Where is amylase produced?
Amylase is produced in the salivary glands and the pancreas.
Where is protease produced?
Protease is produced in the stomach, pancreas and small intestine.
Where is lipase produced?
Lipase is produced in the pancreas and small intestine.
What is the purpose of amylase?
Amylase is a carbohydrase that catalyses the breakdown of starch into maltose.
What is the purpose of protease?
Protease catalyses the breakdown of proteins into amino acids.
What is the purpose of lipase?
Lipase catalyses the breakdown of lipids (fats) into fatty acids and glycerol.
Where is bile stored?
Bile is stored in the gall bladder.
What is the purpose of bile? (2)
Bile is alkaline and neutralises hydrochloric acid and also emulsifies fats, increasing their surface area and the rate of enzymes acting on them.
At what pH does lipase act fastest?
Lipase acts fastest at low pHs.
What is the purpose of maltase?
Maltase catalyses the breakdown of maltose into glucose.
Where is maltase produced?
Maltase is produced in the small intestine.
