What is an enzyme?
A protein that acts as a catalyst and speeds up reactions.
What are the main digestive enzymes?
Carbohydrase
Amylase
Protease
Lipase
Where is carbohydrase produced?
Salivary gland
Pancreas
Small intestine
What is carbohydrase's site of action?
Mouth
Small intestine
What does carbohydrase break carbohydrates into?
simple sugars.
What is amylase?
The enzyme that breaks down starch.
What does amylase turn starch into?
glucose
What are digestive enzymes?
Enzymes that convert food into small soluble molecules that can be absorbed in the blood stream.
Where is protease's site of action?
Stomach
Small intestine
What does protease break proteins into?
Amino acids
Where is lipase produced?
Pancreas
Where is proteases site of action?
Small intestine
What does lipase break lipids into.
Glycerol and fatty acids.
How do enzymes work? - lock and theory theory.
Substrate = key
Active site = lock
When the substrate binds to the complementary active site, a chemical reaction happens - breaking bonds in the substrate and making new bonds - releasing the product.
Where is protease produced?
Stomach
Pancreas
Small intestine
What is bile?
A digestive fluid that increases the breakdown of fat by lipase.
Where is bile made?
The liver.
Where is bile stored?
The gall bladder.
What are the features of bile and functions?
Alkaline - neutralises hydrochloric acid from the stomach.
Able to emulsify fat to from small droplets - this increases the surface area.
