Enzymes Flashcards
What does amylase break carbohydrates down into
Maltose and glucose
What does protease break proteins down into
Amino acids
What does lipase break down fats into
Glycerol and fatty acids
Where is amylase found
Salivary gland, pancreas and small intestine
Where is protease found
Small intestine and pancreas
Where is lipase found
Pancreas and pancreas
What does lipase digest
Fats
What dies amylase digest
Carbohydrates
What does protease digest
Protein
Substrate
The chemical(s) at the start of a reaction
Active site
The part of the enzyme where the substrate binds
Complementary
When the substrate and active site have shapes that fit together
Lock and key hypothesis (3 marker)
- Enzyme binds to substrate because they are complementary
- so the substrate is broken down into products
- so products are released or enzyme is not changes
What are two things that enzymes do
- Break down large substrates into smaller products
- make large products from small substrates
Facts about enzymes
-They aren’t used up in reactions so they can be reused
-They speed up chemical traction within the body and are often called biological catalysts
-Enzymes are specific to one chemical reaction and won’t work with different substrates
-They are made from protein by ribosomes inside cells
