Enzymes Flashcards
What are enzymes made of?
Protein
What are proteins made of?
Amino acids
What makes one protein different to another?
The order of amino acids
State 3 reasons why enzymes are described as biological catalysts
- they are made in living cells
- they speed up chemical reactions
- they are not used up during the reaction
Why are enzymes specific to one substrate?
The shape of the active site of the enzyme is complementary to the shape of the substrate
What does specific mean?
One substate reacts with one substrate
What is the chemical called the enzyme reacts with?
Substate
What is the chemical called that results from a reaction with the enzyme?
Product
What is it called when the substate is broken down into a smaller product?
Degradation reaction
What is it called when a substate is built up into a bigger product?
Synthesis reaction
What are 2 properties of enzymes?
- unchanged by the reaction
2.speed up cellular reactions
What is an example of a enzyme involved in a degradation reaction?
Catalase
What is a enzyme involved in a synthesis reaction?
Phosphoryolase
Where does the reaction occur on a enzyme?
Active site
What is the substate and product of the enzyme amylase?
Substate: Starch
Product: Glucose
