Studied by 4 peopleWhat are enzymes?
Catalysts produced by living things
What is a catalyst?
Something that increases a chemical reaction without being consumed
What does raising temperature do to a reaction?
Speeds it up
What is an active site?
The part of the enzyme that joins to the substrate to catalyse the reaction
What is the lock and key mechanism?
The substrates shape has to match the shape of the active site or the reaction will not be catalysed
What are the 3 things that affect the rate of reaction?
Temperature
pH
Substrate concentration
What are the 3 types of enzyme?
Protease
Lipase
Amylase
What enzyme breaks down fat?
Lipase
What enzyme breaks down starch?
Amylase
What enzyme breaks down proteins?
Protease
What is the meaning of optimum temperature?
Where the enzyme is most active
Why does the rate of reaction stop increasing at a point?
All the active sites become full
