Term
Name the 5 most important properties of enzymes.
Definition
1. They are all proteins
2. Each enzyme controls one particular reaction.
3. They can be used again and again.
4. They are affected by temperature.
5.They are affected by pH
Term
What are the two main typs of enzymes?
Definition
Breakers and Builders.
Term
Give an example when breaker enzymes are used.
Definition
In digestion to break down large molecules into smaller ones.
Term
What do breaker enzymes do?
Definition
They speed up the reaction of breaking large molecules into smaller ones.
Term
What do builder enzymes do?
Definition
They speed up the reaction of joining small molecules together to make large ones.
Term
What are enzymes?
Definition
Enzymes are protein molecules made up of long chains of amino acids.
Term
What is the active site?
Definition
The special shape of an enzyme where the made for the substrate to fit in.
Term
What is a substrate?
Definition
Is the material upon which an enzyme acts.
Term
Whis enzymes can break down crabohytdrates, which proteins, and which fats?
Definition
Carbohydrase, Proteases, and Lipases
Term
What happens when an enzyme is denatured?
Definition
The special shape of the active site breaks down, so the substrate no longer fits.
Term

Definition
It shows the change of the reaction rate depending on the substrate's concentration. From 0 to 2000 the substrate is a limiting factor. From 2000 and on the concentration is not a limiting factor, so the rate is constant.
