1

What is an enzyme made of?

Protein

2

What is an enzyme?

A biological catalyst

3

What does a biological catalyst do?

It speeds up a reaction without using itself up

4

Can enzymes catalyse the same reaction again after they catalyse it the first time?

Yes

5

Suggest a few reactions that enzymes help with in your body

They build larger molecules from small ones, such as in protein synthesis.
They break down larger molecules into smaller ones, such as in digestion.

6

What is the molecule that binds to an enzyme called?

Substrate

7

What is the active site?

The place where enzymes and substrates bond together

8

How many different molecules can enzymes bind to?

1

9

What is the name of the hypothesis used to explain the bonding of enzymes?

The lock and key hypothesis

10

What is formed when a substrate and an enzyme is formed?

An enzyme-substrate complex is formed

11

How do enzymes catalyse reactions?

The substrate bonds with the enzyme, which does the reaction quickly and then releases the substrate
