Flashcards in Topic 2.5: Enzymes Deck (5):
1

Define enzyme

An enzyme is a globular protein which acts as a biological catalyst by speeding up the rate of a chemical reaction

2

Define active site

The active site is the region on the surface of the enzyme which binds to the substrate molecule

3

What is the first step of enzyme catalysis?

When a substrate binds to the enzyme’s active site, an enzyme-substrate complex is formed

4

After When a substrate binds to the enzyme’s active site, an enzyme-substrate complex is formed what is the next step of enzyme catalysis?

The enzyme catalyses the conversion of the substrate into product, creating an enzyme-product complex

5

After The enzyme catalyses the conversion of the substrate into product, creating an enzyme-product complex what is the last step of enzyme catalysis?

The enzyme and product then dissociate – as the enzyme was not consumed, it can continue to catalyse further reactions
