What are enzymes used as?

Enzymes works like catalysts. What does a catalyst do?

Enzymes ______ the activation energy, this means that enzyme reactions can take place at a _______ temperature. This means there is a __________ rate of reaction.

What is formed when a substrate fits into an enzymes active site?

Describe the Lock and Key Model

Describe the Induced fit model

In the induced fit model, the enzyme molds around the substrate, putting strain on it, what does this achieve?

Complete the sentence:

Enzyme properties relate to their....

If the tertiary structure of an enzyme is changed, what will this consequently change and what does this mean about the rate of reaction?

Name two factors that could change the tertiary structure of an enzyme

Draw a graph/enthalpy diagram showing how using an enzyme as a biological catalyst reduces the activation energy in an reaction
