The diagram below shows a metabolic pathway that is controlled by end product inhibition. For Substance 4 to bring about end product inhibition, with which of the following would it interact?

• Substance 1

• Substance 3

• Enzyme 1

• Enzyme 3

The change in shape of the active site of an enzyme, when its substrate binds, is called...

• specificity

• induced fit

• activation

• inhibition

This is high between active site and substrate and low between active site and product

• lowers activation energy

• induced fit

• affinity

Which type of inhibition involves an inhibitor with a similar shape to the substrate?
