Put an explanation in order

Practice question

Order these sentences so they explain why a high temperature can stop an enzyme working.

The science has to be right as well as the order. A tidy sequence of false statements is still wrong.

All practice

  1. The rate of product formation falls.

  2. Fewer enzyme-substrate complexes form.

  3. The active site is no longer complementary to the substrate.

  4. The temperature is high enough to break bonds that hold the enzyme’s shape.
