Question

How do enzymes speed up reactions?

Answer 1

Enzyme:

1. An enzyme is a biological catalyst.
2. It speeds up a reaction by lowering or reducing the activation energy of the reaction.
3. It can increase the rates of both forward and backward reactions.
4. However, it itself does not take part in the reaction.
5. The process by which it increases the rate of a reaction by lowering its activation energy is called catalysis.
