Why are enzymes necessary for many cellular reactions?

The reactions occur too slow if enzymes are missing.

What is the relationship between enzymes and activation energy?

Enzymes catalyzes a reaction by decreasing activation energy of reaction.

What will happen if an enzyme is added to a reaction?

The reaction rate will increase.
