Question

Describe what happens to a chemical reaction with or without an enzyme.

Answer 1

Firstly, an enzyme is a chemical substance that speeds up a chemical reaction. This means that a chemical reaction with an enzyme present would be quick or happen at a faster rate.

Enzymes also help the substance undergoing the reaction to not get used up during the process.

However, if the enzyme is absent, the chemical reaction happens very slowly and also the substance undergoing the reaction gets used up during the process.

Answer 2

Without enzymes, many chemical reactions would occur at a much slower rate because the amount of activation energy required would be far greater. When molecules are involved in a chemical reaction, enzymes act as a catalyst for either breaking them down or building them up into more complex molecules.
