Enzymes

Enzymes have much the same job as catalysts.
They speed up biological reactions and like enzymes they are not used up in the process.
They are specific to a certain kind of reaction.
They work harder the higher the temperature but have a cut off point like catalysts.
Because enzymes are specific, different ones work best at different pHs.
