How do you speed up a chemical reaction in a test cannot tolerate extreme temperatures, so they rely on catalysts.

the catalysts in cells are enzymes. Enzymes bind specific reactants and help break or form new bonds between then. Enzymes lower the activation energy of a reaction without changing (G) or the final ratio of products to reactants.

What You'll Learn in this Topic

• What enzymes can do to speed up reactions.
• What enzymes cannot do to speed up reactions

Your task is to interview enzymes that want a job catalyzing a reaction in the cell. Use your knowledge of how enzymes work to find the best candidate.
