Webb1 dec. 2024 · Some proteins function as enzymes. Enzymes are proteins that conduct specific chemical reactions. An enzyme’s job is to provide a site for a chemical reaction and to lower the amount of energy and time it takes for that chemical reaction to happen (Figure \(\PageIndex{1}\)). This is why enzymes are sometimes called catalysts. WebbA catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process.
