WebEnzymes are proteins that help to speed up chemical reactions. They help to speed up these reactions by decreasing the activation energy for these reactions to occur. Enzymes work at very specific pH and temperature. This is because outside of their optimal range for these two conditions enzymes begin to denature, or change shape. Should an ... WebA catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the …

WebEnzymes function to reduce the activation energy required for a chemical reaction to occur. First, the enzyme binds to the substrate and slightly distorts its shape. The change in shape activates the substrate molecule and decreases the total activation energy required for the substrate to be turned into product.

WebJun 8, 2024 · When an enzyme binds its substrate, it forms an enzyme-substrate complex.
