In this type of chemical reaction, the starting molecules are called substrates. The enzyme interacts with a substrate, converting it into a new product. Most enzymes are named by combining the name of the substrate with the -ase suffix (e.g., protease, urease).
WebNov 13, 2024 · Enzymes provide an alternative pathway for a reaction, which has a lower activation energy (Ea) – the minimum energy input needed for a reaction to occur and convert the substrates into products. The transition state is a molecular intermediate between the substrate and its product, through which the reaction passes.
