Enzymatic catalysis is a process where enzymes, which are biological molecules, speed up chemical reactions in living organisms. These proteins lower the activation energy needed for reactions, allowing them to occur more quickly and efficiently. Enzymes are highly specific, meaning each type of enzyme typically catalyzes only one type of reaction or works on a specific substrate. This process is essential for various biological functions, including digestion and metabolism. For example, the enzyme amylase helps break down starches into sugars, while lipase aids in the digestion of fats. Without enzymatic catalysis, many vital processes in the body would occur too slowly to sustain life.
