Apr 24, 2023 · Enzymes are proteins comprised of amino acids linked together in one or more polypeptide chains. This sequence of amino acids in a polypeptide chain is called the primary structure. This, in turn, determines the three-dimensional structure of the enzyme, including the shape of the active site. The secondary structure of a protein describes the ... Enzymes are catalysts. They are usually proteins, though some RNA molecules act as enzymes too. Enzymes lower the activation energy of a reaction - that is the required amount of energy needed for a reaction to occur. They do this by binding to a substrate and holding it in a way that allows the reaction to happen more efficiently. Enzymes are essential for life, and understanding how they catalyze reactions in the body will book your understanding of how our bodies work.Enzymes; Osmosis.
