Enzymes: Biological Catalysts

Introduction Enzymes are called biocatalysts. (Ahmed) These enzymes bind to the substrate. They have specific substrates that must be combined. The place where the enzyme binds is called the active site. The role of the catalyst is to promote the reaction. All of these can only be achieved through chemical reactions. The energy input for causing a chemical reaction is called activation energy. This is the process of promoting the reaction. The enzyme acts like a catalyst and is not accelerated by the reaction.

Structure of enzyme: Biocatalyst made of protein. They accelerate the chemical reaction by providing a path of lower activation energy. As active sites are molded around the substrate, stretched and twisted, they reduce this activation energy. The enzyme is a water soluble globular protein. The shape of the enzyme and active site is determined by the genetic code. The genetic code consists of bases (AT CG). Three bases (codons) encode amino acids whose base sequence determines the order of amino acids (primary structure). The polypeptide chain is then folded and retained by the H bond and then further folded to form a tertiary structure that shapes H bonds, ionic crosslinks and optionally disulfide bridges.

Enzyme / Enzyme / mz / is a polymeric biocatalyst. Enzymes promote chemical reactions. Molecules on which enzymes can act are called substrates and enzymes convert substrates into different molecules called products. Almost all metabolic processes within the cell require that enzyme catalysis occur at a rate fast enough to sustain life. The 8.1 metabolic pathway depends on enzymes that catalyze various steps. Enzyme studies are known as enzymology and recently they have developed a new field of pseudoenzymatic analysis, recognizing that some enzymes lose the ability to undergo biocatalysis during evolution.
