Enzyme: Definition, Types, Structure, Functions, & Diagram
2021年11月11日 · Enzymes are protein macromolecules that are necessary to initiate or speed up the rate of chemical reactions in the bodies of living organisms. The molecules on which enzymes act are called substrates, and the substance formed is called the product. They are found in all living cells that vary in type based on the function it performs.

2023年4月24日 · 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.

2024年11月30日 · Enzymes catalyze all aspects of cell metabolism. This includes the digestion of food, in which large nutrient molecules (such as proteins, carbohydrates, and fats) are broken down into smaller molecules; the conservation and transformation of chemical energy; and the construction of cellular macromolecules from smaller precursors.
5.2: Enzymes - Biology LibreTexts
Enzymes are biological catalysts that accelerate chemical reactions by lowering the activation energy. Enzymes are proteins consisting of one or more polypeptide chains. Enzymes have an active site that provides a unique chemical environment, made …
