Detailed explanation-1: -Enzymes are proteins that help speed up chemical reactions in our bodies. Enzymes are essential for digestion, liver function and much more. Too much or too little of a certain enzyme can cause health problems. Enzymes in our blood can also help healthcare providers check for injuries and diseases.
Detailed explanation-2: -A substance that speeds up a chemical reaction-without being a reactant-is called a catalyst.
Detailed explanation-3: -Enzymes are proteins which catalyze, or ‘speed up’, chemical reactions.
Detailed explanation-4: -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.
