Detailed explanation-1: -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.
Detailed explanation-2: -Hence, all enzymes are proteins but all proteins are not enzymes. Enzymes are known to speed up the rate of the reaction that occurs in the living cells and hence are known as biocatalysts.
Detailed explanation-3: -Enzymes are proteins, and they make a biochemical reaction more likely to proceed by lowering the activation energy of the reaction, thereby making these reactions proceed thousands or even millions of times faster than they would without a catalyst. Enzymes are highly specific to their substrates.
Detailed explanation-4: -Enzymes are mainly globular proteins-protein molecules where the tertiary structure has given the molecule a generally rounded, ball shape (although perhaps a very squashed ball in some cases).
Detailed explanation-5: -Types of Digestive Enzymes Amylase (made in the mouth and pancreas; breaks down complex carbohydrates) Lipase (made in the pancreas; breaks down fats) Protease (made in the pancreas; breaks down proteins)
