Detailed explanation-1: -All enzymes are proteins, but the reverse is not true. So, the correct answer is “Option B”. Note: Enzymes are not the only biological catalysts that’s found in our body. Ribozymes are RNA molecules that have the ability to catalyse a chemical reaction.
Detailed explanation-2: -Answer and Explanation: The given statement is true. All enzymes are proteins but all proteins are not enzymes. Enzymes are the proteins that act as biological catalysts or biocatalysts and are required for almost every reaction in the body.
Detailed explanation-3: -Every enzyme consists of a code of the letters “EC” followed by four numbers separated by periods. The first digit defines the general type of reaction catalysed by the enzyme and ranges from one to six. The second figure indicates the subclass. The third figure gives the sub-subclass.
