The essential chemical components of many coenzymes are

Step-by-step solution

Some of the cofactors, termed coenzymes, consist of small organic molecules, many of which are derived from vitamins. Vitamins themselves are organic molecules that are needed in small amounts in the diets of some higher animals. These molecules serve the same roles in nearly all forms of life, but higher animals lost the capacity to synthesize them in the course of evolution. For instance, whereas E. coli can thrive on glucose and organic salts, human beings require at least 12 vitamins in the diet. The biosynthet
