Question and Answer

Enzyme, vitamins and hormones can be classified into a single category of biological chemicals, because all of these
(A) Decrease metabolism.
(B) Are conjugated proteins.
(C) Are exclusively synthesized in the body of a living organism as at present.
(D) Help in regulating metabolism.

Answer

Answer: D
Enzymes, vitamins and hormones are critical to the central role of these elements in the metabolism. Some enzymes in addition to the proteinaceous part require an additional organic molecule coenzyme. Most of the coenzymes are derived from vitamins. Hormones are chemically a diverse group. They may be amines or steroids or peptides. The hormones regulate body metabolism over a longer duration and slowly effect the developmental changes during the development of an organism. The main difference between the enzyme (coenzyme) and hormones is the time scale of their operation. Both are similar in their role in regulating body metabolism.
