Enzymes, vitamins and hormones can be classified into a single category of biological chemicals, because all of these:
- enhance oxidative metabolism
- are conjugated proteins
- are exclusively synthesized in the body of a living organism as at present
- help in regulating metabolism
The Correct Option is D
Solution and Explanation
Enzymes facilitate chemical reactions in metabolism, vitamins are essential coenzymes and cofactors that assist enzymes, and hormones are chemical messengers that regulate various metabolic processes in the body.
So, the correct option is (D): help in regulating metabolism

Concepts Used:
Enzymes - Biology
Enzymes are proteins that help accelerate metabolism or the chemical reactions in our bodies. They build some substances and decompose others. All living creatures have enzymes.
Our bodies naturally build enzymes. But enzymes are also in mass produce products and food.
One of the most important roles of enzymes is to succor digestion. The process of turning the food that we eat into energy is called digestion. For instance, there are enzymes in our saliva, pancreas, stomach, and intestines. They decompose fats, proteins, and carbohydrates. Enzymes make use of these nutrients for growth and cell repair.
