The branch of biology which deals with the study of chemical compounds and the chemical processes in the fliving organisms is called_________________?
Correct answer: B. Biochemistry
- A. Chemistry
- B. Biochemistry
- C. Molocular biology
- D. Both a and b
Explanation
Biochemistry studies the chemical substances and chemical processes occurring in living organisms, including metabolism and the structure of biomolecules. Molecular biology mainly focuses on molecules such as DNA, RNA and proteins and their interactions, so it is narrower than the definition given here. The likely distractor is molecular biology because both fields study biological molecules.

About Classification of Biological Molecules
Biological molecules are classified as carbohydrates, lipids, proteins and nucleic acids, with water, minerals and vitamins also supporting cellular processes. The key distinctions involve their monomers, chemical bonds, structures and functions, including glucose and starch, fatty acids and triglycerides, amino acids and polypeptides, and nucleotides in DNA and RNA.
