The process by which small molecules join together to build a macromolecule, with water released at each link, is called
Correct answer: A. condensation
- A. condensation
- B. hydrolysis
- C. oxidation
- D. photolysis
Explanation
In condensation, an OH from one molecule and an H from the other leave as water while a covalent bond forms, which is how disaccharides, polypeptides and triglycerides are built. Hydrolysis is the reverse: it uses water to break these bonds during digestion.

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.
