BIO NMDCAT Biological Importance of Water
nmdcat.online June 27, 2026

In a condensation reaction, the removal of a water molecule is essential for the

A. Release of kinetic energy to drive endergonic reactions
B. Formation of covalent bonds between monomers to build polymers
✓
C. Ionization of amino acids to form zwitterions
D. Denaturation of the tertiary structure of a protein

📝 Explanation

Anabolic polymer synthesis (e.g., peptide bond, glycosidic bond, phosphodiester bond) involves the removal of a water molecule (dehydration synthesis). The hydroxyl group is removed from one monomer and a hydrogen from another, forming water and a new covalent bond.
