Biological molecules (proteins) which catalyze a biochemical reaction and remain unchanged after completion of reaction are called_____________________?
Correct answer: D. Enzymes
- A. Cofactor
- B. Coenzymes
- C. Activator
- D. Enzymes
Explanation
Enzymes are biological catalysts, usually proteins, that speed biochemical reactions by lowering activation energy and remain chemically unchanged after the reaction. The likely alternative is coenzyme, but a coenzyme is a non-protein helper molecule, not the complete protein catalyst itself.

About Characteristics of Enzymes
Enzymes are globular biological catalysts that lower activation energy without being consumed, usually showing specificity for particular substrates. Questions cover active sites, enzyme substrate complexes, the lock and key and induced fit models, intracellular and extracellular action, and the effects of denaturation, while distinguishing enzymes from non biological catalysts.
