Non-protein part co-factor includes organic & metallic organic molecule & sometimes _ .
Correct answer: C. Coenzyme
- A. Vitamins
- B. DNA
- C. Coenzyme
- D. None
Explanation
Option C is correct.Enzymes are proteins which help to catalyze the biochemical reaction. The enzyme has a protein part which is not active is known as apoenzyme. It gets activated by the addition of an organic or inorganic cofactor. The holoenzyme is defined as apoenzyme in combination with the cofactor.A cofactor is a non-protein part of the enzyme. It can be metal ions or the organic chemical. The cofactors which are organic chemicals are known as a coenzyme. These are loosely attached to the apoenzyme. The tightly bound coenzymes are the prosthetic group.

About Enzymes as Biocatalysts
Enzymes are protein or RNA biocatalysts that lower activation energy without being consumed, and their active sites bind specific substrates. The topic covers the lock and key and induced fit models, effects of temperature, pH and substrate concentration, cofactors, enzyme specificity, and competitive versus non-competitive inhibition.
