NEET · Biology · STD 11 - 9. Biomolecules

The essential chemical components of many coenzymes are

A carbohydrates
B vitamins
C proteins
D nucleic acids

Verified Solution

Answer & Solution

Correct Answer

(B) vitamins

Step-by-step Solution

Detailed explanation

(b) : Coenzyme is the non protein organic group which gets attached to the apoenzyme to form holoenzyme or conjugate enzyme. It helps in removing a product of chemical reaction besides bringing contact between the substrate and the enzyme. Most of the coenzymes are made of water soluble vitamins \(B\) and \(C\), \(e.g.\), thiamine, riboflavin, nicotinamide, pyridoxine.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
