MCQ
Example of coenzyme is:
- A$\mathrm{Zn}^{2+}$
- BLipase
- ✓Vitamin $B$
- DLysine
✓
Answer
Correct option: C.
Vitamin $B$
For some biochemical reactions a substance other than enzymes and substrate is required. These substances are called coenzymes $($organic compounds$)$ or cofactors $($inorganic ions like zinc and copper etc$.).$ The coenzymes usually serve as an acceptor or donor of an atom or a group.
Many coenzymes are derived from vitamins$. B$ group of vitamins forma variety of coenzymes example Nicotinamide adenine dinucleotide $\text{(NAD)}$ which is derived from vitamin niacin, Flavin adenine dinucleotide $\text{(FAD)}$ which is derived from vitamin riboflavin, Coenzyme $A$ which is derived from pantothenate, pyridoxal phosphate which is derived from pyridoxin, Thiamine pyrophosphate which is derived from thiamine etc.
