A cofactor made of inorganic ion which is detachable is called__________________?
Correct answer: C. Activator
- A. Prosthetic group
- B. Coenzyme
- C. Activator
- D. Cofactor
Explanation
A detachable inorganic ion that assists enzyme activity is called an activator, such as Mg2+ or Zn2+. A student may choose cofactor because an activator is a type of cofactor, but “cofactor” is the broader term and the question asks for the specific category of detachable inorganic ions.

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.
