Which of the following comprises inorganic ions?
Correct answer: B. Activators
- A. Coenzymes
- B. Activators
- C. Prosthetic group
- D. Apoenzyme
Explanation
Activators are inorganic ions that bind to enzymes and play a crucial role in enzyme activity. They are often metal ions like Mg²⁺, Fe²⁺, Cu²⁺, and Zn²⁺. These ions stabilize the enzyme structure or assist in the conversion of substrates to products. In contrast, coenzymes and prosthetic groups are organic and serve different roles in enzymatic reactions. An apoenzyme is the inactive protein form of an enzyme that requires a cofactor, either inorganic or organic, to become active.

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.
