Question

Identify the correct statement regarding enzymes:

• A. Enzymes are specific biological catalysts that can normally function at very high temperature
• B. Enzymes are normally heterogeneous catalysts that are very specific in action.
• C. Enzymes are specific biological catalysts that cannot be poisoned
• D. Enzymes are specific biological catalysts that possess well defined active site

Answer 1

The correct option is D Enzymes are specific biological catalysts that possess well defined active site

Enzymes are specific biological catalysts that possess well defined active site.
Enzymes function at physiological temperature $\simeq \left(37{}^{o}C\right)$

Enzymes can be poisoned using suitable inhibitors.

Hence, the correct option is $\text{D}$
