Identify the correct statement regarding enzymes:
Options
- Aenzymes are specific biological catalysts that cannot be poisoned
- Benzymes are specific biological catalysts that possess well defined active sites.
- Cenzymes are specific biological catalysts than can normally function at very high temperatures (T – 1000K).
- Denzymes are normally heterogeneous catalysts that are very specific in their action
Correct answer
B. enzymes are specific biological catalysts that possess well defined active sites.
Step-by-step solution
Normal optimum temperature of enzymes is between 2 5 o C to 4 0 o C . Enzymes have well defined active sites and their actions are specific in nature. The are also known as biological catalysts and can be poisoned also. Here only option (b) is correct while rest are incorrect.
