Question

Identify the correct statement regarding enzymes.

• A. Enzymes are specific biological catalysts that cannot be poisoned
• B. Enzymes are normally heterogeneous catalysts that are very specific in their action
• C. Enzymes are specific biological catalysts that can normally function at very high temperature (T ~ 1000K)
• D. Enzymes are specific biological catalysts that possess no well-defined active sites.

Answer 1

The correct option is A

Enzymes are specific biological catalysts that cannot be poisoned

Option (a)
Enzymes are specific biological catalysts that cannot be poisoned.
They are not necessarily heterogeneous catalysts: those in solution in the cellular medium are homogeneous, those bound to a membrane are heterogeneous.
We have seen they perform best at the temeperature close to our normal body temperature around 310 K. At very high temperatures, they become denatured.
