Q. Identify the correct statement regarding enzymes
A) Enzymes are specific biological catalysts that can normally function at very high temperatures ($T\sim 1000\ K)$
B) Enzymes are normally heterogeneous catalysts that are very specific in their action
C) Enzymes are specific biological catalysts that cannot be poisoned
D) Enzymes are specific biological catalysts that possess well defined active sites
