A) Enzymes are specific biological catalysts that can normally function at very high temperatures\[(T\tilde{\ }1000K)\]
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
Correct Answer: D
Solution :
Normal optimum temperatus is between
to
hence of enzymee (a) is fa.'se. Similarly (b) and (c) are also false. Enzymes have well defined active sites and their actions are specific in nature.
