dentify the correct statement regarding enzymes.
(1)
Enzymes are specific biological catalysts that can normally function at very high temperatures .
(2)
Enzymes are normally heterogeneous catalysts that are very specific in action.
(3)
Enzymes are specific biological catalysts that cannot be poisoned.
(4)
Enzymes are specific biological catalysts that possess well defined active sites.
1) 2) 3)
Enzymes are specific biological catalysts that possess well defined active sites.
Explanation: Normal optimum temperature of enzymes is between 25°C to 40°C. Hence (a) is false. Enzymes are normally homogeneous catalysts that can be poisoned. Enzymes have well defined active sites and their actions are specific in nature.
