Question

Three of the following statements about enzymes are correct and one is wrong. The wrong option is, Higher temperature destroys enzymatic activity because proteins are denatured by heat., Enzymes are denatured at high temperature but in certain exceptional organisms they are effective even at temperatures from 80°–90°C., Enzymes lower the activation energy and hasten the enzyme-catalyzed reaction., Most of the enzymes are active intracellular only and gets inactivated under extracellular conditions

All enzymes are proteins. There is some nucleic acid (rRNA) that functions as enzymes, these are called ribozymes. Enzymes get denatured at high temperatures, except enzymes isolated from the thermophilic organisms. Enzymes are highly specific as only a specific group of the substrate can bind to the active site of the enzyme. Enzymes are active both in intracellular and extracellular conditions.
