10. Enzymes and Enzyme Action
Biomolecules

185543 Enzymes are denaturated by

1 Low Ph
2 High substrate concentration
3 Low temperature
4 heat
Biomolecules

185544 Given below are two statements :
Statement I : Low temperature preserves the enzyme in a temporarily inactive state whereas high temperature destroys enzymatic activity because proteins are denatured by heat.
Statement II : When the inhibitor closely resembles the substrate in its molecular structure and inhibits the activity of the enzyme, it is known as competitive inhibitor.
In the light of the above statements, choose the correct answer from the options given below :

1 Statement I is false but Statement II is true.
2 Both Statement I and Statement II are true.
3 Both Statement I and Statement II are flase.
4 Statement I is true but statement II is false.
