The function of enzymes in the living system is to
1 transport oxygen
2 provide energy
3 provide immunity
4 catalyse biochemical reactions
Explanation:
The function of enzymes in the living system is to catalyse biochemical reactions which occure in living systems. e.g., invertase, pepsin, amylase. (polymer) (monomer) (polymer) (monomer)

How do enzyme catalyse the reaction?
1 By holding the substrate molecule for chemical reaction
2 By providing functional groups which will attack the substrate to carry out chemical reaction
3 Both (1) & (2)
4 Neither (1) nor (2)
Explanation:
In their catalytic activity, enzymes perform two major functions: (i) The first function of an enzyme is to hold the substrate for a chemical reaction. Active sites of enzymes hold the substrate molecule in a suitable position, so that it can be attacked by the reagent effectively. (ii) The second function of an enzyme is to provide functional groups that will attack the substrate and carry out chemical reaction.

Assertion : Competitive inhibitors compete with natural substrate for their attachment on the active sites of enzymes. Reason : In competitive inhibition, inhibitor binds to the allosteric site of the enzyme.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Non-competitive inhibitor inhibits the catalytic activity by binding the enzyme at allosteric site.

Assertion : Non-competitive inhibitor inhibits the catalytic activity of enzyme by binding with its active site. Reason : Non-competitive inhibitor changes the shape of the active site in such a way that substrate can't recognise it.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
