The $\text{Km}$ value of the enzyme is the value of the substrate concentration at which the reaction reaches to
1 Zero
2 $2\text{Vmax}$
3 $1/2V\text{max}$
4 $1/4\text{Vmax}$
Explanation:
(c) The concentration of substrate at which velocity of enzymatic action reaches half of its maximum value, is called $\text{Km}$ value or Michaelis constant.

Enzyme that break nucleic acids into nucleotides belongs to which of following class?
1 Oxidoreductases
2 Transferases
3 Hydrolases
4 Lyases
Explanation:
(c) Nucleases, which belong to the class of enzymes called hydrolases, are usually specific in action. Nucleases is an enzyme that cleaves nucleic acids. Hydrolases is one of the six main classes of enzymes that catalyze a hydrolytic cleavage reaction.

Which one of the following statements is incorrect?
1 In competitive inhibition, the inhibitor molecule is not chemically changed by the enzyme.
2 The competitive inhibitor does not affect the rate of breakdown of the enzyme-substrate complex.
3 The presence of the competitive inhibitor decreases the$\text{Km}$ of the enzyme for the substrate.
4 A competitive inhibitor reacts reversibly with the enzyme to form an enzyme- inhibitor complex.
Explanation:
(c) ${{K}_{m}}$ increases but ${{V}_{\text{max }\!\!~\!\!\text{ }}}$ remains the same in competitive inhibition. This is because, on slightly increasing the substrate concentration, the effect of inhibitor is removed.
