Question

The catalytic efficiency of two different enzymes
can be compared by the
(a) formation of the product
(b) pH optimum value
(c) Km value
(d) molecular size of the enzyme

Answer 1

Answer:

The cataylic efficiency of two different enzymes can be compared by the Km value

Answer 2

The catalytic efficiency of different enzymes:

• Option “C” is correct i.e. Km value

• The catalytic efficiency of two different enzymes can be compared by Km value.

• The catalytic competence of two different enzymes can be associated by comparing their Km value or Michaelis Menten constant. The Km is the substrate concentration at which the reaction rate is at half-max. The Km defines the affinity of the enzyme for a substrate molecule. Larger the affinity lower is the Km value and preferably the Vmax can be achieved and vice versa.
