The catalytic efficiency of two different enzymes can be compared by

Options

  1. Aits Km value.
  2. Bits pH optimum value.
  3. Cthe molecular size of the enzyme.
  4. Dthe formation of the product.

Correct answer

A. its Km value.

Step-by-step solution

Km is the substrate concentration required to reach half the maximum velocity of the reaction. Lower value of Km indicates higher affinity between substrate and the enzyme, thus reaction is fast. The lower value of Km indicates lower affinity and the reaction is slow.
