The catalytic efficiency of two different enzymes can be compared by the

Options

A. formation of the product
B. pH optimum value
C. `K_(m)`value
D. molecular size of the enzyme

Answer

C

Explanation

`K_(m)`- Michaelis-Menten constant is defined as substrate concentration at which reaction velocity ot enzyme Cdtalysed reaction `(V_(0))` is half of the maxi1num velocity of this reaction`(V_(max)),(i.e. K_(M)=(1)//(2) V_(max)).K_(m)` can vary greatly from enzyme to eynzyme and even for the different substrates of the same enzyrne.
