12. The catalytic efficiency of two different enzymes can be compared by the
[2005]
(a) formation of the product
(b) $pH$ optimum value
(c) $K_m$ value
(d) molecular size of the enzyme
Show Answer
Answer : c
Hints & Solutions
(c) $K_m$ (Michealis Menten constant). It is defined as that substrate concentration at which, under optimum conditions, the rate of an enzyme catalysed reaction reaches half the maximum rate. $K_m$ is inversely proportional to affinity of enzyme far its substrate.
