The catalytic efficiency of two different enzymes can be compared by the
-
- formation of the product
- pH optimum value
- Km value
- molecular size of the enzyme
Correct Option: C
Km (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. Km is inversely proportional to affinity of enzyme far its substrate.
