Answer:
option a
Step-by-step explanation:
is turnover number. The turnover number is defined as the number of chemical conversions by single enzymatic site per second.
K_m is Michaelis-Menten constant used in the study of kinetics of enzyme catalyzed reaction.
The relationship between Michaelis-Menten constant and turnover number is as follows:
Here, [S] is substrate concentration, E0 is the initial enzyme concentration and v is the rate of enzyme catalyzed reaction.
Turn over no. (
) is present in nominator while K_m is present in denominator. Therefore for lowest catalytic efficiency, turnover (
) should be low and Michaelis-Menten constant (K_m) should be high.
Therefore, among, given option a is correct.
