Question

An enzyme follows Michaelis-Menten kinetics with substrate S. The fraction of the maximum velocity (Vmax) will be observed with the substrate concentration [S] = 4Km is _____ (correct to one decimal place). (Km is Michaelis-Menten constant)

Explanation

Understanding enzyme kinetics reveals substrate binding and catalytic efficiency determine reaction rates. Therefore Option NAT is correct because it reflects active-site specificity and regulation, which underpins key processes in biochemistry.
