is used to describe the rate-limiting step of catalysis under saturating conditions of substrate
Kcat
The traditional Michaelis-Menten kinetics describes a _____ dependence of V0 on substrate concentration
hyperbolic
The presence of an ______ inhibitor results in a lower apparent Km and Vmax of the enzymatically catalyzed reaction
uncompetitive
____ is a weakening of the signal. This is due to absorption, refraction, and scattering or defraction.
