Which consequence results when enzyme concentration approaches substrate saturation in a bioreactor?

A)Reaction rate becomes substrate-independent
B)Increased product inhibition destabilizes system
C)Enzyme denaturation risk reduces markedly
D)Increased lag phase lowers product yield

💡 Explanation

Reaction rate plateaus as Michaelis-Menten kinetics dictates, because essentially every enzyme active site is occupied; therefore reactor rate becomes independent of increasing substrate concentration, rather than product inhibition which applies downstream or other constraints which affect startup time.
