← ScienceWhich outcome occurs when substrate active sites saturate?
A)Reaction rate reaches maximum velocity✓
B)Enzyme undergoes irreversible denaturation
C)Substrate inhibition becomes non-competitive
D)Transition state intermediates are destabilized
💡 Explanation
When active sites saturate with substrate, further increases in substrate concentration won't increase the reaction rate because every enzyme molecule is already actively processing substrate via Michaelis-Menten kinetics; therefore, the reaction achieves maximum velocity, rather than denaturation or substrate pathway changes.
