Which of the following is NOT a characteristic of allosteric enzymes?
A)Effectors may show stimulatory or inhibitory activity.
B)They have multiple subunits.
C)They obey Michaelis-Menten kinetics.
D)Binding of 1 subunit impacts binding of substrate to other subunits.

Question

Quizplus · Accepted Answer

Allosteric enzymes do not obey Michaelis-Menten kinetics, as their behavior is regulated by the binding of effector molecules, which can cause conformational changes in the enzyme that impact its activity. This leads to a sigmoidal or "S-shaped" curve when plotting reaction rate versus substrate concentration, rather than the hyperbolic curve seen with Michaelis-Menten enzymes. A, B, and D are all characteristics of allosteric enzymes.
