← ScienceWhich consequence results when enzymatic saturation overcomes substrate concentration?
A)Decreased reaction rate is observed✓
B)Michaelis constant approaches zero
C)Enzyme conformational changes are induced
D)Reaction equilibrium point will shift
💡 Explanation
A decreased reaction rate is observed because, beyond saturation, further increases in substrate will not affect the reaction velocity. This is due to enzyme active sites becoming fully occupied reflecting enzyme kinetics, therefore the reaction rate decreases relative to substrate, rather than achieving zero Michaelis constant or equilibrium shifts.
