← ScienceWhich outcome results from exceeding enzyme saturation limits?
A)Velocity approaches maximum, then plateaus✓
B)Enzyme degradation begins accelerating rapidly
C)Substrate inhibition increases drastically
D)Cofactor binding affinity drops rapidly
💡 Explanation
Enzyme saturation causes the reaction velocity to plateau because while the substrate concentration is high, all enzyme active sites are occupied, limiting substrate interaction via induced fit, therefore increasing substrate has no additional effect, rather than changing binding affinity.
