Which consequence results when an enzyme weakens substrate binding, altering its Michaelis constant?

A)Increased catalytic competence ensues
B)Reduced product inhibition occurs
C)Decreased energy barrier height
D)Substrate turnover rate lessens

💡 Explanation

Decreased substrate binding increases the Km (Michaelis constant), impairing the enzyme's ability to reach maximal velocity because the substrate binds less effectively, therefore, turnover lessens rather than catalysis speeding up if correct orientation does not happen.
