← ScienceWhich outcome occurs when an inhibited enzyme loses cofactor binding in a metabolic pathway?
A)Decreased flux through pathway results✓
B)Increased feedback inhibition of enzyme
C)Pathway activity shifts towards catabolism
D)Non-competitive inhibitor becomes competitive
💡 Explanation
Loss of cofactor binding eliminates the enzyme's activity due to disruption of the *active site*, therefore decreasing the rate of reaction it catalyzes and causing lower metabolic flux, rather than the other outcomes seen given sufficient binding affinity because cofactor dictates active enzyme status.
