Aminolevulinate dehydratase (ALAD ) is an enzyme that relies on zinc as a coenzyme. A zinc ion binds to the ALAD active site, wh
slavikrds [6]

Answer:

The correct option is C. It changes the three-dimensional structure of the active site so that ALAD is no longer compatible with its substrate.

Explanation:

Co-factors are molecules that are required by an enzyme to perform its function of catalysis. If a wrong co-factor binds to the enzyme then it will change the three-dimensional structure of the enzyme and the substrate will no longer fit into the enzyme. Hence, Option C is the best choice that explains the inhibition of ALAD.

Other options are false because :

Option A: The wrong co factor will not affect the substrate nor will it make it compatible for ALAD's active site.

Option B:  The wrong factor doesn't change the amino acid sequence of the protein or enzyme, rather it changes the three dimensional structure of the enzyme.

Option D : The wrong co factor won't allow the reaction to proceed at a faster rate, rather it will inhibit the reaction.
