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.

Dr. Jemison, the first woman of color in the world to go into space, served six years as a NASA astronaut. She flew aboard the Space Shuttle Endeavour, STS-47 Spacelab J(apan) mission in September 1992 and was NASA’s first Science Mission Specialist performing experiments in material science, life science and human adaptation to weightlessness.
