The activity of the following enzyme is affected by biotin deficiency____________?
Correct answer: D. Carboxylase
- A. Transketolase
- B. Dehydrogenase
- C. Oxidase
- D. Carboxylase
Explanation
Biotin carries carbon dioxide in carboxylation reactions, so enzymes such as pyruvate carboxylase and acetyl-CoA carboxylase lose activity during biotin deficiency. Transketolase instead depends on thiamine pyrophosphate.
