Question
Which of the following vitamins is required for the citric acid cycle?
- Thiamine
- Biotin
- Vitamin E
- All of the above
Hint:
Vitamins thiamine (vitamin B1) work as coenzymes in this cycle.
The correct answer is: Thiamine
- In the citric acid cycle, vitamins like riboflavin, niacin, and thiamine function as coenzymes, and pantothenic acid makes up the CoA portion of acetyl-CoA.
- Aconitase is inhibited by fluoroacetate, alpha-ketoglutarate by arsenite, and succinate dehydrogenase by malonate.
