The deficiency of thiamine can be identified by measuring the red cell______________?
Correct answer: A. Transketaolase
- A. Transketaolase
- B. Transaldolase
- C. Alpha ketoglutarate dehydrogenase
- D. Pyruvate dehydrogenase

Thiamine pyrophosphate is required by transketolase, and its activity in red blood cells decreases in thiamine deficiency. Measuring transketolase activity, often before and after adding TPP, is therefore useful diagnostically.
