Thiamine deficiency causes decreased energy production because____________?

Correct answer: D. It is co-enzyme for pyruvate dehydrogenase

  • A. It is required for the process of transmination
  • B. It is co-factor in oxidative reduction
  • C. It is co-enzyme for transketolase in pentose phosphate pathway
  • D. It is co-enzyme for pyruvate dehydrogenase

Explanation

Thiamine pyrophosphate is a coenzyme for pyruvate dehydrogenase, allowing pyruvate to enter acetyl-CoA formation and the TCA cycle for energy production. It also supports transketolase, but that pathway is not the main explanation for reduced cellular energy in this context.
