Correct Answer: Pyruvate dehydrogenase
Description: PDH complex consist of 3 Enzymes and 5 Coenzymes
Three enzymes are:
Pyruvate Dehydrogenase bound to Thiamin Diphosphate
Dihydrolipoyl Transacetylase, the prosthetic group is oxidised Lipomide
Dihydrolipoyl Dehydrogenase, contains FAD.
Coenzymes (very important)
Thiamine Diphosphate (TDP)
Lipomide
Coenzyme A
FAD
NAD
