Which of the following coenzymes participate in the reactions of the pyruvate dehydrogenase complex?
a) thiamine pyrophosphate (tpp)
b) lipoic acid (lipoamide)
c) flavin adenine dinucleotide (fad)
d) nicotinamide adenine dinucleotide (nad+)
e) coenzyme a (co-a)

The correct answers are all of them: A) "Thiamine pyrophosphate (TPP)", B) Lipoic acid (lipoamide), C) "Flavin adenine dinucleotide (FAD)", D) "Nicotinamide adenine dinucleotide (NAD+)" and E) "Coenzyme A (Co-A)".

Explanation:

The pyruvate dehydrogenase complex (PDC) is comprised of three enzymes that converts pyruvate into acetyl-CoA by a series of reactions where different coenzymes participate. During the reaction process: Thiamine pyrophosphate (TPP) is used as prosthetic group by Pyruvate dehydrogenase; Lipoic acid (lipoamide) and Coenzyme A (Co-A) are used as prosthetic group by Dihydrolipoyl transacetylase; and Flavin adenine dinucleotide (FAD) and Nicotinamide adenine dinucleotide (NAD+) are used as cofactor by Dihydrolipoyl dehydrogenase.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
