B) The methyl (-CH₃) group is eliminated as CO₂.
C) The process occurs in the cytosolic compartment of the cell.
D) The pyruvate dehydrogenase complex uses all of the following as cofactors: NAD⁺, lipoic acid, pyridoxal phosphate (PLP) , and FAD.
E) The reaction is so important to energy production that pyruvate dehydrogenase operates at full speed under all conditions.
