Concept explainers
Interpretation: To determine B-vitamin-containing coenzymes that are needed in the conversion of pyruvate to
Concept introduction: Vitamins are defined as the micronutrients that are needed in the small amount for the proper functioning of the metabolic activities in the organisms.B vitamins function as coenzymes in the metabolic reactions and are involved in glycolysis, glycogenesis, glycogenolysis, gluconeogenesis, and conversion of pyruvate to lactate and
Coenzymes are non-protein organic compounds that are used along with the enzymes and help to carry forward the reaction. Coenzymes cannot perform on their own alone.
Pyruvate is the end product in the glycolysis. The production of the fate of pyruvate varies with the nature of the organism and the cellular conditions. Pyruvate is converted to
