Biotin is needed for gluconeogenesis
WebWhich of the following statements concerning biotin and gluconeogenesis is false? a. Biotin is used to add CO2 to certain intermediates in gluconeogenesis. b. CO2 is incorporated into the glucose product. c. Biotin is capable of binding covalently to CO2. d. Biotin helps synthesize an important precursor of phosphoenolpyruvate. e. WebBiotin is a coenzyme for carboxylase enzymes and biotin is required for the synthesis of these molecules: fatty acids, isoleucine, and valine. Biotin is also involved in gluconeogenesis. Once biotin is attached to a molecule, the biotin tag can be used to facilitate affinity purification of that molecule using an immobilized biotin-binding protein.
