<prompt> Which pathway can use propionic acid:GlycolysisGluconeogenesisGlycogenolysisGlycogenesis  <response>: Ans. B. GluconeogenesisOdd chain fatty acids can act as substrates for gluconeogenesis, since Propionyl CoA-the product of their oxidation can enter TCA cycle through formation of Succinyl CoA, hence can contribute towards Glucose production.
