Which of the choices below is not a fate of carbohydrate taken into the body?
(a) lipogenesis
(b) glycogenesis
(c) amino acid synthesis
(d) conversion to a nucleic acid
(e) ATP production
The correct answer is (d) conversion to a nucleic acid.
Carbohydrates are the organic compounds which are a potent source of energy. The digestion of carbohydrates results in simple sugars like glucose which yield energy in the form of adenosise triphosphate (ATP). Around 36-38 ATP molcules are produced by a single glucose molecule.
Lipogenesis is defined as the metabolic formation of fats. Liver is involved in the conversion of the stored sugars like glycogen into triglycerides. Thus, lipogenesis is one of the fates of carbohydrates in our body.
Glycogenesis is the formation of glycogen from the sugars. When excess of carbohydrates are consumed than that is required by the body, they are converted into glycogen and stored in the liver. Thus, Glycogenesis is also one of the fates of carbohydrates in our body.
Amino acid synthesis is a set of biochemical pathways in which amino acids are synthesized from biomolecules like carbohydrates and other. Pyruvate, which is the end product of glycolysis is involved in the sythesis of amino acids like valine, alanine and leucine.
Nucleic acids are the polymers of nucleotides made up of a nitrogenous base, a phoshate and a sugar. Hence, carbohydrates cannot be converted into nucleic acids and it is not a fate of carbohydrate taken into the body.
