Question

g To answer this question, you may reference the Metabolic Map. Liver and other organ meats contain large quantities of nucleic acids. The digestion of such foods involves RNA hydrolysis, which results in the formation of free ribose. This free ribose can then enter the nonoxidative phase of the pentose phosphate pathway (PPP). Arrange the steps to outline the mechanism by which free ribose can be used as a fuel for glycolysis. Organ meat containing high levels of nucleic acids is consumed. Fructose 6‑phosphate and glyceraldehyde 3‑phosphate enter glycolysis.

Answer 1

• Nucleic acids
• Ribokinase phosphoryles ribose
• Transketolase catalyses the reaction of ribose 5-phosphates with xyluise 5-phosophates
• Transaldoase catalyse the reaction of gkyceraldehyde 3- phosphates and sedoheptulose 7- phosphate.
• Transketolase catalyse the reaction of erythrose 4- phosphates and xylulose 5- phosphates
• Fructose 6 - phosphates and glyceraldehyde 3- phosphates enter glycolysis.
