Question 1 Which of the following statements is true regarding compounds of the TCA cycle resulting from introduction into the TCA cycle of Glutamate labeled in the R group carboxyl carbon transaminated to a-Ketoglutarate and taken through one complete round back to Succinyl CoA? Multiple answers: Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation. SHOW MORE V After one complete round Succinyl CoA will be radioactive. The labeled R group carboxyl of Glutamate will be released as radioactive carbon dioxide. The transfer of Acetyl-CoA to Oxaloacetate will be result in radioactive Citric Acid. d. A possible source of radioactive carbon dioxide is the Isocitrate Dehydrogenase reaction. A possible source of radioactive carbon dioxide is the a-Ketoglutarate Dehydrogenase reaction. No released carbon dioxide is radioactive. If taken through two complete rounds Succinyl CoA produced will be radioactive. The carbon of the resulting citric acid bearing the hydroxyl group is oxidized by a-Ketoglutarate Dehydrogenase. i Both of the - CHz- carbons of the formed Succinate are oxidized by Succinate Dehydrogenase

Nitrogen metabolism

Nitrogen metabolism is the synthesis, utilization or uptake, breakdown, and excretion of nitrogenous compounds in the body. The nitrogen metabolism encompasses nitrogen fixation, biosynthesis, and the breakdown of amino acids, purines, and pyrimidine. Since nitrogen-containing compounds are required for various life processes, nitrogen is an important element of life.
