OH cr nC-labeled glucose at C6 13C-labeled pyruvate at C3 a) When glucose is enriched with C at C6, it will form pyruvate enriched at C3 (above). The labeled Where does the label exist in succinyl-CoA after the 'C acetyl-CoA is processed in the first round of TCA (after a single action by the first four enzymes in TCA). Circle the atom/atoms where the label exists on the molecule below d pyruvate will be converted into 1'C acetyl-CoA and then...

Question 3 Glucose labeled with 14C in C-3 and C-4 is completely converted to acetyl-CoA via glycolysis and the pyruvate dehydrogenase complex. What percentage of the acetyl-CoA molecules formed will be labeled with 14C, and in which position of the acetyl moiety will the 14C label be found? Select the correct answer and explain your reasoning 100% of the acetyl-CoA will be labeled at C-1 (carboxyl). 100% of the acetyl-CoA will be labeled at C-2. 50% of the acetyl-CoA will...

Question: You buy a sample of glucose that has the radioactive carbon-14 (C) isotope at the second position (Carbon #2). All other carbon positions in the glucose molecules have the "C isotope. "C is only a label and does not alter the biochemical behavior of the molecules in which it is found. This glucose sample is mixed with all the enzymes derived from liver cells, which initially contain no other C-labeled chemicals. A) Draw the Haworth structure of glucose and...

Drawing Glycolytic intermediates. Glucose labeled with 14_C at C-1 was incubated with the glycolytic enzymes and necessary cofactors. Draw structures to show the transformation of glucose to two molecules of glyceraldehyde 3-phosphate via the first half of glycolysis, clearly indicating the position of the 14_C label at each step. You do not need to show reaction mechanisms for each reaction.
