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 be labeled, all at C-2 (methyl).
No label will be found in the acetyl-CoA molecules.

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...
