Chapter 16 The Citric Acid Cycle 5. Production of acetyl-CoA (activated acetate) Page: 619 Difficulty: 3 Glucose labeled with 14 C 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 14 C, and in which position of the acetyl moiety will the 14 C label be found? A) 100% of the acetyl-CoA will be labeled at C-1 (carboxyl). B) 100% of the acetyl-CoA will be labeled at C-2. C) 50% of the acetyl-CoA will be labeled, all at C-2 (methyl). D) No label will be found in the acetyl-CoA molecules. E) Not enough information is given to answer this question.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
