Fate of Carbon in Glycolysis

I am approaching this problem on paper with the "colored pencil method" for following certain labelled carbon atoms (13C). I have done research online to find a clear representation of the cycle, and both glucose and pyruvate structure. I am hoping that you might be able to follow carbon through the glycolytic pathway and explain some of your approaches to doing this. The problems that follow this sequence involve greater tracking skills and logic.

1. In which carbon atoms of pyruvate would 13C be found if glucose metabolized by the glycolytic pathway were labeled with 13C at: (a) C1; (b) C4; (c) C6? (Assume that triose phosphate isomerase is able to equilibrate dihydroxyacetone phosphate and gylceraldehyde- 3-phosphate).

  • Concept map on metabolism

    The fate of pyruvate during anaerobic glycolysis is reduction to lactate. In lactate fermentation, the NADH produced by glycolysis is used to reduce pyruvate to lactic acid. There is one more fate of pyruvate that is alcoholic fermentation.

  • Kreb's Cycle and Energy

    Then, the pyruvate can continue on through the Kreb's cycle to be oxidized to carbon dioxide. In short, lactate formation occurs to produce some NAD+ in the absence of oxygen, so that glycolysis can continue and produce at least some ATP. 2.

  • Glycolyis and Cellular Respiration

    The goal of glycolysis is to break down glucose to form two pyruvates. All life on earth performs glycolysis. Glycolysis usually occur in the cytoplasm.

  • Glycolysis and Pentose Phosphate pathway

    Glycolysis is the reaction that split a 6 carbon sugar into two three carbon sugars, which is oxidized and form two molecule of pyruvate. (1) It occurs in the cytoplasm, and it consist of ten steps and the ten steps are divided into two phases: The energy

  • Metabolic Pathways

    Draw the glycolysis product with the labeled carbon circled or highlighted. Now take that glycolysis product a little farther. Where is the label after entry into the Citric acid cycle?

  • Link Reaction in Mitochondria

    This solution defines the function of a link reaction in glycolysis and the Kreb cycle. It also identifies the region of the mitochondria it occurs in.

  • Fermentation after glycolis

    When glucose is oxidized to pyruvate (glycolysis), and then all the way to carbon dioxide in the Krebs cycle, an enormous amount of free energy is given off. Most of this free energy is captured by reduced cofactors, NADH and FADH2.

  • Reactions: Inhibit, Catalyse and Glycolosis

    When glycolysis runs faster than the Krebs cycle, citrate (a 6-carbon intermediate in the cycle) builds up and diffuses to the cytosol where it inhibits phosphofructokinase and thus the rate of glycolysis. 2.

  • Flow of carbon atom from triacylglycerols to glucose

    Glycerol enter into glycolysis in the form of DHAP. Sequence of the events for the conversion of glycerol into DHAP are as follows :- 1. ATP + Glycerol = ADP + glycerol 3-P ( enz: glycerol kinase) 2.
