  2. Pyruvic acid - Wikipedia

    en.wikipedia.org/wiki/Pyruvic_acid

    Pyruvic acid (CH 3 COCOOH) is the simplest of the alpha-keto acids, with a carboxylic acid and a ketone functional group. Pyruvate , the conjugate base , CH 3 COCOO − , is an intermediate in several metabolic pathways throughout the cell.

  3. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Without oxygen, pyruvate (pyruvic acid) is not metabolized by cellular respiration but undergoes a process of fermentation. The pyruvate is not transported into the mitochondrion but remains in the cytoplasm, where it is converted to waste products that may be removed from the cell. This serves the purpose of oxidizing the electron carriers so ...

  4. Pyruvate dehydrogenase complex - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_dehydrogenase_complex

    Acetyl-CoA may then be used in the citric acid cycle to carry out cellular respiration, and this complex links the glycolysis metabolic pathway to the citric acid cycle. Pyruvate decarboxylation is also known as the "pyruvate dehydrogenase reaction" because it also involves the oxidation of pyruvate. [2]

    d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...

  6. Pyruvate dehydrogenase - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_dehydrogenase

    The conversion is crucial because acetyl-CoA may then be used in the citric acid cycle to carry out cellular respiration. [2] To distinguish between this enzyme and the PDC, it is systematically called pyruvate dehydrogenase (acetyl-transferring).

  7. Lactic acid fermentation - Wikipedia

    en.wikipedia.org/wiki/Lactic_acid_fermentation

    Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution.

    A FedEx contract worker has been busted for allegedly dumping dozens of packages in the woods to avoid working late. Latavion Lewis was arrested after a post office in Bonifay, Florida, received ...

  9. Pyruvate kinase - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_kinase

    Many Enterobacteriaceae, including E. coli, have two isoforms of pyruvate kinase, PykA and PykF, which are 37% identical in E. coli (Uniprot: PykA, PykF).They catalyze the same reaction as in eukaryotes, namely the generation of ATP from ADP and PEP, the last step in glycolysis, a step that is irreversible under physiological conditions.
