Text of Glycolysis, Gluconeogenesis, Pentose Phosphate Pathwaybiochemistry- .Glycolysis vs. Gluconeogenesis

  • Glycolysis, Gluconeogenesis, Pentose Phosphate

    Pathway

    Highlights from Nelson and Cox’s Lehninger’s Biochemistry

  • Know all of the reactions for Glycolysis Know all structures, names, enzymes, cofactors and Standard Free Energy Change Also, Know if the reaction is reversible under cellular conditions.

  • Glycolysis vs. Gluconeogenesis •  Glycolysis occurs mainly in the muscle and brain •  Gluconeogenesis occurs mainly in the liver

  • The Cory Cycle

  • Pentose Phosphate Pathway

    •  The main goals are to produce NADPH for anabolic reactions and ribose 5-phosphate for nucleotides

  • NADPH Regulates Partitioning into Glycolysis vs. Pentose

    Phosphate Pathway

    •  NADPH inhibits glucose-6-phosphate dehydrogenase
