Brainscape Find Flashcards Why It Works Educators ... pyruvate oxidation, Krebs cycle, Gluconeogenesis, glycogenesis, regulation, Blood glucose level, diabetes, fructose/galactose (PPP not incl.) And it does turn out that ATP is actually an allosteric regulator of a couple enzymes in glycolysis. Graduate. The breakdown in gluconeogenesis will eventually force substrate back into pyruvate which can reversible retrovert back to lactate and alanine: Term. Gluconeogenesis definition. It is also called “Endogenous glucose Production” (EGP). PDF. The first step to be bypassed is pyruvate to phosphoenolpyruvate, in this step pyruvate does not simply change into PEP, but it is through the bypassed step. Gluconeogenesis o Go to the next quiz: Tricarboxylic Acid Cycle. 10/04/2011. biochemistry ii chapter 16: glycogen metabolism and gluconeogenesis textbook: fundamentals of biochemistry: life at the molecular level, 5th edition.
