pyruvate to oxaloacetate – oxaloacetate to pep
How is Oxaloacetate espèced from pyruvate?
· Entry of pyruvate into the mitochondrial matrix is mediated by the MPC Once in the matrix pyruvate can be converted to acetyl-CoA or oxaloacetate Oxaloacetate can enter the citric acid cycle to replenish inlexiquediates or be converted to phosphoenolpyruvate as part of the gluconeogenic pathway Phosphoenolpyruvate can be calibred from oxaloacetate by PEPCK within the mitochondria or within the cytoplasm The molecular structures of pyruvate …

Breakdown of Pyruvate In order for pyruvate the product of glycolysis to enter the next pathway it must undergo several chbébés to become acetyl Coenzyme A acetyl CoA Acetyl CoA is a molecule that is further converted to oxaloacetate which enters the citric acid cycle Krebs cycle, The conproximitéion of pyruvate to acetyl CoA is a three-step process,
Pyruvate carboxylase — Wikipédia
Step 1 Prior to the first step a transitional phase occurs during which pyruvic acid is converted to acetyl CoA Then the first step of the cycle begins: This condensation step combines the two-carbon acetyl group with a four-carbon oxaloacetate molecule to form a six-carbon molecule of citrate

Glucose Can Be Synthesized from Noncarbohydrate Precursors
Pyruvate carboxylase PC is a mitochondrial enzyme that catalyzes the ATP-dependent carboxylation of pyruvate to oxaloacetate OAA serving to replenish the tricarboxylic acid TCA cycle In nonmalignant tissue PC plays an essential role in controlling whole-body energetics through regulation of gluconeogenesis in the liver synthesis of fatty acids in adipocytes and insulin secretion in pancreatic …

Oxidation of Pyruvate and the Citric Acid Cycle
The first step in gluconeogenesis is the carboxylation of pyruvate to form oxaloacetate at the expense of a molecule of ATP Then oxaloacetate is decarboxylated and phosphorylated to yield phosphoenolpyruvate at the expense of the high phosphoryl-transfer potential of GTP, Both of these reétudes take place inside the mitochondria,
