Gluconeogenesis, Citric acid cycle and oxidative phosphorylation

Gluconeogenesis, Citric acid cycle and oxidative phosphorylation. Glucose Can Be Synthesized from noncarbohydrate Precursors. Gluconeogenesis Is Not a Reversal of Glycolysis. Oxaloacetate Is Shuttled into the Cytosol and Converted into Phosphoenolpyruvate.

Citric acid cycle Krebs cycle, tricarboxylic acid cycle TCA

Citric acid cycle Krebs cycle, tricarboxylic acid cycle TCA The central function is the oxidation of acetyl CoA to CO2 It is the final common pathway for oxidation of fuel molecules Acetyl Co is derived from the metabolism of fuel molecules as amino acids, fatty acids, and carbohydrates.

Citric Acid Cycle 1

Citric Acid Cycle 1. C483 Spring 2013. 1. The net effect of the eight steps of the citric acid cycle is to A) completely oxidize an acetyl group to carbon dioxide. B) convert pyruvate to Acetyl CoA. C) produce a citrate molecule D) produce 8 ATP for every pass through the cycle .
