BIOL 200 Lecture Notes - Lecture 4: Phosphoenolpyruvate Carboxykinase, Glycogen Phosphorylase, Pyruvate Carboxylase
Document Summary
Glycogen, (1-4) and (1-6) linkages, reducing and non-reducing ends, phosphoglucomutase, uridine diphosphate glucose (udp- glucose), udp-glucose pyrophosphorylase, glycogen synthase, branching enzyme, glycogenin, glycogen phosphorylase, phosphorolysis, (1,6) glycosidase, debranching and transferase enzymes. Glycogen breakdown (ignore the mechanism of glycogen phosphorylase). Allosteric regulation of glycogen phosphorylase (ignore the section entitled phosphorylase kinase is activated by phosphorylation and calcium ions ). Gluconeogenesis, pyruvate carboxylase, carboxylation, biotin, phosphoenolpyruvate carboxykinase, fructose 1,6-bisphosphatase, glucose-6-phosphatase, futile and substrate cycles, cori cycle. The steps that bypass the irreversible steps of glycolysis. These are the reactions catalyzed by pyruvate carboxylase, phosphoenolpyruvate carboxykinase, fructose 1,6-bisphosphatase, and glucose 6-phosphatase. Regulation of gluconeogenesis (ignore the section entitled the balance between glycolysis and gluconeogenesis in the liver is sensitive to blood glucose concentration ) Substrate cycles, the cori cycle (start at the section entitled substrate cycles amplify metabolic signals and produce heat ).
