Glycolysis

CONTENTS What is glycolysis? Glycolysis: the first metabolic pathway to be elucidated Why is glycolysis so important? The steps of glycolysis Reaction 1: glucose phosphorylation to glucose 6-phosphate The importance of glucose phosphorylation Other possible fates of glucose 6-phosphate Reaction 2: isomerization of glucose 6-phosphate to fructose 6-phosphate Reaction 3: phosphorylation of fructose 6-phosphate to […]

Gluconeogenesis

CONTENTS What is gluconeogenesis? Why is gluconeogenesis important? Where does gluconeogenesis occur? Irreversible steps of gluconeogenesis From pyruvate to phosphoenolpyruvate Phosphoenolpyruvate precursor: pyruvate or alanine Phosphoenolpyruvate precursor: lactate From fructose 1,6-bisphosphate to fructose 6-phosphate From glucose 6-phosphate to glucose Gluconeogenesis: energetically expensive Coordinated regulation of gluconeogenesis and glycolysis Regulation of gluconeogenesis Pyruvate carboxylase Fructose 1,6-bisphosphatase […]
