WebNov 2, 2024 · Gluconeogenesis and glycogenolysis are the two pathways essential for glucose homeostasis. Figure 5.1 illustrates the time frame and overlap of glycogenolysis and gluconeogenesis. These pathways are activated nearly simultaneously when the insulin to glucagon ratio becomes sufficiently reduced. Over time, the reliance on the pathways … WebThe rate-limting enzyme is glycogen phosphorylase. While a hydrolase uses water to break bonds, a phosphorylase uses an inorganic phosphate. Glycogen phosphorylase is activated by glucagon in the liver, but AMP and epinephrine in the liver. It is inhibited by ATP. Glycogen phosphorylase can only break α-1,4 bonds.
