WebBasically, insulin promotes anything that will decrease blood glucose levels. This can happen in two ways: either converting glucose--> pyruvate (glycolysis) or by converting glucose-->glycogen (glucogenesis). Glucagon does the opposite, it promotes any pathway that will increase blood glucose levels. WebThe reaction from glucose to G-6-P, catalyzed by glucokinase in glycogenesis, is essentially irreversible. For this reason, the reverse process is accomplished by another enzyme, G-6 -phosphatase. This enzyme is found in liver and kidney cell membranes and in the endoplasmic reticulum (ER) of intestinal cells, but not in muscle cells.
