Regulation of cellular glucose uptake The binding of insulin to the insulin receptor stimulates a cascade of protein phosphorylations leading to the translocation of glucose transporters (GLUT4) to the cell membrane and an increased cellular uptake of glucose (3, 42)

The reason for this discrepancy is almost always bioavailability

Hydrogen peroxide is made as a by-product, and peroxisomes are considered the main site of its intracellular production
