The insulin molecules invaded like a miniature marauding army. Rapidly infiltrating the veins, they rushed headlong into the heart, to be pumped out through the arteries. Within seconds the invasion spread throughout the body, latching on to receptors on the cell membranes and causing the cellular gates for glucose to open. Instantly glucose poured into all the cells of the body, resulting in a precipitous fall of the glucose level in the bloodstream. The first cells to be adversely affected by this were the nerve cells, which cannot store glucose and need a highly regulated, constant supply of the sugar to function. As minutes passed and the insulin onslaught continued, the neurons, particularly those of the brain, rapidly became starved of their lifeblood glucose and their function began to falter.
