Well, if we have low blood glucose levels, what that means is we essentially want to create more glucose molecules. Why? Well, because the cells of our body, such as red blood cells, our brain cells, our skeleton muscle cells, our cardiac muscle cells and so forth, all these different types of cells depend on glucose that is present in the blood. And if the levels of the glucose drops, that can be very dangerous to those cells. Because, for instance, if our red blood cells cannot actually get the glucose from the blood because of the low levels of glucose in the blood, that can essentially lead to many, many different types of problems. And so what happens is the liver cells essentially begin to produce these glucose molecules from non carbohydrate molecules such as pyruvate and lactate and amino acid and glycerol molecules.
