Now, we still really haven't answered a very important but very simple question. Why do our cells, why does our body actually need glucose? Mugenesis why can't we depend solely on the food for our sugar source? Well, that's because we can actually store a limited amount of sugar inside our body. So to be more specific, in our fluid, so places like our blood plasma and the fluid found in the cell, so cytoplasm and fluid found in our tissue, in these areas, we can store a maximum of about 20 grams of glucose. Now, in our glycogen stores, we can basically store about 190 grams of usable sugar, sugar that can be readily used and can be readily accessible by those cells.
