Each of us is made up of more than 30 trillion cells. When we spike, they all feel it. Glucose’s primary biological purpose once it enters a cell is to be turned into energy. The powerhouses responsible for this are microscopic organelles found in most of our cells called mitochondria. Using glucose (and oxygen from the air we breathe), they create the chemical version of electricity to give each cell the power to do whatever it needs to. As glucose floods into our cells, it heads straight to the mitochondria to undergo its transformation.
