So after a little over a day, we would run out of our glucose supply and our cells would not be able to actually continue functioning. And if we don't ingest the food, we would essentially die. So that's why glucoinogenesis is so crucial, so important, because it gives our body the ability to actually produce these sugar molecules needed by our cells to form ATP from non sugar molecules such as proteins. So, amino acids, fats, the glycerol molecules, as well as the lactate and pyruvate molecules. So now let's take a look at gluco neogenesis. So I said earlier that gluconeogenesis is essentially the process by which we transform the pyruvate molecules into glucose.
