Now why does that actually make sense? Well, if we have high levels of glucose in our blood, our kidney cells and liver cells want to actually remove the excess glucose from our blood because high levels of glucose can actually be very toxic. And so what that means is these liver cells want to pull in these glucose molecules and then break down the glucose molecules to ATP molecules because that will ultimately help us decrease the level of glucose in our blood. Now what about the other case? What about if we have low blood glucose level, for example? Let's say we're fasting.
