So in our blood we have a high level of glucose. And what that means is these liver cells will begin to absorb those glucose and the glucose molecules will be transformed ultimately into fructose six phosphate. Now, high levels of glucose means we'll have high levels of fructose six phosphate. And when we have very high levels of fructose six phosphate in a cytoplasm, some of them will begin transforming into a molecule known as fructose 26 bisphosphate. Now, fructose 26 bisphosphate is a very potent, very powerful activator of phosphorptokinase. And what it allows the cells to do is it allows them to convert all these glucose molecules uptake the glucose molecules from the blood, bring that glucose level back to normal and essentially convert those glucose molecules into either ATP molecules or other types of molecules.
