So the addition of a charged moiety onto the glucose destabilize the structure of that glucose and increases its energy. And this makes it more reactive and more likely to actually undergo and continue glycolysis. Now let's focus in on the hexokinase. So what is a hexokinase? Well, a hexokinase is a protein kinase that basically catalyzes the addition of asphalt groups onto hexosugars. And glucose is an example of a HEXO sugar.
