So we have our enzyme E, which is basically the hexokinase. And these blue molecules are the glucose molecules. So our hexokinase transforms these glucose molecules shown in blue to these green molecules which are the glucose six phosphate. Eventually, when we build up the concentration of these green molecules, one of these green molecules act as an inhibitor. It binds to an allosteric site on the enzyme that is different than this active side and that deactivates or inhibits the activity of our enzyme. So this is an example of negative feedback inhibition.
