And the reason we want to regulate this is to basically make sure that our intermediate B, the glucose six phosphate, doesn't build up in concentration. So this is a method by which we basically make sure that we don't have too much of our intermediate in this reaction. So this is another diagram of this particular negative feedback inhibition mechanism. 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.
