We have negative feedback inhibition and positive feedback which is basically our activating process. So let's begin with the negative feedback inhibition. So if the effector molecule binds to the allosteric site of the enzyme and inhibits its activity, this effector molecule is known as the inhibitor. And one example of this negative feedback inhibition process is in glycolysis. So in our cells, in our body, our glucose basically is broken down into pyruvate molecules. And this concept, this process is known as glycolysis.
