And so eventually, this cooperativity of these different segments and the protein caused the folding process to basically take place quickly, as shown by the following sharp rise in our curve. So the curve describes how most proteins in our body fold or unfold. And notice that the curve shows that the majority of proteins transition sharply from the unfolded to the unfolded state and vice versa. And this is because of the cooperative nature of proteins. So proteins fold and unfold cooperatively. So let's take a look at the following diagram to see exactly what we mean.
