And that second segment, by breaking down, causes a third segment in close proximity to also break down. And so these different segments of the protein structure, as they begin to break down, they cooperate with one another to basically unfold that entire protein structure. And so eventually, because of this cooperative nature, we have this really sharp rise in the amount of protein that are denatured. Likewise, we can also look at it in the other way. Let's suppose we're going from this to this state. So we decrease the temperature of our solution.
