So makes sense. And again just like this one, this is an exergonic reaction. It takes place spontaneously under physiological conditions. Let's look at step three. So the point of step three is to continue destabilizing that molecule. So in step one we destabilized it, increased its energy and made it more reactive because we made it more polar, we added a charge and here we add a second charge and that makes it even more reactive and more likely to actually undergo cleavage in stage two.
