In experiment two, he basically took that beaker that contained our denatured enzyme as well as the excess beta mercapto ethanol and our urea. And instead of removing these two agents at the same exact time, he first removed the beta mercapto ethanol. And then after some time, he removed that urea. What he found was the enzyme that was formed was not in its biologically active state. In fact, this enzyme was scrambled. It contained the incorrect pairing of dixulfide bonds.
