A protein is allowed to spontaneously fold, forming a 3-dimensional shape. How does the energy level of the folded protein compare to that of its unfolded form?

The folded form has a higher energy level.

?The folded and unfolded forms have the same energy levels.

The folded form has a lower energy level.

The unfolded form is slightly more stable and has a lower en?ergy level.
