The bond energies associated with noncovalent attractions in the cell are too weak to resist disruption by thermal motion. However, cellular macromolecules can interact specifically AND strongly with each other (or fold by themselves) merely via such interactions. How is this possible?

A) The bond energies increase radically when two interacting molecules approach each other.
B) The interacting molecules also fortify their binding via covalent bonds to keep them from dissociation.
C) Many weak bonds together in a complementary geometry can afford a strong binding.
D) The cell lowers its internal temperature to reduce thermal motion of molecules and enhance the weak attractions.
