Which type of bond makes it possible for a macromolecule to interact with great specificity with just one out of the many thousands of different molecules present inside a cell?

A. Covalent bonds
B. Noncovalent bonds
C. Hydrogen bonds
D. Ionic bonds

Non covalent interactions.

Explanation: The non covalent interactions can be defined as the interaction among molecules based on the variation among the electromagnetic radiations.

These molecules are not attached to each other based on the sharing of the electrons.

These interactions are Van der Waals, electrostatic, hydrophobic interactions.

The interaction among the molecules is important in order to maintain the three dimensional structure of compound such as carbohydrates and protein molecules.
