Question

Which characteristics of weak noncovalent interactions enable the assembly, stability, and functions of biomolecules? (Pick one or more)

A) They are readily reversible, whereas covalent bonds require a much larger input of energy to break.
B) They have a large cumulative effect, although individual interactions are relatively weak.
C) They are stable, requiring a large amount of energy to break.
D) They are not affected by the surrounding aqueous environment.

Answer 1

Weak noncovalent interactions like hydrogen bonds and van der Waals interactions facilitate the reversible assembly, stability, and function of biomolecules through their reversibility, cumulative effect, and responsiveness to their aqueous environment.

Step-by-step explanation:

The characteristics of weak noncovalent interactions that enable the assembly, stability, and functions of biomolecules include, but are not limited to:

• Reversibility: They are readily reversible, allowing biomolecular structures like proteins and DNA to assemble and disassemble as needed.
• Cumulative effect: While individual noncovalent interactions are weak, their large number produces a strong cumulative effect that contributes to the stability and proper function of biomolecular structures.
• Environmental responsiveness: Unlike covalent bonds, these interactions are affected by their surrounding aqueous environment, which plays a role in their formation and stability.

It should be noted that these noncovalent interactions, including hydrogen bonds and van der Waals interactions, are not as stable as covalent bonds and do not require a large amount of energy to break, making them distinctively significant for dynamic biological processes.
