7. Hydrogen bonds are a crucial component of biomolecular structure and biomolecular interactions. In the following drawings, draw in several hydrogen bonds that are possible between atoms within the same molecule or between different molecules: A: Protein structure H₂C₁ #1 N-H N-C 0=C HR 1 N-H ORU 0=C N-HH-CR B: DNA base-pairing H H-N N-H N=C C-C H 0=C NIH C C=N HR 0=3₁ HR H-9-4 0-0 NIH N-H 0=C 0=0 RECH N-H N-H 0=8-₁ OH HR C: Plant cell wall (cellulose) CH₂OH H BỆNH O=C HA CH OH H CH₂OH ( он H HC-0 CH₂₂OH H OH 1 TH OH H IN HC- OH H CH₂OH CH₂₂OH O OH H C-CH H bH CH₂₂OH VA HS COK H ОН Biomolecules like DNA, proteins, and carbohydrates depend on hydrogen bonds to maintain their overall structure. However, each individual hydrogen bond is relatively weak. Using protein structure from the question above as an example, explain how to resolve the apparent contradiction between these two statements.
