In a protein that undergoes frequent conformational changes, which type of beta sheet might be more advantageous and why?

• A. Antiparallel beta sheets might be more advantageous due to their flexibility from weaker hydrogen bonds.
• B. Parallel beta sheets might be more advantageous due to their flexibility from weaker hydrogen bonds.
• C. Both types are equally advantageous in such proteins.
• D. Neither type is advantageous in proteins with frequent conformational changes.

Answer: (B)
