← ScienceWhich outcome arises when hydrogen bonds break in a protein molecule due to increasing temperature?
A)Peptide bond hydrolysis accelerates significantly
B)The protein's tertiary structure is disrupted✓
C)Disulfide bonds become irreversibly cross-linked
D)Alpha helix formation becomes energetically favorable
💡 Explanation
As temperature rises, increased kinetic energy disrupts hydrogen bonds, leading to protein denaturation because the weak interactions maintaining the tertiary structure are overcome. Therefore, tertiary structure disruption occurs rather than peptide hydrolysis, disulfide cross-linking, or alpha-helix formation, requiring different bond-specific mechanisms.
