Which mechanism maintains protein structure despite thermal energy?

A)Hydrophobic interactions driving folding
B)Increased kinetic destabilizes sidechains.
C)Decreased vibrational energy disrupts bonds
D)Covalent bonding becomes highly strained

💡 Explanation

Hydrophobic interactions aggregate nonpolar amino acids in the protein's interior, therefore stabilizing the folded structure against thermal unfolding because the hydrophobic effect dominates at physiological temperatures, rather than covalent or weakening bonds.
