← ScienceWhich outcome arises when a cooling solution compromises transmembrane alpha-helix integrity?
A)Protein misfolding and aggregation increases✓
B)Lipid bilayer fluidity significantly rises
C)Covalent bond hydrolysis accelerates greatly
D)Unsaturated phospholipid synthesis rate increases
💡 Explanation
Protein misfolding and aggregation rises because hydrophobic collapse occurs when the integrity of the transmembrane alpha-helix is compromised, losing stability via weakened Van der Waals interactions. Consequent misfolded proteins interact, rather than folding correctly, therefore triggering unwanted intermolecular aggregation and dysfunctional protein interactions.
