← ScienceWhich outcome occurs when high electron density destabilizes metalloprotein structure?
A)Disulfide bridge formation is inhibited
B)Proton tunneling becomes significantly enhanced
C)Coordination sphere geometry shift occurs✓
D)Solvent reorganization energy is minimized
💡 Explanation
High electron density leads to increased electrostatic repulsion. This triggers ligand reorientation within the **ligand field effect** by distorting the metal ion's coordination shell because it reduces potential energy; therefore metal binding affinity changes, rather than the other processes which involve quantum mechanics or different chemical factors.
