← ScienceCarbon monoxide poisoning impairs cellular respiration because disrupting which mechanism?
A)Hemoglobin's oxygen-binding orbital interactions✓
B)Red blood cell osmotic equilibrium
C)Pulmonary surfactant surface tension
D)Mitochondrial ATP synthase proton gradient
💡 Explanation
CO poisoning inhibits oxygen transport via hemoglobin because competitive ligand binding alters electronic orbital configurations inhibiting O2 binding, therefore decreasing cellular respiration rather than CO2 transport issues at the cell.
