WebA Hill coefficient of 1 indicates independent binding, a value greater than 1 indicates positive cooperativity in which binding of one ligand facilitates binding of subsequent ligands at other sites; a value less than 1 indicates negative cooperativity. Webhemoglobin tetramer, forming linear polymers. Blood cells become sickle-shaped (elongated) and cannot travel through capillaries, resulting in tissue death if blood cannot reach. Sickle cell anemia (hemoglobin S) protects against malaria: sickle cells break down and are removed by the spleen more readily when infected with Malaria parasite
