Now, assume that a hypothetical two-subunit hemoglobin has an n of 2. The ratio of the concentrations of the T and R states with no ligands bound, or L, is 1000. The dissociation constant for a ligand binding to a single site in the R state, KR, is 1 torr. The ratio of the dissociation constants KR and KT, or c, is 0.01. Using the concerted model, which oxygen-binding curve best represents the hypothetical two-subunit hemoglobin? 1.0 1.0 0.8 0.8 0.6 0.6 C K 0.4 0.4 0.2 0.2 0 50 100 150 200 50 100 150 200 po₂ (torr) po₂ (torr) 1.0 0.8 KU 0.6 0.4 0.2 0 1.0 50 100 150 200 po₂ (torr) 0.8 0.6 0.4 0.2 50 100 po₂ (torr) 150 200
