Determine the p50 for variant A to the nearest 5 torr (i.e., if the p50 was 12, you would write 10). Determine the fraction of the hemoglobin B bound with O2 in the lungs (pO2 = 100 torr) that delivers oxygen to the tissues (pO2 = 20 torr)? Answer to the nearest 0.05 value (for example, 0.10 %3D or 0.15). Which hemoglobin variant (write A or B or same) delivers more oxygen to tissues?
