A patient carrying a mutant form of hemoglobin (KD = 48 torr) is planning to take part in a hiking trip that involves strenuous physical activity at ~10,000 feet above sea level. The mutant hemoglobin has reduced oxygen binding cooperativity (n = 2.2) and displays no major structural abnormalities. a. Calculate the percent saturation of hemoglobin in the lungs (pO2 = 70 torr at this elevation) for this patient and for an individual carrying a normal version of hemoglobin b. Calculate the percent saturation of hemoglobin in active skeletal muscle tissue (pO2 = 15 torr) for this patient and for an individual carrying a normal version of hemoglobin c. Will this patient transport oxygen from the lungs to active muscle tissues more or less efficientlythan an individual with a normal version of hemoglobin on this trip? Briefly explain your answer
The arterial O₂ concentration is given by the following expression [0₂] = 0.003 P0₂ + (PO₂)².8 +(26) 2.8 1. ЗЧНЬ (Рог ) 2-8 Where Poz is the alveolar O₂ pressure and Hb is the hemoglobin concentration in g/dL, respectively A subject who is at 0-95 ATM (211-0₂) has an arterial O₂ concentration of 19ml/dL and and arterial CO₂ pressure of 38mm Hg. Also, VO₂ = 340mL/min.; VCD₂ = 289 mL/min. Therefore, your hemoglobine level is: A. 14.39 Idl 8. 14.8 g/dl C. 15.2 g/dl D. 15.7g/dL E. 16 g/dL

Following several days at high altitude the body responds to the decreased oxygen content of the atmosphere by increasing the amount of 2,3-bisphosphoglycerate it produces. Based on this information and refering to the graph below, identify the correct response from the options.

Answer to the nearest 0.05 value (for example, 0.10 or 0.15). Which hemoglobin variant (write A or B or same) delivers more oxygen to tissues? Fraction bound with O2
Inorganic compounds of metallic mercury are presumed from metabolic studies to distribute uniformly after inhalation or ingestion with 8% going to the liver and 92% to the total body. Biological clearance of mercury in each of these tissues occurs by two compartments, 95% with a biological half-life of 40 days and the remaining 5% with a biological half-life of 10,000 days. For an intake of 1 MBq of 203Hg (Tr= 46.61 d). Determine the following 1. Total number of transformations in the Liver. 2. Total number of transformations in the total body.
