Answer:
The amount of O2 bound to myoglobin in whale sperm muscle is greater than that in human muscle.
O2 bound in human muscle is 0.0144 gram of O2 per kilogram of muscle.
O2 bound in whale muscle is 0.144 gram of O2 per kilogram of muscle.
Ratio of bound oxygen to dissolved oxygen is 4114.29
Explanation:
Molecular weight of sperm whale myoglobin = Molecular weight of human myoglobin = 17.8 kDa = 17.8×1000 = 17,800 Da
1 Dalton (Da) = 1 g/mol
Therefore, MW = 17,800 g/mol
Myoglobin content of human muscle = 8 g/kg
Amount of O2 bound to myoglobin in human muscle = mass ÷ MW = 8 g/kg ÷ 17,800 g/mol = 0.00045 mol/kg
Myoglobin content of whale sperm muscle = 80 g/kg
Amount of O2 bound to myoglobin in whale sperm muscle = mass ÷ MW = 80 g/kg ÷ 17,800 g/mol = 0.0045 mol/kg
The amount of O2 bound to myoglobin in whale sperm muscle (0.0045 mol/kg) is greater than that in human muscle (0.00045 mol/kg) by a factor of 10 (0.0045/0.00045 = 10)
O2 bound in human muscle = 0.00045 mol/kg × 32 grams/1 mol = 0.0144 gram of O2 per kg of muscle
O2 bound in whale muscle = 0.0045 mol/kg × 32 grams/1 mol = 0.144 gram of O2 per kg of muscle
Ratio of bound oxygen to dissolved oxygen of sperm whale muscle = 0.144 ÷ 3.5×10^-5 = 4114.29
