Question

of 28 > Attempt 2 v The molecular weight of sperm whale myoglobin is 17.8 kDa. The myoglobin content of sperm whale muscle is about 80 g kg-!. In contrast, the myoglobin content of some human muscles is about 8 g kg-! Compare the amounts of O, bound to myoglobin in human muscle and in sperm whale muscle. Assume that the myoglobin is saturated with Oy, and that the molecular weights of human and sperm whale myoglobin are the same. How much O, is bound to myoglobin in human muscle? O, bound in human muscle: .114 grams of O, per kilogram of muscle Incorrect How much O, is bound to myoglobin in whale muscle? O, bound in whale muscle: .00112 grams of o, per kilogram of muscle Incorrect The count of oxygen dissolved in tissue water at 37°C is about 3.5 x 10- M. What is the ratio of myoglobin-bound oxygen to dissolved oxygen in the tissue water of sperm whale muscle? ratio of bound oxygen to dissolved oxygen: 12.86 Incar MacBook Air 888 4 E % 5 & 7 4 * 6 00 9 0 { R T Y U I O P I F J T K L
