4. oxygenating myoglobin. the myoglobin content of some human muscles is about 8 g kg 1. in sperm whale, the myoglobin content of muscle is about 80 g kg 1 . (a) how much o 2 is bound to myoglobin in human muscle and in sperm whale muscle? assume that the myoglobin is saturated with o 2, and that the molecular weights of human and sperm whale myoglobin are the same. berg, jeremy m.. biochemistry (p. 213). w. h. freeman. kindle edition.

0.01454 grams of oxygen is present per kilogram of human muscle.

0.1454 grams of oxygen is present per kilogram of sperm whale muscle.

Explanation:

Given : The myoglobin is fully saturated with oxygen gas.

Moles of myoglobin = Moles of oxygen gas

Molecular mass of myoglobin = 17,600 g/mol

(assumed same fro whale and human )

Myoglobin content in humans = 8 g/kg

Mole of molyoglobin in human muscles per kg :

Mass of oxygen present in per kg of human muscle:

Moles of oxygen gas × 32g/mol :

g/kg of human muscle

Myoglobin content in whales= 80 g/kg

Mole of molyoglobin in whale muscles per kg :

Moles of myoglobin = Moles of oxygen gas

Mass of oxygen present in per kg of sperm whale muscle:

Moles of oxygen gas × 32g/mol :

g/kg of whale muscle
