Since аncient times it hаs been оbserved thаt certain game birds, such as grоuse, quail, and pheasants, are easily fatigued. The Greek histоrian Xenophon wrote, The bustards ... can be caught if one is quick in starting them up, for they will fly only a short distance, like partridges, and soon tire; and their flesh is delicious". The flight muscles of game birds rely almost entirely on the use of glucose-1-phosphate for energy, in the form of ATP. The glucose-1-phosphate is formed by the breakdown of stored muscle glycogen, catalyzed by the enzyme glycogen phosphorylase. The rate of ATP production is limited by the rate at which glycogen can be broken down. During a "panic flight," the game bird's rate of glycogen breakdown is quite high, approximately 120 mmol/min of glucose-1-phosphate produced per gram of fresh tissue. Given that the flight muscles usually contain about 0.35% glycogen by weight, calculate how long a game bird can fly. (Assume the average molecular weight of a glucose residue in glycogen is 162 g/mol.)
