During constant flight, hummingbirds expend about 2.9 kJ/hr, relying on fat
oxidation as an energy source.
(a) Calculate the gms of fat necessary to sustain a 20-hr nonstop flight.
(b) If the birds relied on carbohydrate for this energy, how much additional
weight would they have to start the flight with?
After strenuous exercise, you may notice that your muscles burn and feel sore the next day. Which statement best explains this phenomenon? (a) Proteins in muscle cells are being digested to provide energy. (b) Carbon dioxide is building up in muscle cells and changing their pH. (c) Spontaneous combustion occurs during strenuous exercise, so avoid it at all costs! (d) ATP is accumulating in muscle cells, causing a burning sensation. (e) Without adequate oxygen, muscle cells are fermenting pyruvate into lactic acid.

- Which of the following statements is not true? (a) Glycolysis is the first stage of cellular respiration. (b) Glycolysis can proceed under low oxygen levels with the assistance of fermentation. (c) Glycolysis produces less ATP than does either the Krebs cycle or oxidative phosphorylation. (d) Glycolysis produces most of the ATP required by aerobic organisms like us.arrow_forwardSince ancient times it has been observed that certain game birds, such as grouse, quail, and pheasants, are easily fatigued. The Greek historian 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 ofglycogen 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.
