Each year, Canada geese lift off in precise formation from their northern breeding grounds. They head south to spend the winter months in warmer climates, then make the return trip in spring. As is the case for other migratory birds, their flight muscle cells are efficient at using fatty acids as an energy source. Remember, the carbon backbone of fatty acids can be cleaved into small fragments that can be converted to acetyl-CoA for entry into the Krebs cycle.
Suppose a lesser Canada goose from Alaskas Point Barrow has been steadily flapping along for about three thousand kilometers and is approaching Klamath Falls, Oregon. It looks down and notices a rabbit sprinting from a coyote with a taste for rabbit.
With a stunning burst of speed, the rabbit reaches the safety of its burrow.
Which energy-releasing pathway predominated in muscle cells in the rabbits legs Why was the Canada goose relying on a different pathway for most of its journey And why wouldnt the pathway of choice in goose flight muscle cells be much good for a rabbit making a mad dash from its enemy
