Document Summary

Giant mound of fat concentrated fat tissue (80 lbs) Allows animal to survive up to 2 week with limited food. The fat is a source of water when metabolized. Absorb as much water as possible before excreted. Condensing water in nostrils to save as much water as possible. Eat intensively before they fly to bulk up fat. Lose half their body weight during migration. Highest flying birds (fly as high as jet aircrafts) Survive cold weather and higher altitudes, very little oxygen. Etc needs oxygen to be terminal electron acceptor oxygen is very important. Animals tap into their fats and are able to maintain locomotion in all environments. When sugar levels drop fatty acids are released by adipocytes (fat cells) Shuttled throughout body to tissues that need it. Mitochondria will oxidize it to form acetyl coa. A lot more atp produced per gram of fat than gram of carbohydrate. The bar headed geese has bigger lungs larger surface area.
