Document Summary
Which is more the economical fuel? (more bang for the buck ): cho or. Faty acids stored in plants and animals as triglycerides. Fat is energy genes; 1g fat = 9 kcals. 1- subcutaneous: under the skin main storage area. 2- visceral fat: mainly in abdomen around organs. Insulin resistance is the opposite of insulin sensiivity. Large volume liposucion removed 20lbs far from abdominal secion. Hormones (ex: adrenaline, epinephrine) to simulate more fuel. Enters area where body needs it: uptake: Higher fa in blood more taken up by muscle: fa into mitochondria, fa to acetyl coa: 1 fa sliced , 16 carbons acetyl coa: oxidaion of acetyl coa for energy: Products of co2, h2o, and 129 atp! Oxidaion of fat releases a lot of atp, but 5 steps to get there! Mobilizaion, uptake, mitochondria, slice, oxidaion to get energy. Triglycerides faty acid (16c) + 46 o2 acetyl coa co2 + h2o + 129 atp.
