Catabolism is the breakdown of molecules into smaller units. The molecule that is common to the catabolism of fat and glucose is known as acetyl CoA.

When does fat catabolism usually occur?
When there is no glucose available. ie: starvation
What is the catabolism of fat called?
I believe it is Lipolysis.
What hormone deals with fat catabolism by the cells?
The growth hormone deals with fat catabolism by the cells. The growth hormone is secreted by the anterior pituitary in the endocrine system.
What Is the abnormal production of ketone bodies in the blood and tissue as a result of fat catabolism in cells?
Ketoacidosis
What fat molecule has the most H atoms?
The fat molecule that has the most H, or hydrogen, atoms is the saturated fat molecule. This is because this particular molecule has no double bonds in its structure.
The catabolism of glucose fat and protein and the anabolism of fats and cholesterol all depend upon what molecule?
ATP adenosine-tri-phosphate
When does fat catabolism usually occur?
When there is no glucose available. ie: starvation
What part of a fat molecule CAN be used to make glucose?
The part of a fat molecule that can be used to make glucose is the fatty acids. The daily lipid intake can be produced from fatty acids.
What does fat catabolism produces?
unfat
What short term energy source is provided after cellular glucose supplies are depleted?
Glycogen is a short-term energy source after cellular glucose supplies are depleted. It is stored in the liver and the muscle tissue.
What is the catabolism of fat called?
I believe it is Lipolysis.
What produces ketone bodies?
fat catabolism
Why do levels of GHRH and CRH rise during the resistance phase of the general adaptation syndrome?
During the resistance phase of the general adaptation syndrome, there is a high demand for glucose, especially by the nervous system. The hormones GH-RH and CRH increase the levels of GH and ACTH, respectively. Growth hormone mobilizes fat reserves and promotes the catabolism of protein; ACTH increases cortisol, which stimulates both the conversion of glycogen to glucose and the catabolism of fat and protein.
What lipid is the body's long term energy storage molecule?
Triglycerides are a common lipid for energy storage. Triglycerides help in the process of moving blood glucose and adipose fat from the liver.
What does 'fat burns in a carbohydrate flame' mean?
This means that you need a sufficient supply of glucose (carbs) in your body as glucose to sustain exercise and once you are depleted of carbohydrates (blood glucose, stored glycogen), any intensity of exercise will become difficult. Even though typical 'fat burning exercise' is lower intensity (fats are metabolised greatly at lower (up to moderate) intensities of exercise), you still need blood glucose to keep exercise pace without fatigue. So in other words, without glucose, you have restriced chances of utilising fats because glycogen and glucose depletion are what cause enhanced local and whole-body symptoms of fatigue during exercise. A: Burning Fat in a "carbohydrate flame" is more than just maintaining the BLG and Glycogen stores to maintain exhersion over longer periods of time. This statement acknowledges that fact that there are common pathways that both fat and carbohydrate substrates are oxidised and that fat metabolism is dependent on a background level of carbohydrate catabolism. If you consider the Citric acid cycle, many of the intermediates are products of glucose catabolism; eg oxaloacetate. Both carbohydrates and fats must be broken down to acetyle CoA before they enter this stage of aerobic metabolism. If you deplent your body of adequate carbohydrates many of the intermediates of the Citric acid cycle will be "borrowed" in synthesise glucose (gluconeogenesis) to maintain BGL's. It is intuative then to assume that if you remove the intermediates that are required for oxidation of fat there will be a reduced capacity to burn fat. Moral of the story: low carbohydrate diets will ultimately fail in maintaining lasting weight loss because your ability to burn fats is blunted because fat oxidation is dependent on background carbohydrate catabolism.
