Fat breakdown is stimulated by a calorie deficit, increased physical activity, and hormones like adrenaline and glucagon. These factors signal the body to release stored fat for energy production.
Insulin stimulates the uptake of glucose by cells, especially in muscle and fat tissue, which promotes the storage of glucose as glycogen. Insulin also stimulates protein synthesis and inhibits protein breakdown.
The presence of fat in the intestines stimulates cells of the intestinal wall to release hormones such as cholecystokinin (CCK). CCK aids in digestion by promoting the release of bile from the gallbladder and stimulating pancreatic enzyme secretion. This hormonal response enhances the breakdown and absorption of fats and other nutrients in the digestive system.
Cortisol stimulates the breakdown of protein into glucose, raising blood sugar, thereby providing more energy to deal with stress.
Lipase
Insulin stimulates the:Liver to take up glucose, activate glycogen synthesis, shut down glycogenolysis and gluconeogensisMuscles to take up glucose and amino acids (and possibly fatty acids)Adipose tissue to take up glucose and fatty acids (and possibly amino acids)
Growth hormone stimulates lipolysis, which is the breakdown of fats in the body. This hormone helps to release stored fat from fat cells into the bloodstream, where it can be used for energy.
glucagon
The fat kind.
Insulin stimulates the uptake of glucose by cells, especially in muscle and fat tissue, which promotes the storage of glucose as glycogen. Insulin also stimulates protein synthesis and inhibits protein breakdown.
The presence of fat in the intestines stimulates cells of the intestinal wall to release hormones such as cholecystokinin (CCK). CCK aids in digestion by promoting the release of bile from the gallbladder and stimulating pancreatic enzyme secretion. This hormonal response enhances the breakdown and absorption of fats and other nutrients in the digestive system.
Taking in more calories than you're using up stimulates fat formation. If you're burning up what you eat, then you won't get fat.
Yes, adrenaline, cortisol, and growth hormones all stimulate the breakdown of fat.
The gallbladder and pancreas add digestive juices for the breakdown of fat.
Cortisol stimulates the breakdown of protein into glucose, raising blood sugar, thereby providing more energy to deal with stress.
ketosis
It is called emulsification.
Catalyses the breakdown of lipids (fat molecules) into fatty acid and glycerol molecules
