Difference Between Absorptive and Postabsorptive State

The key difference between absorptive and postabsorptive state is that absorptive state is the state that digests foods and absorbs nutrients into our bloodstream while the postabsorptive state is the state in which the nutrient absorption does not occur, and the body relies on the energy reserves for energy.

What happens during the Postabsorptive state?

The postabsorptive state, or the fasting state, occurs when the food has been digested, absorbed, and stored. You commonly fast overnight, but skipping meals during the day puts your body in the postabsorptive state as well. During this state, the body must rely initially on stored glycogen.

What is a metabolic state?

Metabolic States: A Balance Between Energy and Biosynthesis

The metabolic demands of a cell are a balance between its energetic demands and its biosynthetic requirements to support cellular function. Cell types requiring high-energy production adopt a metabolic state that directs most nutrient flux into ATP production.

What is the primary hormone of the Postabsorptive state?

Hormones: Postabsorptive state is largely caused by lack of insulin; also utilizes glucagon, but stress hormones (cortisol and epinephrine) can fill in for glucagon. Glucagon mainly affects liver.

What happens in the fed state?

The absorptive state, or the fed state, occurs after a meal when your body is digesting the food and absorbing the nutrients (anabolism exceeds catabolism). Digestion begins the moment you put food into your mouth, as the food is broken down into its constituent parts to be absorbed through the intestine.

What is important in the absorptive state?

A number of nutrients in the blood can stimulate its release. However, glucose is the most important one. Insulin's major role is to switch the body from a fasting to an absorptive state of metabolism. Insulin stimulates the synthesis and storage of glycogen in myocytes.

Which hormones dominate the absorptive state?

As blood glucose and amino acid concentrations rise following the meal, insulin is released from beta cells of the pancreatic islets. Insulin is the major hormone, directing organs, tissues and cells in terms of what to do with the absorbed nutrients during the absorptive state.

What are the 3 metabolic types?

The three main body types (or somatotypes) are endomorph, ectomorph and mesomorph. You'll probably identify most with one of these, or you may see yourself reflected in a combination of two.

What is an example of a metabolic process?

The processes of making and breaking down glucose molecules are both examples of metabolic pathways. A metabolic pathway is a series of connected chemical reactions that feed one another. ... In contrast, cellular respiration breaks sugar down into smaller molecules and is a "breaking down," or catabolic, pathway.

What is an example of a metabolic disease?

Some affect the breakdown of amino acids, carbohydrates, or lipids. Another group, mitochondrial diseases, affects the parts of the cells that produce the energy. You can develop a metabolic disorder when some organs, such as your liver or pancreas, become diseased or do not function normally. Diabetes is an example.

Which hormone drives the most pathways in the absorptive state?

Which hormone drives the most pathways in the absorptive state? Insulin has wide-ranging effects on all nutrients during the absorptive state.

What does Glycogenesis mean?

Glycogenesis, the formation of glycogen, the primary carbohydrate stored in the liver and muscle cells of animals, from glucose. Glycogenesis takes place when blood glucose levels are sufficiently high to allow excess glucose to be stored in liver and muscle cells.

What happens to glucose in the absorptive state?

During the absorptive state, anabolic processes use glucose in a variety of ways. In the liver, glucose is converted to glycogen or fat, which store energy for future use. Fat is also stored in adipose tissue and glycogen in muscle tissue.
