Once a meal has been completely absorbed (typically three to five hours after a meal), the metabolism changes to a fasting state, which is synonymous with ” post-absorptive state,” in contrast to the “post-prandial” state of ongoing digestion. Following a glucose load, the body assumes an absorptive state, and its metabolic profile is primarily regulated by insulin. During the postabsorptive state, both glucose production and glucose conservation help maintain blood glucose level: Hepatocytes produce glucose molecules and export them into the blood, and other body cells switch from glucose to alternative fuels for ATP production to conserve scarce glucose. The main components through which the nutrients can pass include the blood and lymph. Metabolites are transformed to fat if they are not used for anabolism. All rights reserved. absorptive state. Absorptive state is the period in which the gastrointestinal tract is full and the anabolic processes exceed catabolism. Services, Digestive System II: The Lower Gastrointestinal Tract, Working Scholars® Bringing Tuition-Free College to the Community. Various methods can induce trance-like states including hypnosis, chanting, dancing, taking psychoactive substances, and drumming (Becker 2004; Vaitl et al. Absorption in the Intestine The presence of villi in the intestine helps in the process of absorption after the digestion of the food is completed. Amino acids and fats are used to form degraded protein, and small amounts are used to provide ATP.

C) adipocytes release fatty acids to the circulation. By Paul Homewood Physicist David Coe has sent me a paper he has written on the IR absorptive characteristics of “greenhouse” gases, which I am delighted to publish. The processes that occur during the post-absorptive state (after food has been digested) are: Our experts can answer your tough homework and study questions. B.

A) Most of the glycogen stores of the body are found here. The Absorptive 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).

The absorptive state lasts for four hours, during and after each meal. 12. Absorptive state and postabsorptive state are two main states of energy metabolism. During this interval, transient increases in plasma glucose, amino acids, and triacylglycerols (TAG) occur, the latter primarily as components of chylomicrons synthesized by the intestinal mucosal cells (see p. 228). Insulin promotes the synthesis: Definition. There are metabolic pathways which form a two-part process; the first part is the one mentioned called, 'Catabolism,' during which the body processes food to use for energy. Nutrient processing in the absorptive state Carbohydrates - Simple sugars are sent to the liver where they are converted to glucose. The absorptive state is regulated mainly by insulin, whereas the postabsorptive state is regulated by multiple hormones. Amino Acids - The liver deaminates amino acids to keto acids to be used in the krebs cycle in order to produce ATP. Glycogen is the principal storage form of glucose in animal cells. as body progresses from absorptive to post absorptive state all other organs, besides __, switch to fatty acids as major energy source: brain: during transition phase, from absorptive to post absorptive state, __ begins in adipose tissues & released __ __ are picked up by tissue cells & … Beta oxidation _____ happens in the cytoplasm, whereas _____ happens in the mitochondrion. This allows them to freely pass through capillary walls. The fuel used for this process is glucose. D. occurs in the large intestine. 52. 13.

What is the primary goal during absorptive state? During the absorptive state, assuming a balanced diet without need for gluconeogenesis, give examples of how the body will use the absorbed carbohydrates, absorbed lipids and absorbed amino acids. A. Glucagon levels increase B. The absorptive state lasts for four hours, during and after each meal. 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).

Gluconeogenesis occurs especially in the absorptive state during and shortly after a meal. In the liver, glucose is converted to glycogen or fat, which store energy for future use. Which of the following statements about the liver is true? In the absorptive state, a fraction of the absorbed amino acids is taken up by the liver (Fig. The main components through which the nutrients can pass include the blood and lymph. In a low carb environment, other body cells will also begin to use triglycerides as energy sources. Learn vocabulary, terms, and more with flashcards, games, and other study tools. During the absorptive state, our body digests foods and absorbs nutrients into the blood. Distinct mechanisms are in place to facilitate energy storage, and to make stored energy available during times of fasting and starvation. The absorptive state in trance relates to the hyper-focused immersive experience of flow (Csikszentmihalyi 1990) and has been cultivated in many musical and contemplative traditions (Harner 1990; Becker 2004; Walsh 2007).

The glucose then travels to the blood or is converted to glycogen and fat (triglyceride). Which of the following occurs during the absorptive state? Amino acids and fats are used to form degraded protein, and small amounts are used to provide ATP. During this state glucose is the most important energy fuel. 101.The absorptive state A. occurs immediately to about 4 hours after meals. B) insulin levels are low. During the absorptive state, the stomach and intestines contain nutrients that are being absorbed by the body. Throughout this state, digested food is converted into sugar or glucose. answer! Which of the following occurs during the postabsorptive state? lactic acid. Which of the following occurs during the absorptive state? 9.1) and converted to ketoacids that are oxidized via the citric acid cycle and other pathways. The digestion occurs with the help of enzyme activity and then the nutrients directly enter the body fluids. (Note: more than one answer may be correct). Insulin is a hormone that allows glucose to enter the cells and be used for energy. The rest is used for energy in adipose cells, skeletal muscles, and hepatocytes. 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. The post-absorptive stages of metabolism occur from the lipid absorption in the intestines. 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. C. has gluconeogenesis as one of its main events. When a person is active, most of the body heat is generated in the brain, heart, and endocrine glands. fatty acids. The glycogen and fat will be stored in the liver and adipose tissue, respectively, as reserves for the post-absorptive state. These take the nutrients to the specific cells where the metabolic activity takes place. The absorptive state of metabolism lasts for about four hours, during and after each meal.

Which of the following statement is correct regarding the anabolic reactions that occur during the absorptive state? Fat is also stored in adipose tissue and glycogen in muscle tissue. The major reactions of the postabsorptive state that produce glucose are the following (Figure 25.18): The following reactions dominate during the absorptive state (Figure 25.17): O About 50% of the glucose absorbed from a typical meal is oxidized by cells throughout the body to produce ATP via glycolysis, the Krebs cycle, and the electron transport chain. Hypothermia may be fatal if the core body temperature reaches 37°C or lower.
