False. 9.1) and converted to ketoacids that are oxidized via the citric acid cycle and other pathways. 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. Amino acids and fats are used to form degraded protein, and small amounts are used to provide ATP. D) A and C e) all of the above of energy storage molecules and other processses characteristic of the absorptive state : Term. Triglycerides - Chylomicrons, the main product of fat digestion, are first broken down to fatty acids and glycerol through hydrolysis using Lipoprotein lipase. I. OVERVIEW OF THE ABSORPTIVE STATE. 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. In a low carb environment, other body cells will also begin to use triglycerides as energy sources. During this state glucose is the most important energy fuel. Throughout this state, digested food is converted into sugar or glucose. The major reactions of the postabsorptive state that produce glucose are the following (Figure 25.18): 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. (a) taurine (b) alanine (c) leucine (d) lysine A protein-sparing shift in metabolism from gluconeogenesis to lipolysis occurs during the (a) early fasting state (b) fasting state (c) starvation state (d) fed state How long does it take for the postabsorptive sate to evolve into the fasting state? 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 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.

Which of the following occurs during the post-absorptive state (after food has been digested)? They may also be converted to fat stores. The digestion occurs with the help of enzyme activity and then the nutrients directly enter the body fluids. 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. B.- During the absorptive state, the main fuel for energy is provided by the anabolic reactions or beta-oxidation of fatty acids . The rest is used for energy in adipose cells, skeletal muscles, and hepatocytes. Check out a sample Q&A here. 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). During the absorptive state, anabolic processes use glucose in a variety of ways.

B. is when glycogenolysis usually occurs. The main components through which the nutrients can pass include the blood and lymph. 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. 52. Sciences, Culinary Arts and Personal The fuel used for this process is glucose. The liver is the first port of call for these absorbed nutrients. Create your account.

The main components through which the nutrients can pass include the blood and lymph. Amino Acids - The liver deaminates amino acids to keto acids to be used in the krebs cycle in order to produce ATP. Following a glucose load, the body assumes an absorptive state, and its metabolic profile is primarily regulated by insulin.

Glucose is also carried in the bloodstream to cells where it will be used to provide energy for cellular processes. The glucose then travels to the blood or is converted to glycogen and fat (triglyceride). People have an overall metabolism that differs from the metabolism of individual cells. It takes up a large fraction of the nutrients, thereby altering the composition of the blood before it circulates to the rest of the body. 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). Multicellular organisms such as animals and plants do as well. During the absorptive state, our body digests foods and absorbs nutrients into the blood.

An absorptive state occurs during the period within four hours of food consumption. Services, Digestive System II: The Lower Gastrointestinal Tract, Working Scholars® Bringing Tuition-Free College to the Community. The absorptive (well-fed) state is the 2- to 4-hour period after ingestion of a normal meal. 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). When a person is active, most of the body heat is generated in the brain, heart, and endocrine glands. In the absorptive state, a fraction of the absorbed amino acids is taken up by the liver (Fig. Glycolysis; the citric acid (Krebs) cycle. The remaining glucose is taken in for use by body cells or stored in skeletal muscle as glycogen. Euglycemia occurs when the rate of glucose utilization parallels the rate of glucose production or absorption. Some are used to make plasma proteins, but most leave through liver sinusoids to be used by body cells to construct proteins. Absorptive state is the period in which the gastrointestinal tract is full and the anabolic processes exceed catabolism.
