Chronic insulin and glucagon deficiencies have been proven to cause hyperglycemia and, therefore, suggesting that insulin is the predominant factor of postabsorptive glucose levels. PostabsorptiveState" "As"the"absorptive"state"comes"to"an"end,"enterocytes"stop"providing"glucose"to"the"hepatic" portal"circulation. Every day a person spends nearly twelve hours in this state. The blood sugar level can become elevated if there are reduced amounts of insulin secreted into the blood (diabetes type I) or the body cells become desensitized to insulin (type II diabetes). During the absorptive state, glucose levels are _____, insulin levels are _____, and glucagon levels _____. During this absorptive state glucose is used by many tissues for energy metabolism. The three major target tissues for insulin are the liver, muscle, and adipose tissue, as shown in Figure 12.2. During the absorptive phase, the body is mainly involved in food digestion. The metabolic adjustments that occur in the body during the switch from postabsorptive to absorptive state are largely triggered by increases in _____ concentration. During fed/absorptive state, glucose is easily available. During the absorptive state, glucose levels are _____ and insulin levels are _____. Insulin is a hormone that allows glucose to enter the cells and be used for energy. The absorptive state of metabolism lasts for about four hours, during and after each meal.

This will come with high levels of nutrients within the bloodstream, and is present 10-30 minutes after a meal. Services, Pancreas: Functions, Anatomy & Insulin Production, Working Scholars® Bringing Tuition-Free College to the Community. In this state glucose concentration in the blood declines and hence insulin levels are also decreased. 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. Most glucose that enters hepatocytes is converted to glycogen. 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. This is the phase directly after eating where food is being absorbed within the digestive system. Excess glucose is stored as glycogen in the liver. Just after eating, blood glucose levels rise and stimulate the release of insulin. Side Effects of Low Insulin Levels. Services, Working Scholars® Bringing Tuition-Free College to the Community. All other trademarks and copyrights are the property of their respective owners. In addition, the liver replenishes its glycogen stores, replaces any needed hepatic proteins , and increases TAG synthesis. The postprandial state generally lasts three to five hours after eating a meal. The absorptive state is referred to as the time after a meal during which the absorption of nutrients takes place. Create your account. Absorptive State Reactions. Which of the following options is correct? Our experts can answer your tough homework and study questions. This allows uptake of glucose into tissues such as the muscle or brain to be used directly for energy. Throughout this state, digested food is converted into sugar or glucose. The plasma glucose concentration is maintained surprisingly constant during the fasting, or postabsorptive, state because of the secretion of glucose from the liver. Post-absorptive plasma glucose concentration has been discovered to be physiologically maintained within the range of 70 mg/dl [3.9 mmol/l] to 110 mg/dl [6.1 mmol/l] in humans. Create your account.

Most cells utilize glucose for fuel. C) adipocytes release fatty acids to the circulation. In the fed state (see Figure 5.6), when there is an ample supply of metabolic fuels from the gut, the main processes occurring are synthesis of reserves of triacylglycerol and glycogen; glucose is in plentiful supply and is the main fuel for most tissues. The high levels of glucose in the absorptive state stimulate the pancreas to release insulin, which lowers the blood glucose levels. Q1) Answers: A. Insulin levels are high. Become a Study.com member to unlock this The absorptive state, or the fed state, occurs after a meal when your body is digesting the food and absorbing the nutrients (catabolism exceeds anabolism). The liver will store glucose or turn any excess glucose into body fat for storage. The Postabsorptive State. The pancreas secretes insulin and glucagon. Fill in the blank: cells secrete somatostatin. The major components of proteins and fat get absorbed by the wall of... Our experts can answer your tough homework and study questions. However, due to the demands of the tissues and organs, blood glucose levels must be maintained in the normal range of 80–120 mg/dL. The postabsorptive state, or the fasting state, occurs when the food has been digested, absorbed, and stored. 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. The digestion of carbohydrates begins in the mouth, whereas the digestion of proteins and fats begins in the stomach and small intestine. - Functions, Hormones & Hypothalamus, Parathyroid Gland: Calcium Metabolism, Osteoclasts & PTH, What is the Small Intestine? In response to the decrease in glucose, insulin levels also drop.

The high levels of glucose in the absorptive state stimulate the pancreas to release insulin, which lowers the blood glucose levels. This is accomplished via increased glucose levels from glucagon and decreased glucose levels from insulin. All rights reserved.

Insulin's major role is to switch the body from a fasting to an absorptive state of metabolism. 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. post-absorptive state: The metabolic state achieved after complete digestion and absorption of a meal. During the absorptive state, glucose levels are high insulin levels are high, and glucagon levels are low. answer! During the absorptive state, a. breakdown of glycogen supplies glucose to the blood. 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.. © copyright 2003-2021 Study.com. 24 - During the absorptive state, glucose levels are...
