What are the islets of Langerhans? 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. 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. During a post-absorptive state, the body's energy needs are fulfilled from energy previously stored in the body. Answer to: During the absorptive state, glucose levels are and insulin levels are. Insulin stimulates the synthesis and storage of glycogen in myocytes. The pancreas secretes insulin and glucagon. 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 pancreas plays an important role in digestion... Insulin functions to: O decrease blood... Insulin is taken up by endocytosis by endothelial... Insulin does all of the following: 1. In this state glucose concentration in the blood declines and hence insulin levels are also decreased. Create your account. Figure 24.5.1 – Absorptive State: During the absorptive state, the body digests food and absorbs the nutrients into cells. During the absorptive state, glucose levels are _____ and insulin levels are _____. the insulin should bind to the glucose … Absorptive State Reactions. During the absorptive state, glucose levels are high insulin levels are high, and glucagon levels are low. However, glucose is the most important one. The high levels of glucose in the absorptive state stimulate the pancreas to release insulin, which lowers the blood glucose levels. The correct answer is d.: During the absorptive state, glucose levels are high insulin levels are high, and glucagon levels are low. answer! high; high; are low Starvation sets in after 3 to 4 days without food.

Chronic insulin and glucagon deficiencies have been proven to cause hyperglycemia and, therefore, suggesting that insulin is the predominant factor of postabsorptive glucose levels. 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 three major target tissues for insulin are the liver, muscle, and adipose tissue, as shown in Figure 12.2. Glycogen and triglyceride storage slows. So after eating a substantial meal, you have plenty of glucose, which is the main source of garbine. - Functions, Hormones & Hypothalamus, Parathyroid Gland: Calcium Metabolism, Osteoclasts & PTH, What is the Small Intestine? 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. © copyright 2003-2021 Study.com.

As glucose levels from the GI tract start to fall, so does the concentration of insulin in blood. Insulin is released from the beta cells of the pancreas after intake of food. view the full answer view the full answer 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 plasma glucose concentration is maintained surprisingly constant during the fasting, or postabsorptive, state because of the secretion of glucose from the liver. The Post absorptive state is also known as fasting state. The Postabsorptive State. The high levels of glucose in the absorptive state stimulate the pancreas to release insulin, which lowers the blood glucose levels. During fed/absorptive state, glucose is easily available. ....
