During the absorptive state, glucose levels are ________, insulin levels are ________, and glucagon levels ________. Absorptive State Reactions. post-absorptive state: The metabolic state achieved after complete digestion and absorption of a meal. 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).

Key Terms. b. glucagon secretion is high. The metabolic adjustments that occur in the body during the switch from postabsorptive to absorptive state are largely triggered by increases in _____ concentration.

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 absorptive state, or the fed state, occurs after a meal when your body is digesting the food and absorbing the nutrients (anabolism exceeds catabolism). PostabsorptiveState" "As"the"absorptive"state"comes"to"an"end,"enterocytes"stop"providing"glucose"to"the"hepatic" portal"circulation. A post-absorptive state is a metabolic period that occurs when the stomach and intestines are empty. 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. Following a meal we enter an absorptive state in which ingested nutrients such as glucose enter the blood from the GI tract. During the absorptive state, a. breakdown of glycogen supplies glucose to the blood. answer! Most cells utilize glucose for fuel. Insulin's major role is to switch the body from a fasting to an absorptive state of metabolism. Excess glucose is stored as glycogen in the liver. This allows uptake of glucose into tissues such as the muscle or brain to be used directly for energy. The high levels of glucose in the absorptive state stimulate the pancreas to release insulin, which lowers the blood glucose levels. view the full answer view the full answer During the absorptive phase, the body is mainly involved in food digestion. Glycogen and triglyceride storage slows. - Function, Enzymes & Role in Digestion, Physiology of the Stomach and Gastric Juices, Pineal Gland, Functions, Melatonin & Circadian Rhythm, Exocrine vs Endocrine Glands: Medical Terms, Anatomy of the Spinal Cord: Function & Explanation, Hormones of the Testes and Ovaries: Functions & Anatomical Features, UExcel Pathophysiology: Study Guide & Test Prep, CSET Science Subtest II Life Sciences (217): Practice & Study Guide, Anatomy and Physiology: Certificate Program, High School Biology: Homework Help Resource, SAT Subject Test Biology: Tutoring Solution, Microbiology Syllabus Resource & Lesson Plans, Biological and Biomedical -Insulin is secreted from the beta cells of the pancreas, this is triggered by increased blood glucose and amino acids-GLUT 2 channels are responsible for beta cell glucose uptake-elevated levels of glucose within beta cell causes membrane depolarisation (thought to be caused by metabolism of glucose to alter ADP:ATP ratio thus causing altered membrane conductance) Side Effects of Low Insulin Levels. All other trademarks and copyrights are the property of their respective owners. Just after eating, blood glucose levels rise and stimulate the release of insulin. During fed/absorptive state, glucose is easily available. The Postabsorptive State. 60) During the absorptive state, A) skeletal muscle fibers release glucose. During a post-absorptive state, the body's energy needs are fulfilled from energy previously stored in the body. Q1) Answers: A. Insulin levels are high. All rights reserved.
