This state is typically reached four or more hours after food has been consumed, usually overnight and in the morning before breakfast. B) insulin levels are low. 24 - Fever increases the body temperature and can... Ch. The high levels of glucose in the absorptive state stimulate the pancreas to release insulin, which lowers the blood glucose levels. During the absorptive state, the body digests food and absorbs the nutrients. Absorptive State Reactions. Our experts can answer your tough homework and study questions. During a post-absorptive state, the body's energy needs are fulfilled from energy previously stored in the body. The three major target tissues for insulin are the liver, muscle, and adipose tissue, as shown in Figure 12.2. During the absorptive state, glucose levels are _____, insulin levels are _____, and glucagon levels _____. The major components of proteins and fat get absorbed by the wall of... Our experts can answer your tough homework and study questions. A post-absorptive state is a metabolic period that occurs when the stomach and intestines are empty. Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. © copyright 2003-2021 Study.com. Insulin's major role is to switch the body from a fasting to an absorptive state of metabolism. Insulin is released from the beta cells of the pancreas after intake of food. During the absorptive phase, the body is mainly involved in food digestion. 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. © copyright 2003-2021 Study.com. The postprandial state generally lasts three to five hours after eating a meal.

Following a meal, the body is in an absorptive state and there will be high levels of free glucose, 1 comment corrections: The answer should be high; high. In this state glucose concentration in the blood declines and hence insulin levels are also decreased. Fill in the blank: cells secrete somatostatin. The absorptive state is referred to as the time after a meal during which the absorption of nutrients takes place. Services, Pancreas: Functions, Anatomy & Insulin Production, Working Scholars® Bringing Tuition-Free College to the Community. Body mostly depends on glycogen stores. The absorptive state is primarily an anabolic state; that is the majority of reactions involve synthesis of ... During the absorptive period, plasma glucose levels do what: Definition. Insulin is a hormone that allows glucose to enter the cells and be used for energy. 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. Most cells utilize glucose for fuel. B. All other trademarks and copyrights are the property of their respective owners. During the absorptive state, a. breakdown of glycogen supplies glucose to the blood. Every day a person spends nearly twelve hours in this state.

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. Sciences, Culinary Arts and Personal However, glucose is the most important one. The Jews are broken down to make energy in the cell. The metabolic adjustments that occur in the body during the switch from postabsorptive to absorptive state are largely triggered by increases in _____ concentration.

Figure 24.5.1 – Absorptive State: During the absorptive state, the body digests food and absorbs the nutrients into cells. 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.
