Figure 24.5.1 – Absorptive State: During the absorptive state, the body digests food and absorbs the nutrients into cells. A post-absorptive state is a metabolic period that occurs when the stomach and intestines are empty. Fill in the blank: cells secrete somatostatin. Insulin is released from the beta cells of the pancreas after intake of food. This is the phase directly after eating where food is being absorbed within the digestive system. This state is typically reached four or more hours after food has been consumed, usually overnight and in the morning before breakfast. Following a meal we enter an absorptive state in which ingested nutrients such as glucose enter the blood from the GI tract. 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. Feeding – During meals, insulin levels are raised. High levels of glucose and amino acids in the blood (as when a meal is being processed) are the primary stimuli for insulin … A number of nutrients in the blood can stimulate its release.

So after eating a substantial meal, you have plenty of glucose, which is the main source of garbine. 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). Create your account. During the absorptive state, the body digests food and absorbs the nutrients. Insulin promotes glycogen synthesis in … The Postabsorptive State. 24 - Fever increases the body temperature and can... Ch. 24 - The postabsorptive state relies on stores of... Ch. The release of insulin into the blood is stimulated by eating and inhibited by fasting, and insulin is largely responsible for promoting the pattern of metabolism seen in the absorptive state. Most cells utilize glucose for fuel. Excess glucose is stored as glycogen in the liver. The high levels of glucose in the absorptive state stimulate the pancreas to release insulin, which lowers the blood glucose levels. Just after eating, blood glucose levels rise and stimulate the release of insulin. 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. Absorptive State Reactions. absorptive state kicks in your body, especially after you've eaten a substantial meal.
