During the absorptive state, anabolic reactions are favored. Carbohydrates are first used for ATP synthesis with excess stored as glycogen or triglycerides in the adipose tissue. Excess amino acids and dietary fat are also converted to triglycerides and stored. During the postabsorptive state, metabolism shifts to favor catabolic reactions.

Check All That Apply The postabsorptive state is solely under endocrine control. Glycogenolysis and gluconeogenesis are promoted by glucagon. The parasympathetic nervous system promotes lipolysis. Under neural control, energy storage is favored during this time. Growth hormone may be secreted to aid in elevating blood-glucose levels.

6 FAQs about [Under neural control energy storage is favored during postabsorptive]

What occurs during the absorptive state?

During the absorptive state, nutrients may be used immediately to meet energy demands. -Glycogenolysis is most likely utilized to meet energy demands during the postabsorptive state. -Gluconeogenesis most likely occurs at least 4 hours after the last meal. Nutrients are absorbed and utilized for energy during the absorptive state.

What is a postabsorptive state?

Figure 1. Absorptive State. During the absorptive state, the body digests food and absorbs the nutrients. 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.

What happens during a postabsorptive state?

During the postabsorptive state, the body must rely on stored glycogen for energy. When the body is deprived of nourishment for an extended period of time, it goes into “survival mode.” The first priority for survival is to provide enough glucose or fuel for the brain. The second priority is the conservation of amino acids for proteins.

What is the absorptive and fed state?

Distinct mechanisms are in place to facilitate energy storage, and to make stored energy available during times of fasting and starvation. 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).

What is the absorptive state of energy metabolism?

When nutrients such as glucose and lipid are being absorbed, and their concentrations in the blood are high, the pattern of energy metabolism is known as the absorptive state. In this state, a fraction of the blood glucose is used by various tissues to meet their immediate energy needs.

Where is glucose stored during absorptive phase?

In summary, during the absorptive phase, glucose is used for energy production by most tissues of the body, and the excess is stored in muscle and liver as glycogen, and in adipose tissue as fat. These relationships are outlined in Figure 9.1.
