Answer:

response allergens are only active seasonally and are generally harmless to the body.

Explanation:

Allergens differ from antigens because response allergens are only active seasonally and are generally harmless to the body. Allergens often produce an abnormally large immune response to what is an otherwise harmless particle. Examples are dust, royal jelly, pollen and pet dander.

Answer:

Allergens differ from antigens because *they do no stimulate the immune system resulting in the production of leukocytes rather than the stmulate the IgE antibodies*

Explanation:

Allergen and antigen are both foreign substances that can cause certain disorders to animals, but there is some difference between them in terms of their nature and the diseases caused by them. An allergen is a nonparasitic foreign substance that can cause certain immune reactions in the body when it enters the body.  Whereas, an antigen is a foreign substance that can trigger the immune system to produce a specific immune response. This immune response leads to produce antibodies that can neutralize or destroy the foreign substances that entered the body.

Allergens can produce Systemic Allergic Response. Allergens stimulate the IgE antibodies by binding to them on the mast cells and causing the mast cells to rupture and release histamine, serotonin, and heparin, initiating inflammatory response.

Consider a series of metabolic events during fasting. Within a few days after a fast begins, nitrogen excretion accelerates to a
timurjin [86]

Answer:

A series of events occur, in prolonged fasting; the body undergoes changes and adaptations of its metabolism to continue to meet energy needs and maintain vital functions, despite not receiving food

These changes are divided into three phases according to the elapsed days of fasting and according to the metabolic processes involved.

First phase: main consumption of reserve carbohydrates.

Second phase: main consumption of fats.

Third phase: serious consumption of proteins.

Explanation:

If the fast is prolonged in time, the metabolic processes change in their qualitative and quantitative characteristics, so that the energy products consumed (glucose, free fatty acids and ketone bodies) are modified, their oxidation decreases globally and after the initial depletion of hepatic and muscular glycogen and protein catabolism, the main source of glucose is the liver through gluconeogenesis. The substrates initially come from protein catabolism and lipolysis, but later protein destruction slows down, maximizing lipolysis.

Between the first phase and the second phase of the fast some muscle proteins are lost but not excessively, even with fasts of two or three weeks.

After about 2 weeks of fasting, up to two-thirds of the energy the brain needs is obtained from ketone bodies. These ketone bodies are the breakdown products of fats and are responsible for the typical ketone breath reminiscent of the smell of acid apples; urine also smells like ketone.

In this phase, damage begins to occur in some important organs such as the liver and kidneys. Starting the first week of fasting, acidosis affects the heart's function of the circulation and the brain.

In the third phase of the prolonged fast it happens from 3 weeks, that is, about twenty days without food, although it varies according to the constitution of each person. A peak of muscle protein consumption occurs and a great loss of weight begins to be perceived with great weakness. Edema occurs and albumin concentration in the blood is altered, as a sign of the self-digestion of muscle proteins.

From approximately 30 days of fasting, the state of malnutrition severely affects all body systems. After forty or fifty days the deterioration is noticeable due to physical wear, the person loses his mobility and suffers from unconsciousness. Finally, starvation death can occur from cardiorespiratory arrest or from lack of blood supply to the brain.
