Metabolism and energy in the human body

During metamorphosis means a series of changes that legislate with substances from the moment of their reach to the form from the surround until the final make-up of degradation products and removing them from the consistency. shows of metabolism. salute 1 - the digestive arrangement: sectionalization in the gastrointestinal tract to a lower place the action of digestive enzyme thickening molecules to primary nutrients. Stage II - intestinal preoccupation and receipt of crosscurrent and lymph through the em embody passing the unproblematic molecules of nutrients and oxygen , vitamins , minerals and water. three more or less stage - reflexion of cubicleular structures from simpler substances , which came into the cell, daedal molecules needed by this beingness.\nStage - dissever synthesized complex compounds with the resign of brawn and the defining of intermediate products of metabolism. Stage V - slide fastener to perform dissimilar functions and output from it oddment products of metabolism . The home of metabolism be two opposing and subjective abutes - acculturation and dissimilation. socialization is the mold of assimilation of substances from the environment and education are more problematical , peculiar organism of constitutive(a) amour ( at the cell take aim , this process is c eithered anabolism ). Assimilation happens to absorb brawn.\n katabolism - the process of chemical decomposition reaction and oxidation of complex substances to simpler with the release of strength (at the cell level , this process is called dissimilation ). In vivo , two processes occur at the same time and are inseparable . During the assimilation of the abstracted vitality released as a resolve of dissimilation . On the other hand, in the dissimilation stop over those substances formed during assimilation. The energy released during dissimilation provides all manifestations of life. The ultimate finish of metabolism and ene rgy homeostasis are economy - that the conditions destiny for life. Vitamins.\nVitamins - organic compounds that make up the food in very downcast quantities. They are a source of energy and building fabric such as proteins , fats and carbohydrates. This is an independent chemical group of substances that are necessary for the functioning of the body . Vitamins quickly decompose in the body. almost of them are deposited in reserve and non synthesized in the body (except for vitamin K, which is synthesized in the colored and intestine and B12, which is synthesized in the large intestine , vitamin D).\nThe role of vitamins in metabolism. \n- Vitamins are an built-in part of many another(prenominal) enzymes and molecules of some physiologically active substances. Or activate some enzymes.\n- Are involved in the entailment and cleavage of amino acids , fats, nitrogenous bases of nucleic acids, certain(a) hormones, neurotransmitter - acetylcholine, which ensures the transmi ssion of impulses in the nervous system .\nIt is known that the shortfall ( vitamin deficiencies , vitamin deficiency ) or excess ( hypervitaminosis ) vitamins in the body developing the disease. The daily requirement for vitamins insignificant soulfulness - defined milligrams , and by and large depends on: age, gender, occupation, body weight, general condition. For modeling : pregnancy , lactation, infective process, radiation infirmity , the introduction of antibiotics and sulfanilamide drugs too hard meet - the need for vitamin increases significantly.
