Muviri

Muviri - muitiro zvikuru kunzwisisa. It kunoratidzwa ne Implementation kuchinja muviri namakemikari zvinoriumba. Izvi zvinobatsira kuti basa, kukura, kubudirira uye upenyu muviri rose. Shona, kurondedzera muviri, akati kuti ichi ndicho chiratidzo chikuru choupenyu, uye wairatidza kuti pamwe kugumiswa kwacho achamira uye upenyu. Mukutaurirana kwemakemikari zvinoriumba yakabereka simba zvakakodzera kuti rutsigiro upenyu.

Muviri, sezvo inozivikanwa, chinosanganisira pakatarisana maviri pezvakaitwa kuitika panguva imwe nguva.

Dissimilation (catabolism) unotora maitiro zvigadzirwa zvinobva kuna disintegration, zvichiteverwa oxidation uye deducing kuora zvinoriumba. Kuitwa (anabolism) rinoreva zvose zvinoitwa kuti chokuita kwetunhu kuMudzidzisi zvinhu muviri uye avo kuitwa uye chikumbiro nokuda kukura, kukura, basa.

Muviri - zvakaoma simba uye nokukanganisika urongwa, izvo anopa kushandisa zvinhu zvokudya zvinodiwa muviri, zviso kudiwa simba uye epurasitiki zvigadzirwa.

Munguva zvomudumbu hurongwa, zvinhu (makabhohaidhiretsi, mafuta, mapuroteni nezvimwewo yakakwirira samolecular uremu yeimwe) vari rwakakamukana nyore yeimwe (yakaderera samolecular uremu). Recent pashure kupinda muropa uye zvinyama vari pasi nekutambira transformations: oxidative phosphorylation, uye dzimwe Kurovedza oxidation.

Zvinofanira kucherechedzwa kuti neimwe muviri mhenyu kuitika siyana nokukanganisika kwendangariro. In asiri mupenyu miviri kunoitika kuzvitsinhanisa kwemaatomu uye mamorekuru, vomumatunhu avo.

In kuitisa zvidzidzo pakatanga tracer kumhuka zvakanga vakawana kuti zvose metabolic pezvakaitwa mumasero uye nyama kuitika mberi. It haitauri chero constraints pakati "simba" uye "kuvakwa" pamusoro morekuru. sangano ravo riri zvakaenzana chikuru muviri.

Rakavakwa kuti paavhareji hafu zvinyama zvose dzevanhu mapuroteni anochinja ose mazuva masere. Chiropa makemikari (nokuti muviri ichi dzinoratidzwa kupfuura zvikuru siyana) vari yoku- maawa maviri kana mana ose. Pane zvimwe zvinhu izvo reserved kuitika ose makumi mashoma maminitsi.

Metabolic pezvakaitwa vanopa simba nepakati gadziriro sezvo chipenyu muviri. Pakupfuura iri kwetunhu nokuparadzwa, kuparadza uye kubereka akadzikama. muviri Wrong anenge kusaenzana. Izviwo, kunotungamirira zvirwere zvomukati uye hurongwa.

Hwaro metabolic siyana vanoumba nesungano pakati mamorekuru uye maatomu pamusoro physico-makemikari pamwero. ukama Izvi pasi mitemo zvakafanana zvipenyu uye muzvinhu zvisina upenyu.

Metabolic pezvakaitwa zvakabatana chaizvo pamwe kupanana simba. Zvipenyu vanoonekwa akazaruka gadziriro (maererano simba). Zvichienderana svikiro yakapoteredza muviri mukati, (muviri) rinowanika inotungamirwa simba. Saka, kuvapo kunosimbiswa kana kuramba simba mazano kubva kunze.

Nokuti munhu uye mhuka chikuru simba bhuku iri kwezuva nemwaranzi. Nokuda kwayo dzokupisa kunoitika uye dzidzo kudya kunovaka.

The zvokudya zvakasiyana-siyana uye kunzwisisa sezvamunoita. Most ari makuru zvinovaka muviri - macronutrients. Izvi zvinosanganisira makabhohaidhiretsi, mafuta, mapurotini. Zvokudya varipowo uye chicherwa zvinoriumba (macronutrients). Izvi zvinosanganisira yavaibvisa, phosphorus, calcium nevamwe. Present nezvokudya uye chiya chisingadiwi zvinhu: selenium, manganese, ayodhini, zingi, cobalt, mhangura uye nevamwe. Pamwe chete mavhitamini zvicherwa nhengo boka micronutrients.
