Pasina simba hapana hupenyu. Pachena! Isu tinofema, kugadzira, kuita, kuimba. Tinorarama! Kwatiri izvi zvakajairika. Asi simba ratinoshandisa pakuita izvi rinobva kupi? Uye nei tichigona kudzishandisa? Pane here chikonzero nei tichigara takaneta uye tisina basa? Uye chii chatingaita nezvazvo?

Simba remuviri wedu rinobva kupi?

Isu vanhu tine inonzi Simba metabolism (uyewo mafuta metabolism kudanwa). Ichi ndicho chikamu chemetabolism yezvisikwa zvipenyu iyo inoshandiswa kugadzira simba, kusiyana ne zvokuvakisa, iyo inovaka zvikamu zvemuviri uye inopedza simba. Kuti uwane simba, pa chemotrophic Kugadzirwa kwesimba - i.e. muvanhu - makemikari zvinhu zvakashandurwa, zvakasiyana pane mune phototrophic kugadzirwa kwesimba. Zvose zvinoitika nechiedza.

Iyi nzira inotsamira pane akawanda, akaomarara, akarukwa uye anoenderana maitiro, uye hongu zvakare pane zvakasiyana zvinhu. Kana chimwe cheizvi chisipo, chakafanana nejecha mugiya. Hazvisi kuenderera mberi.

Ngatimbofungidzira tichidya apuro kana kuti chimedu chechingwa cheupfu. Enzymes inoputsa chikafu muzvikamu zvayo: mapuroteni, mafuta, makabhohaidhiretsi, mavhitaminzi, zvicherwa uye trace elements. Izvi zvino zvinotora ropa piggyback uye zvinoriunza mumaseru, zvakanyatsojeka: mumitochondria, madiki emagetsi emuviri. Ikoko, makhahydrates (glucose) kunyanya, asiwo mafuta acids, anoshandurwa kuva simba nerubatsiro rweokisijeni.

Zvisinei, muviri haugoni kushandisa simba iri. Inotanga kuchengetwa mumorekuru: adenosine triphosphate, kana muchidimbu: ATP. ATP inounza simba kwarinodiwa - kumamhasuru, kunhengo dzekugaya, kuuropi. Uye tinonzwa kuti: tinofamba, kunyemwerera, rudo uye kurarama.

Asi zvese izvi zvinei chekuita nevhitamini B₁₂ kuita?

B₁₂ uye ropa

Kufanana nechitima chinotakura zvinhu munjanji, ndizvo zvakaita ropa redu. N Kuwanda kwengoro, ndiko kukura kwekufamba kwezvinhu uye nokudaro kuchinja.

Kuti ugadzire masero matsvuku eropa, muviri unoda imwe mhando yevhitamini B, pakati pezvimwe zvinhu₁₂: methylcobalamin. Nekuti inoita basa rakakosha mukukamura maseru uye kuumbwa kweDNA nyowani. Hazvishamisi, saka, kana B₁₂- Kushaikwa hakuenderere mberi. Pane kungoshaikwa kwengoro panzira dzedu dzetsinga.

B₁₂ uye mitochondria

Kana chitima chedu chekutakura zvinhu changosvika kumasero, dambudziko idzva rinomuka. Simba rinobva muchikafu rinofanira kuitwa kuti risvike kumaseru. Nokuti shuga yakachena haina basa kune tsandanyama pakutanga. Vanoda simba mune imwe fomu. Uye ndizvo zvakaita mitochondria.

Mitochondria zvikamu zvidiki zvesero remunhu uye zvinoshanda senge madiki emagetsi emakemikari. Ikoko, zvigadzirwa zvekugaya zvakawanikwa kubva muzvokudya zvinochengetwa mune izvo zvinonzi citric acid kutenderera inoshandurwa kuita mapaketi madiki emagetsi: ATP.

ATP

Adenosine tri-phosphate inoumbwa nezvinotaurwa nezita: adenine (a nitrogenous base), ribose (5-carbon sugar), uye matatu inorganic phosphate mapoka. Apo ATP inopindirana nemvura, boka rephosphate rinoparadzaniswa uye adenosine diphosphate (ADP) uye phosphate inoumbwa. Munguva yekuparadzaniswa uku, simba rinosunungurwa, izvo chaizvo zvatinonzwa uye zvatinosangana nazvo: simba rehupenyu.

ATP+H₂O –> ADP+(P)∆G = -30,5kJ • mol

Iyi nzira inoitika nguva dzose mumaseru edu uye kwete zvishoma. Mamirioni gumi ATP mamorekuru anopedzwa pasekondi uye anoshanda mhasuru sero! Panguva yekushanda kwemhasuru kunesimba, sero retsandanyama rinoshandisa kupihwa kwaro mumasekonzi mashoma.

Kuti ugadzire ATP, matanho emakemikari akasiyana anodiwa: iyo citric acid kutenderera. Zvinhu zvinoshandurwa, kushandiswa, kuchinjwa kuburikidza nekushandiswa kwavo uye kushandiswa zvakare. Pakupedzisira, ATP inoumbwa. Uye kuti izvozvo zvishande vhitamini B₁₂ yakakosha se "cog" diki asi yakakosha mune iyi yakaoma makemikari mashandiro. Asi kwete izvozvo chete.

Creatine, carnitine uye coenzyme Q10

Zvinhu zvitatu zvakakoshawo pakupa muviri simba: Creatine, carnitine uye Coenzyme Q10. Creatine inobatanidzwa mu "recharging" ADP nesimba. Carnitine inosunga kumafuta asidhi uye inoaendesa kune mitochondria kuti igadzirwe kuita simba. Uye coenzyme Q-10 inodiwa kugadzira ATP. Kuti ugadzire zvitatu izvi, muviri unoda methylcobalamin padanho rakakosha repakati - iyi uye hapana imwe.

Vitamini B₁₂ - mubatsiri mudiki, mhedzisiro yakakura

Kana isu takaneta uye tisina basa, panogona kuve nezvikonzero zvakawanda: kushaikwa kwezvinovaka muviri, chepfu kana hutachiona ndezvimwe zvacho. Asi zvinogona zvakare "kungove" kushaikwa kweiyi isingaonekwi mubatsiri wepasirese: vhitamini B.₁₂.

Asi chenjera! Zvechokwadi, kudonha kwekuita hakugoni kukonzerwa nevhithamini imwe kana maviri B₁₂-Gadzirisa zvipo, nekuti vhitamini B₁₂ haisi mushonga wakafanana nekofi, asi chikafu. Nenguva yakareba, yenguva dzose yekutora, zvisinei, iwe unogona kunyatsonzwa mhedzisiro, nekuti inodzikamisa uye inowedzera simba resimba munguva refu.

Wand yaMwari

Uye chinhu chinoshamisa pazviri ndechekuti: Mwari anopa hupenyu simba! Asi haavapi mashiripiti wand, asi kuburikidza zvachose, yakaoma kwazvo, yakanyatsogadziriswa maitiro emakemikari. Uye neimwe nzira nenzira inoshamisa kwazvo.
