Izitshalo CO2 kudingeka senzeni? Kanjani ukufakazela isidingo CO2?

Ngokwesiko kubhekwa ukuthi sokusinda eziphilayo kudingeka umoya-mpilo. Ngakho-ke, kwaba isimanga ngokwanele ukuba ufunde isihloko esithi "CO2 edingekayo ukuze izitshalo ...". Impendulo yalo imfumbe, bheka ngezansi.

Carbon dioxide futhi izakhiwo zalo

Carbon dioxide, i-carbon anhydrite, carbon dioxide - angamagama ayinto efanayo. Kuyinto owaziwa-carbon dioxide. Ngaphansi kwezimo ezivamile, yalolu ketshezi lisasesimweni gaseous, kuyilapho alinaso umbala noma ukuhogela. Lapho izinga lokushisa komoya lehliselwa, isikhutha osemanzi futhi iba mhlophe. Kulesi ukuguqulwa, ubizwa ngokuthi "iqhwa". Lena ngokwanele izidakamizwa amakhemikhali asebenzayo. Carbon dioxide ixubana izinsimbi, oxides lezisekelo. Umzimba womuntu ungakwazi ukwakha i egcekeni engazinzile nge-hemoglobin egazini, njenge-mpilo. Kusukela exchange igesi Kwenziwa esebenzisa isimiso sokujikeleza kwegazi. Akukhona ezinesihlungu, kodwa at lokuhlala eliphezulu kungokwalabo amagesi anobuthi.

Emvelweni, yakheke ke ngenxa emishinini yokuphefumula eziphilayo elibi futhi amandla omlilo. I gaseous carbon dioxide siphela emanzini. Yingakho, kungenzeka ukukhuluma mayelana izinhlelo CO2 supply okugcinwa nezitshalo ulwelwe isidingo ukuphila okuvamile. It has carbon dioxide futhi ukubaluleka ezimbonini. It is kabanzi embonini ukudla njengendlela agent uwohloka futhi uyalondoloza. In the state ketshezi ligcwele mlilo futhi othomathikhi uhlelo umlilo-zokucisha.

Kuyini i-photosynthesis

Okokuqala, CO2 kuyadingeka ngoba ukugeleza izitshalo kuyinto inqubo ebalulekile anehlathululo kwamaplanethi - photosynthesis. Ngokuhamba yayo eziningana ezibangela wezinto kwakhiwa glucose carbohydrate. Kwaba izitshalo zakhe ukusetshenziswa ukudla, ukukhula nokuthuthuka kanye nezinye izinqubo ezibalulekile. Ngaphezu kwalokho, omunye umkhiqizo okunjena mpilo - isimo esiyinhloko ukuba khona zonke izidalwa eziphilayo emhlabeni, ngoba kubalulekile ukuba ukuphefumula. Negesi lokushintshisana in izitshalo kuyinto Sibonga kungenzeka ukuba khona kule enamathela lendwangu indlela okwakheke ngayo Leaf ekhethekile - stomata. Ngamunye wabo siqukethe amaphiko amabili. Ngaphansi kwezimo ezithile, basuke ivaliwe futhi ivulekile. Ngabo kwenzeka nokudilivela umoya-mpilo ne-carbon dioxide.

Imigomo nesenzakalo ye-photosynthesis

Photosynthesis kwenzeka kuphela izakhiwo ezikhethekile kanye nobukhulu bezinhlamvu main leaf izicubu. Ziyakwazi ngokuthi chloroplast. okuqukethwe yabo yangaphakathi ethulwa stroma futhi thylakoids gran, okuyinto a colorant - sombala i-chlorophyll. Unika Kwezinye izingxenye oluhlaza isitshalo. Ngo horoplastah photosynthesis kwenzeka kuphela ngaphansi kwezimo ezithile. Kuyinto khona kwelanga, amanzi nesikhutha. A yi okunjena kumakhemikhali kumiswa izinto eziphilayo-glucose ne-oksijini igesi. Eyokuqala wabo - umthombo wokuphila izitshalo ngokwabo, kanti eyesibili isebenzisa ezinye ukuphefumula. Le nqubo anehlathululo kwamaplanethi.

Carbon dioxide futhi izitshalo

Kanjani ukufakazela isidingo CO2? elula kakhulu. Njengoba carbon dioxide ukhululeka emvelweni ngenxa emishinini yokuphefumula, ukuntula yaso ngokwemvelo is hhayi waphawula. Nokho, amanzi aquarium kwakungenjalo kakhulu ngenxa zinhlobo ukwehluka ezincane eziphilayo. Ngakho-ke, uma izilungiselelo ekhethekile engasetshenziselwa kokunikeza carbon dioxide, ngokuhamba kwesikhathi senani alwanele ngoba ukugeleza olunzulu ye-photosynthesis. Phela, CO2 kuyadingeka ukuba izitshalo akhiqiza izakhi zabo. ukuthengisela esifike ngesikhathi futhi okuqhubekayo kwe-carbon dioxide emanzini kuyoba isimo tank yakho ugcwele ulwelwe aluhlaza futhi ezimibalabala.

izitshalo negesi kudingeka uphefumule: ukubaluleka komoya-mpilo

It kuvela ukuthi ngenxa izitshalo zabo ukuphila ukukhiqiza umoya-mpilo esikhundleni iyavuleka ke. Khona-ke kuphakama umbuzo: Ingabe bona siphefumule kanjani, futhi ngokuvamile kuba khona uma unayo inqubo namachibi futhi eqhekeza izinto eziningi eziphilayo? Yiqiniso, njengazo zonke ezinye izinto eziphilayo, basebenzisa oxygen efanayo. It kuvela ukuthi ngo izitshalo zenzeka kanyekanye ezimbili inqubo cishe okuphambene. It photosynthesis nokuphefumula kwezimila. Ngamunye wabo kuyadingeka ukuze uthole ukuphila okuvamile zalesi sihlahla.

Photosynthesis nokuphefumula kwezimila: yini ebaluleke ngaphezu kwalo

Plant ubunjalo itholakala iqiniso ukuthi kukhona nowukuphela kwakhe ophilayo kokuba ayinabantu, nesikhathi oxygen ne-carbon dioxide cishe kanyekanye. Kodwa lokhu akusho ukuthi siba yingozi futhi akufanele ibekwe endaweni yokuhlala. Into wukuthi izitshalo akhiqiza i-oksijini okuningi kuka-carbon dioxide.

Ukuze hhayi abaphazamisa lokhu ukulinganisela yemvelo, udinga kuhambisana nemibandela yalezi zinhlelo. Ngokwesibonelo, uma egumbini kanye izitshalo engakutholi ukukhanya kwelanga, inqubo ye-photosynthesis kwenzeka. Kulokhu, ukwakheka glucose sithule. Kodwa inqubo ukuphefumula uyaqhubeka. semali carbon dioxide ukuqongelela emoyeni. Kulokhu, izitshalo bangaba yingozi. Ngenxa yalokho, zombili lezi izinqubo ezibalulekile. Kuphela ngenxa izitshalo-mpilo ukuphefumula, futhi ngosizo carbon dioxide umkhiqizo ne-glucose okuphakelayo.

Ngakho, CO2 idinga izitshalo ngenqubo ngokukhiqiza organic compounds - photosynthesis, okuyinto ebalulekile isikali kwamaplanethi.
