Kanjani izitshalo esiwuhogelayo wona? cwaningo Engokoqobo Yezindaba udaba

Kwatholakala ukuthi ukusabela kwamakhemikhali okwenzeka kubantu nasezilwaneni ngokufanayo. Ingabe izitshalo esiwuhogelayo wona? Ngokuhamba ucwaningo lo mbuzo, abacwaningi wanikeza impendulo enhle. Oxygen kuyadzingeka namachibi izinto eziningi eziphilayo. Ngakho kukhona ukukhululwa kwe amandla okuyinto eziqukethwe molecule. Kodwa uma umuntu umlomo, emaphashini, ekhaleni, lapho umoya-mpilo emzimbeni, njengoba izitshalo esiwuhogelayo wona? Mayelana nalesi kamuva esihlokweni.

Uhlolojikelele

emkhathini woMhlaba endulo bancishwa umoya-mpilo. Nokho, i-carbon dioxide bekulokhu impela eningi. Ngokuhamba kwemvelo, izitshalo baye bahlakulela ikhono ukukuqonda. Ngenxa yalokho, amandla elangeni siguqulelwa izakhamzimba., Futhi ukukhulula umoya-mpilo emkhathini, okuyinto wanikela ngokuphila ezinye izinto eziphilayo. Omunye ucwaningo lokuqala lapho kwatholakala kanjani izitshalo ukuphefumula, kwadingeka nakho beet kanye iklabishi. Okokuqala, isiko likhule ngaphandle. Khona-ke, ingxenye yazo afakwe egumbini lapho okuqukethwe mpilo mayelana 2.5%. Enye ingxenye wahlala emoyeni, lapho O ₂ kwaba 21%. Ukukhanyisa nalabo, kanye nabanye eyenziwa ubusuku nemini. Kwakuthinta babecabanga ukuthi izitshalo esitokisini Uzofa umoya-mpilo. Nokho, ezinsukwini eziyisithupha kamuva, isisindo sabo kwaba kakhulu kunaleyo labo abasala ku emoyeni. Kanjani izitshalo ukuphefumula ngaphandle oksijini? On lokhu kamuva.

Njengoba izitshalo uhogele ukukhanya ebumnyameni?

Iqiniso lokuthi abamele flora bakwazi kahle kakhulu lekusebentisa emandla elilanga. Phezu okuvela ebumnyameni kwenzeka ngendlela ethile "inkinobho" komunye umthombo kwenye. Njengoba izitshalo uhogele ukukhanya ebumnyameni? On yokuvuma amandla elanga kwenzeka Kuhlanganisa organic compounds. Phezu okuvela ebumnyameni kwenzeka namachibi compounds. Kulo mBhalo sikhuluma "amnyama" umoya, futhi owokuqala - kwi "ukukhanya". Ikhono okwesikhathi inkinobho enjalo ikuvumela ukuba ugcine yasekhaya amandla izinqolobane. Kodwa abameleli flora uhogele ukukhanya, kodwa inqubo akuwenzi ezinhle. Ukudla izitshalo-mpilo ikhiphe i-carbon dioxide. He is ukudla zabo eziyinhloko. Kule ndaba, ukukhula ehlile kancane. Nokho, Kukhona futhi abameleli abanjalo ye izitshalo, okungadingi liphazamisane ukuthuthukisa ukukhanya. ukuphefumula Khanyisa, isibonelo, akudingeki umoba kanye corn.

Izimbangela ukuphefumula ukukhanya

Kusukela njengoba ososayensi lokucabanga, kwaba Symbiosis eziphilayo photosynthesis nge bakudala-non-photosynthesis. Ngaphansi Symbiosis bona iqhaza mutual inqubo, okuyinto ezuzisa zombili izinhlangothi. kuhlezi elincane amanzi photosynthesis ugxile isikhutha imvelo, ngaleyo ndlela umoyampilo. Uma akubanga ukuphefumula, iyavuleka mayelana ₂ eziphilayo ezitholakala imvelo, ngokuba photosynthesis izodala izimo okungabekezeleleki. Kodwa ngokuhamba kwemvelo ezisekhona nalabo abamele emhlabeni organic ezaziyincithakalo kancane wusizo nefotosintetikov.

Omunye compounds, ezakhiwe photosynthesis okuyinto, kuyinto glycolic acid. Le into ekhululwa khona futhi ulwelwe abathile banamuhla. Umphumela eyatholakala kusukela photosynthesis nefotosintetiki glycolic acid. Lokhu-ke nomthelela nasekuqiniseni ukusetshenziswa i-oksijini ukuze namachibi compounds.

isiphetho

Glycolic acid - lokhu kungukuqiniseka okuyinto oxidized ukwakha carbon dioxide eyingozi eziningana kwamakhemikhali. Ngakho, kungashiwo waphetha ngokuthi, kwakheka enkulu oksijini komoya glycolic ngaphezulu acid is. Lokhu kunikeza umfutho high ukukhanya ukuphefumula. Ngenxa yalokho, ngo-medium, semali-carbon dioxide. Ososayensi basikisela ukuthi isimiso esifanayo yasekelwa ezitshalweni ikhono ukukhanya ukuphefumula isiqondiso ngokuhambisana ezingeni-carbon dioxide emoyeni. Organisms kungukuthi kuphela ugxile kusukela imvelo umoya-mpilo yingozi photosynthesis eziphilayo, kodwa futhi ukhiqiza isikhutha, okubangela ababewadinga.

ucwaningo

Ungabona practice indlela yokuphefumula isitshalo. 6 lwezifundo eklasini biology ngokuningiliziwe enkulu esikhanyisa lo mbuzo. Ukuqapha inqubo kungathatha ucezu imbali zasendlini. Futhi uzodinga khulu, esitsheni esobala ogcwele amanzi futhi straw cocktail. Eziye zenzeka zibonisa ukuthi izitshalo ukuphefumula, hhayi kuphela ukuqonda inkambo inqubo, kodwa futhi ukuze abone isidingo isampuli umoya-mpilo. On isigaba ishidi ungabona izimbobo ezincane. Ingxenye isampuli emanzini, nge olubilayo uyalandelwa. Kukhona enye indlela esingathola ukuze ubone ukuthi izitshalo ukuphefumula. Ukuze wenze lokhu, thatha ibhodlela, uthele amanzi kulo,, kusale lutho sezinye amasentimitha mayelana emibili kuya kwemithathu. Ishidi esiqwini eside sifakwe ukuze ithiphu yayo egxilile ketshezi. Hole ibhodlela ubumba uvalwe usithe (esikhundleni kukakhokho). Kukhona umgodi ukuze utshani okuyinto ifakwe ukuze akusho zithinta amanzi. Ngokusebenzisa straw kufanele ncela emoyeni kusukela ibhodlela. Kusukela stem, emanzini, Bubbles izonikezwa.
