Carbon Cycle. Imigaqo kunye nokubaluleka

Xa umhlaba onokuphila ngayo umhlaba wethu kukho ezininzi iinkqubo ezintsonkothileyo zibangelwa umsebenzi ebalulekileyo eziphilayo, impembelelo utshintsho zabantu yokuzivelela ezenzeka, ndineemfesane Ebubanzini kunye ezinzulwini kolwandle. Umntu engundoqo umjikelo carbon. Ngaphandle kwalo, ubomi on Earth.

Ubukhulu becala, lokuhamba carbon yindlela jikelele onoxanduva amanani kunye zinomgutyulo emoyeni le carbon dioxide. Nokwenziwa le carbon sonke siyazi photosynthesis, kwaye luxanduva kolu kwisityalo. Khetha / ukubuya carbon dioxide kwenzeka ngokusebenzisa izinto zakhe eziphilayo ngumphunga, umsebenzi kwamashishini zoshishino kunye neenkqubo ibole

Icebo umjikelo carbon uya kumela ngokupheleleyo le nkqubo iquka izigaba ezibini:

• Le nokwenziwa yeKharbon dayokhsayidi (CO ₂₎ izityalo, izinto eziphilayo esasinokubonwa nokuguqulwa kwayo okwalandela zibe ngakumbi iikhompawundi ezingundoqo chemical (amafutha, iikhabhohayidrethi, iiprotheni).
• Ukubuyiswa carbon dioxide emoyeni ngenxa nokuphefumla izidalwa eziphilayo, kunye nangezinye iindlela.

Noko ke, umjikelo carbon inqubo nzima ngakumbi. Ngoko ke, emva kokufa eziphilayo, abanye babo zilungiswa ziibhaktheriya aze okunene wabuyela emoyeni kwixesha elifutshane ixesha. Kodwa inxenye iintsalela iguqulelwa umcimbi efile organic.

Yeyona iintsalela mba eziphilayo kwiminyaka elikhulu embalwa ziya kuguqulelwa, yaye ekugqibeleni ijike ibe amalahle, i-oyile kunye nja-. Ezi minerals zisetyenziselwa iinjongo ezahlukeneyo yoluntu carbon kubo ziya kubuyiselwa kwi-atmosfera.

Ngokwahlukeneyo ufuna ukuhlala kwi inkqubo CO ₂ ukuchacha kumjikelo carbon.

Amafutha. Lipolysis of imvelaphi ezahlukeneyo kunokwenzeka ngenxa inxaxheba kwinkqubo le Cya ukuba enzyme cleavage kwe le ezimbaxa. Oku kukhokelela glycerol kunye fatty ephakamileyo series. Glycerol abole abe pyruvic acid (PVK). Ngoko ke, kuxhomekeke kwiimeko, iba zizikhumba, acid okanye utywala kunye carbon molecule emoyeni izaku phawulwa.

Carbohydrate. Ezi zinto ke abathwali ezingundoqo ifayibha leyo ezifunyenwe kwaye kuphela amagciwane ezithile. Ekuhambeni processing kwakhiwa glucose wayo, nto leyo oxidized phantse zonke iintlobo nomngundo neentsholongwane. Ngenxa yoko, iswekile liyacandeka zizikhumba kunye carbon dioxide. Le - hayi kuphela ukhetho. Inkqubo igcwala inokukhokelela ukuyilwa methane, kodwa ukukhulula carbon esibophelelayo.

Ngenxa yokuba zonke iinkqubo azikho twatse ngokwemiqathango flow yayo, iindidi ezimbini Ukubolekisa zizinto umhlaba onokuphila:

• Yokwakheka komhlaba (ukubunjwa izimbiwa) - ingaqalisa zibe amawaka kunye kwizigidi zeminyaka.
• Eziphilayo (ukufa kunye nokucazululwa kuka izityalo kunye nezilwanyana) - inkqubo esebenzayo kakhulu ezinokuthatha naphi na ukusuka kwiintsuku ezimbalwa ukuya kwiminyaka emininzi.

Kakade ke, inkcazelo thaca apha phezulu kakhulu yaye ayibonisi undoqo inkqubo yemichiza nezinye ngawo ihlabathi kuxhaswa yi kumjikelo carbon.
