Yintoni catabolism? Iinkqubo izigaba catabolism

umzimba wethu yinkqubo emangalisayo uyakwazi ukugcina uqhagamshelwano esitalini bume. Oku kufezwa ukutya okanye njengoko kubhaliwe ngokuba, ukutya. Nethe ngokwayo yahlulwe kabini: catabolism (amandla ukutya) kunye anabolism (ukutya iplastiki). Abantu abaninzi xanisa la magama. Kodwa bohluke kuzo ngokupheleleyo. Makhe sibone ukuba yintoni catabolism.

Iiyantlukwano catabolism evela anabolism

Ezi nkqubo malunga ngokwendalo. Anabolism - inkqubo yokuqaphela ngxuba zingangeni elula. Kwaye yintoni ke catabolism? Le nkqubo umva. Umzekelo lingamiselwa anabolism of mass kwezihlunu. Kwaye umzekelo kuba catabolism njengoko kunokubangela inani reactions ebalulekileyo omzimba womntu.

Ngokomzekelo, abantu abaninzi abathanda iitapile, akunjalo? Esinye izinto ezisisiseko kuso, ekudaleni incasa oluvuyisayo, istatshi. Le nto a polysaccharide. Oku kuthetha ukuba sinzima kunene ekudleni indalo. Ngako oko ke, iquka nobuninzi ezinye iikhabhohayidrethi, kwaye ibolile zibe iikhompawundi ezintsonkothileyo kangako. Ekupheleni Istatshi ibolile ngumzimba ukuze glucose. It is catabolism.

catabolism alcohol

Umzekelo yesibini yokubola catabolism utywala acetic acid. Le nkqubo oluqhutywa amanyathelo amabini usebenzisa enzyme ezimbini. Okokuqala - oko dehydrogenase utywala. Le enzyme inoxanduva catabolism-ethanol ukuya acetaldehyde. Le into yityhefu, ngoko ke asikwazi ihlale ixesha elide emzimbeni. Ukuba unobangela ibhabhalaza. Kodwa ayikho ingongoma.

Inqanaba lesibini catabolism of ethyl utywala - i cleavage yi enzyme acetaldehyde dehydrogenase acetaldehyde ukuya acetic acid leyo esiswini saso emzimbeni. Kukho nezinye imizekelo eziliqela catabolism. Umzekelo, amafutha kungenziwa lwanamathela glycerol uyadinga acid, iiprotheni kunye - ukuba acid asidi. Kuba bodybuilders uhlobo yokugqibela catabolism kakhulu mnandi, njengoko engaphenduli bafumane ubunzima kwezihlunu.

catabolism Science

Catabolism senzelwe ukuba umzimba amandla. Eneneni, nayiphi na into adluliselwa liqumrhu, i ngumthombo ATP - triphosphate adenosine. Le molecule ezizodwa ezilungiselelwe ukugcinwa, oko kukuthi, ukuqokelelela amandla emzimbeni. Isixa-mali into ke kuyanelisa. Ngoko ke, kufuneka ukuba rhoqo kwakhona. Kwaye oku kungenziwa ngendlela enye kuphela - encediswa catabolism. Le nkqubo ithatha kuqhubeka ngokwezigaba eziliqela. Makhe sihlolisise zonke izigaba catabolism.

Inqanaba lokuqala

Inyathelo lokuqala catabolism - livela cleavage kwezinto ukutya enzyme ezikhethekileyo. Kwezinye izinto, indima enzyme unako ukwenza iihomoni. Umzekelo, iswekile lusicande insulin eveliswe pancreas. Ngoko owanikwa isigaba kuphela exotherm isici. Ayizi zinyamalale ngaphandle, azafunyanelwa ndawo.

Ngokukodwa, oko Isetyenziswa ukulondoloza ubomi obuqhelekileyo yenqanaba eziphilayo. Yaye siziva le nkqubo ekulondolozweni lobushushu emzimbeni ethile. Ngaphezu koko, le isangqa kakhulu umdla. Emva catabolism mazenziwe kuphela xa kukho ubushushu ethile. Ubushushu oluphenthwe Kungokwemvelo ukuba zonke iinkqubo kwemichiza emzimbeni okanye kokusingqongileyo. Inkqubo ukuqhekeka kwezinto ezibalulekileyo unzima kakhulu, ngoko akukho isigaba sesibini buyafuneka.

umlenze yesibini

Inqanaba lesibini kuthiwa glycolysis. Kweli nqanaba, xa ukhula cleavage glucose. Le nkqubo yenziwa esiseleni kukho icytoplasm. Ngenxa kwesigaba sesibini, 40% igcinwe njengoko ATP, kunye nentshiyekela amandla onesiphumo isetyenziswa bubushushu. Ngokubanzi, thermoregulation emzimbeni, njengoko sibona, iindleko kunzima. Kakhulu ngaphezu kwesiqingatha se-eneji iyonke eziveliswa ichithwe nje ukugcina ubushushu umzimba eqhelekileyo. Eli nqanaba lwenzeka ngaphandle inxaxheba oksijini.

Isigaba sesithathu - oksijini

Eli nqanaba catabolism ithatha indawo inxaxheba ngqo kwe-oksijini. Yena ke wazithatha kule mitochondria, ezo nezihlanganisi zethu zendalo. La masuntsu omzimba wethu mancinane kakhulu, abanako kungabonwa ngeliso lenyama. Kulo mzekelo, ezi iibhetri ziyafumaneka kwiseli nganye, ekwaziyo ukutya. Kwaye ke kukho beqokelela ATP. Kwaye ke Isigaba sesithathu sibethelelwe ngokupheleleyo ukuya Yindibanisela triphosphate adenosine.

ngendlela efanayo catabolism

ukuze jikelele nge catabolism kubizwa iseti iinkqubo ezifana:

• Igcwala of pyruvate ukuba acetyl-awula. Le nkqubo ithatha indawo phantsi kwempembelelo enzyme, oyinxalenye isethi igama umdla "pyruvate dehydrogenase ezintsonkothileyo." Kodwa ezi iinkcukacha awabalulekanga ngenene le ndoda eqhelekileyo.
• Elilandelayo igcwala of acetyl-awula. Lisuka ekuthiwa umjikelo citric acid. Kwakhona ngokuba umjikelo Krebs. Le nkqubo liqhosha elungiselelwe nokuphefumla zeselula. Asingawo onke, Kakade ke, kodwa kuphela ezo ezisebenzisa oksijini. Ngawo umjikelo Krebs kamva kwasekwa inkqubo ukwakha anabolism (amagama) ATP, nto leyo umthombo enkulu wamandla kwiseli.
• Emva kwale amandla ekhululwe, kukho ukuqokelela wayo (abekwe). Oku kungenxa metabolites dehydrogenation, eziye zaphumela kuzo kwixesha neenkqubo zangaphambili ezimbini catabolism. dehydrogenation ezingeyomfuneko kwenzeka kwikhonkco yothutho electron ayo.

Ezi iinkqubo catabolism zibaluleke kakhulu ukuze abantu. Ngaphandle kwazo bekuya kuba nzima ukuba khona, kususela catabolism ATP kwiwebhsayithi amandla, nto leyo ke isetyenziswe njengeyeza jikelele kwelifunekayo imizimba yethu.

acid acid catabolism

Ewe, iiprotheni yonakele emzimbeni ibe acid. Kodwa hayi kuphela kwenzeka emzimbeni wethu. Phakathi kwezinye izinto, le acid nazo babandakanyeke ngqo kwi catabolism. Le nkqubo ngokwayo entsonkothileyo kakhulu, ngoko uya inkcazelo esisiseko kuphela, nto leyo nzima ngokwaneleyo ukuba abafundi. It acid yindlela zaseprayimari apho iiproteni zakhiwa.

Akukho ilungu lomzimba, zazingathandanga ukuba iiprothini. Noko ke, abanye babo kunokuba yingozi. Izifo ezifumaneka ngenxa imbonakalo kwiiproteni ezingaqhelekanga lomzimba ekuthiwa prions. Kwaye, umdla ngokwaneleyo, ukuba abanjiswe ngephanyazo.

iziphumo

Saqonda ukuba eli catabolism kwaye yintoni na ukuba imizimba yethu. Isizathu Ilula kakhulu. Nkqu izinto ezininzi eziyimfuneko emzimbeni wethu wambi ezingasafunekiyo. Ngelo xesha ke asikwazi ukwenza ngaphandle kwezi izinto. Catabolism amandla nje kuphela, kodwa ukuze kupheliswe kwakuwo oko kuyimfuneko ukuze imizimba yethu. into nje kakhulu - yinto embi. Kwaye oku kufanele kuqwalaselwe.

Kubalulekile ukuqonda oko catabolism wemfundo ngokubanzi nje kuphela kodwa, umzekelo, ukutshisa umzimba. Kodwa kufuneka silumke kakhulu, ngenxa yokuba ukongeza catabolism amanqatha nga zinokutshisa nobunzima kwezihlunu. Yena akanandaba uwe phantsi kwenkululeko.
