Sonke siyazi ukuba ukutya esikutyayo kunika iiseli zethu amandla eziwadingayo ukuze ziphile kwaye zikhule. Le nkqubo ibizwa ngokuba yi-"metabolism." Kodwa ubusazi na ukuba iiseli zomhlaza zifumana kwaye zisebenzise la mandla ngendlela eyahlukileyo neyobuqili? Enyanisweni, le metabolism ikhethekileyo yeeseli zomhlaza yeyona nto iphambili kwiingcali zesayensi eziphanda ukunqanda umhlaza. Makhe sithethe ngayo namhlanje.
Yintoni umahluko phakathi kweeseli eziqhelekileyo kunye neeseli zomhlaza?
Cinga ngeseli esempilweni emzimbeni wethu njengomntu owenza umsebenzi ofunekayo wosuku kuphela aze atye ukutya okufunekayo kuphela. Ezi seli zisebenzisa iicarbohydrate, amafutha kunye neeproteni ekutyeni esikutyayo ukuvelisa amandla eziwadingayo.
Kodwa iiseli zomhlaza azinjalo. Iiseli zomhlaza zifana neqela lamasela anomdla kwaye anganeliseki. Zitya iglucose eninzi, uhlobo lweswekile, kuneeseli eziphilileyo. Zifunxa le glucose kwaye ziyisebenzisele ukuvelisa amandla kungekuphela nje ukuze ziphile, kodwa kwanokwahlulwahlulwa, ukwanda, nokusasazeka emzimbeni wonke ngesantya esimangalisayo. Enye yezona ngxaki zinkulu kunye neenjongo zonyango namhlanje kukuyeka le nkqubo kwaye kutshabalalise iiseli zomhlaza kuphela ngaphandle kokulimaza iiseli eziphilileyo.
Iindlela ezintsha zonyango ezijolise ekulweni nomhlaza
Xa sicinga ngonyango lomhlaza, i-chemotherapy kunye ne-radiation zifika engqondweni. Ezi zihlala zisebenza ngokutshabalalisa iiseli ezahlukana ngokukhawuleza. Nangona kunjalo, zingonakalisa nezinye iiseli ezisempilweni emzimbeni wethu kunye neeseli zomhlaza.
Kodwa ezi ndlela zonyango zibizwa ngokuba zezo zijoliswe kuzo ziyindlela eyahlukileyo neyanamhlanje.
Ngamafutshane, i-chemotherapy ifana nokuphosa ibhombu kwindawo yemfazwe, ibulale abalungileyo nababi. Unyango olujoliswe ekujoliswe kulo lufana nesixhobo sokudubula, esijolise ngqo size sibethe kuphela apho ingxaki ikhoyo.
Olu nyango aluzibulali ngokuthe ngqo iiseli zomhlaza. Endaweni yoko, luphazamisana nemetabolism edlayo yeeseli zomhlaza. Oko kukuthi, luthintela iiseli zomhlaza ekufumaneni "ukutya" ezikufunayo. Iiseli zomhlaza ezilambayo emva koko azikwazi ukwahlukana okanye ukusasazeka. Ekuhambeni kwexesha, ithumba liyancipha lize life.
Eyona nzuzo inkulu yale ndlela kukuba ichaphazela kakhulu iiseli zomhlaza kuphela, kwaye umonakalo omncinci kwiiseli eziphilileyo. Olu nyango sele lusetyenziswa kumhlaza wesinyi, webele, wemiphunga, wezintso, wesisu, umhlaza wolusu (i-melanoma), kunye nezinye iintlobo ze-leukemia kunye ne-lymphoma.
Luluphi uphando oluqhutywayo kwixesha elizayo?
Izazinzulu ziyaqhubeka nokuphanda ngeendlela ezintsha zokuphazamisa imetabolism yomhlaza. Kodwa uninzi lwazo zisesekwinqanaba lelebhu kunye nezifundo zezilwanyana. Azikakulungeli ukusetyenziswa ngabantu. Kodwa zinethemba elikhulu ngekamva.
Jonga itheyibhile engezantsi ukuze ubone iindawo eziphambili abazijolise kuzo.
| Ithagethi | Indlela enokusetyenzwa ngayo |
|---|---|
| Iswekile | Ekubeni i-glucose iyindawo yokutya ephambili yeeseli zomhlaza, uphando luyaqhubeka ukubona ukuba kunokwenzeka na "ukuzilambisa" iiseli zomhlaza ngokunciphisa amanqanaba e-glucose emzimbeni ngamayeza okanye ukutya. |
| Ii-amino acids | Ezi zezona zinto zisisiseko zokwakha iiproteni. Zikwabalulekile ukuze iiseli zomhlaza zikhule. Ngoko ke, ngokulawula ukufikelela komzimba kwii-amino acids ezifunekayo ngokukodwa kwiiseli zomhlaza, sinokumisa ukukhula komhlaza. |
| Iinkqubo zemiyalezo | Iiseli zomhlaza zineproteni ezikhethekileyo kunye nee-enzymes ngaphakathi kuzo ezizixelela ukuba "zahlukane kwaye zisasazeke ngokukhawuleza." Ngokwenza amayeza athintela ezi nkqubo zokubonisa, iiseli zomhlaza zinokunikwa imiqondiso yokuzitshabalalisa. |
Ngaba ukutya okunokuchaphazela oku?
Lo ngumbuzo abantu abaninzi abanawo. Xa kufikwa kwimetabolism yomhlaza, kukwakho nophando olwenziweyo malunga nokutya. Ngokukodwa, bajonga ukuba izinto ezifana nokuzila ukutya kunye nokutya kwe-keto zinokuchaphazela na iiseli zomhlaza.
Kodwa kukho into ebaluleke kakhulu ekufuneka uyikhumbule apha.Ezi zisesekwinqanaba lophando. Akukho sikhokelo sesayensi esicacileyo okwangoku malunga nendlela yokutshintsha ukutya ukuze kujoliswe kwindlela yokugaya ukutya komhlaza, okanye ukuba kuya kusebenza na kuzo zonke iintlobo zomhlaza.
Ngoko ke, kunokuba yingozi kakhulu kumntu onomhlaza ukwenza utshintsho olukhulu kwindlela atya ngayo ngokusekelwe koko akufunda kwi-intanethi ngaphandle kokuthetha nogqirha wakhe . Ukwenza njalo kunokwenza umzimba ube buthathaka kwaye kunciphise nokukwazi kwawo ukumelana nonyango.
Iingcali zicebisa ukuba izigulane ezinomhlaza zitye ukutya okwahlukeneyo okubonelela ngezondlo zonke, kuquka iivithamini, iiminerali, iiproteni, iicarbohydrate, amafutha kunye namanzi. Ngokukodwa, kubalulekile ukufaka iintlobo ngeentlobo zemifuno, iziqhamo, iinkozo ezipheleleyo, iimbotyi kunye namandongomane ekutyeni, kunye nokunciphisa inyama ebomvu, inyama ecutshungulweyo efana neesoseji, iziselo ezineswekile, kunye nokutya okucutshungulweyo kakhulu.
Umyalezo Wokuya Ekhaya
- Umetabolism yomhlaza yinkqubo ekhethekileyo apho iiseli zomhlaza zifumana amandla okukhula nokusasazeka.
- Iiseli zomhlaza zitya iglucose (iswekile) eninzi kuneeseli eziphilileyo.
- Unyango olujoliswe kulo luyindlela yanamhlanje yonyango ephazamisa inkqubo ye-metabolic yeeseli zomhlaza kwaye iyeke ukukhula kwazo.
- Nangona kukho uphando malunga nolwalamano phakathi kokutya kunye ne-metabolism yomhlaza, akukabikho zikhokelo ziqinileyo ngalo mba.
- Ukuba umntu ofumana unyango lomhlaza wenza naluphi na utshintsho kwindlela atya ngayo, kufuneka akwenze oko kuphela phantsi kwengcebiso kagqirha wakhe .
