I-Metabolism yinkqubo oyisebenzisayo umzimba wakho ukwenza amandla kukutya okutyayo. Ukutya kwenziwa ngeeproteni, ii-carbohydrate kunye namafutha. Iikhemikhali kwinkqubo yakho yokwetyisa (ii-enzymes) ziqhekeza iindawo zokutya zibe ziiswekile neeasidi, amafutha omzimba wakho. Umzimba wakho ungawasebenzisa la mafutha ngoko nangoko, okanye unokugcina amandla kwizicwili zomzimba wakho. Ukuba unengxaki yokuphazamiseka emzimbeni, kukho into ehamba gwenxa ngale nkqubo.

Izifo zeMitochondrial liqela leengxaki zokuphazamiseka komzimba. IMitochondria zizinto ezincinci ezivelisa amandla phantse kuzo zonke iiseli zakho. Benza ngokudibanisa ioksijini neemolekyuli zepetroli (iswekile kunye namafutha) avela kukutya kwakho. Xa i-mitochondria inesiphene, iiseli azinawo amandla aneleyo. Ioksijini engasetyenziswanga kunye neemolekyuli zepetroli ziyakha kwiiseli kwaye zibangele umonakalo.

Iimpawu zesifo se-mitochondrial ziyahluka. Kuxhomekeka ekubeni zingaphi ii-mitochondria ezineziphene, kwaye ziphi emzimbeni. Ngamanye amaxesha kuchaphazela ilungu elinye, izicwili, okanye uhlobo lweseli. Kodwa amaxesha amaninzi ingxaki ichaphazela uninzi lwazo. Imisipha kunye neeseli zemithambo-luvo zineemfuno zamandla ngokukodwa, ke iingxaki zemisipha kunye nemithambo-luvo ziqhelekile. Izifo ziqala ukusuka kubumnene ukuya kubunzima. Ezinye iintlobo zinokubulala.

Ukutshintsha kwemfuza kubangela ezi zifo. Zidla ngokwenzeka ngaphambi kweminyaka engama-20, kwaye ezinye zixhaphake kakhulu kwiintsana. Akukho lunyango kwezi zifo, kodwa unyango lunokunceda ngeempawu kunye nokunciphisa isifo. Banokubandakanya unyango lomzimba, iivithamini kunye nezongezo, izidlo ezikhethekileyo, kunye namayeza.
