| IBhayibheli lifundisa ukuthi uNkulunkulu wadala zonke izidalwa eziphilayo ngokwezinhlobo. Singaqiniseka ukuthi uNkulunkulu unike izidalwa eziphilayo amakhono namandla adingekayo ukuze ziphile. Masibheke ibhere elimnyama ngalokhu engqondweni.
Ngesikhathi esijwayelekile sokuzizigcina ebusika, izinqubo eziningi zomzimba zehla kakhulu ebhoyeni elimnyama, elingadli noma liphuze ngalesi sikhathi, kodwa lisebenzisa amafutha njengomthombo oyinhloko wamandla. Ukuncipha komsebenzi wemisipha nokulamba okude ngesikhathi sokuzizigcina ebusika kufanele kubangele ukuncipha okukhulu kwemisipha nokulahlekelwa kwamandla.
Ngokumangalisayo, akukho ukulahleka okukhulu kwemisipha emzimbeni webhere ngesikhathi sokulala ebusika, ngaphandle kwamabhere abesifazane abancelisa, abahlangabezana nokulahleka okuncane okuphakathi kuka-4–10% kweprotein yemisipha. |

Kuyavela ukuthi ezingeni lomolekyuli, inani lezifanekiso ezithile ezibhalela ama-enzyme asetshenziselwa ukwakhiwa kweprotein emisipheni yamathambo nasemithanjeni yesibindi zivezwa ngokweqile kakhulu ngesikhathi sokuzindla. Kukhona ukwehliswa ngasikhathi sinye kokubalwa kwamagene akhuthaza ukubhujiswa kweprotein, kanti ukubhujiswa kwezinye izinhlobo ze-collagen type-I ezicubeni zokuxhumana kunikeza ama-amino acid abalulekile ekwakhiweni kweprotein. Lokhu kuvumela amabhere amnyama ukuthi anciphise ukuncipha kwemisipha phakathi nezikhathi ezide zokunganyakazi nokulamba ngesikhathi sokuzindla, okuwavumela ukuthi aphume ekuzindleni entwasahlobo eqinile futhi enamandla, elungele ukuqhubeka nemisebenzi yawo evamile.
Iqiniso elilula nelimangalisayo wukuthi le nqubo yenzeka ngokuzenzakalelayo, ngaphandle kokuthi ibhere emnyama kudingeke icabange ngayo. Ngokwengqondo, uhlelo lwezinto eziphilayo oluyinkimbinkimbi kangaka, oluphelele futhi oluzilawulayo, alunakwenzeka ukuthi lwathuthuka ngokuhamba kwesikhathi noma ngokungahleliwe.
