IMPENDULO: Ewe, uHlanganiso lweSelula luzisa imingeni kunye nezithintelo, ezifana nemfuneko yokuqonda ngokweenkcukacha iindlela zemolekyuli ezibandakanyekayo, kunye nokuba nokwenzeka kokuvelisa iimpendulo ezingafunwayo ze-immunological ngokuzisa amacandelo angaphandle kwiseli.

Umbuzo: Yintoni ukubaluleka kokuDityaniswa kweSelula kwibhayoloji yeeseli kunye namayeza?
A: Ukudityaniswa kweeSewula kubalulekile kwibhayoloji yeselula kunye namayeza, kuba kusivumela ukuba siqonde ngcono iinkqubo zeselula kunye neziphumo zazo kwimpilo nakwizifo. Ukongeza, inokubonelela ngezixhobo ezintsha zonyango zonyango lwezifo kunye nokulimala. .

Iimbono zexesha elizayo

Isishwankathelo, ukuhlanganiswa kweeseli yinkqubo ebalulekileyo yokusebenza kunye nokuphila kwezinto eziphilayo. Ngonxibelelwano kunye nolungelelwaniso phakathi kweeseli ezahlukeneyo, i-homeostasis iyagcinwa kwaye imisebenzi entsonkothileyo iyenziwa. Ukususela ekusebenzisaneni kweeprotheni ze-membrane ukuya ekudlulisweni kwezibonakaliso ze-intracellular, yonke into yokudibanisa kwamaselula igalelo kubudlelwane obuhambelanayo phakathi kweeseli.

Ngokuvela kwenzululwazi kunye nobuchwepheshe, siye sazinzisa ulwazi lwethu malunga neendlela kunye neenkqubo ezenza ukuba ukuhlanganiswa okunjalo kwenzeke. Ukuqhubela phambili kuphando kuchonge iimolekyuli eziphambili, iindlela zokubonisa, kunye nezinto ezilawula unxibelelwano lweselula ziphuhliswa ukunyanga izifo⁢ kunye nokuphucula ⁤impilo yabantu.

Nangona kuninzi okushiyekileyo okuza kufunyaniswa kweli candelo linika umdla, ukudityaniswa kweeseli kuyaqhubeka ukuba yintsika esisiseko yokuqhubela phambili kwebhayoloji kunye nesayensi yezempilo. Ukuqonda indlela iiseli ezinxibelelana ngayo, ukulungelelanisa nokulawula kubalulekile ukuqonda iinkqubo zebhayoloji kunye nokuphuhlisa izicwangciso ezintsha zonyango. Njengoko uphando luqhubeka luqhubela phambili, siya kuqhubeka sityhila iimfihlakalo zokuhlanganiswa kwamaselula kwaye sisebenzise olo lwazi ukuphucula umgangatho wobomi bethu.
