A membrane m

Allaha membrane m ne lantarki m (da stock), wanda aka kafa tsakanin matsanancin surface na jikin tantanin da kuma na ciki gefen na jini membrane. A ciki gefen membrane dangi zuwa da matsanancin surface ko da yaushe yana yin mummunan cajin. Domin kowane irin cell Allaha m ne ma m girma. Saboda haka, a dumin jiki a cikin zaruruwa na kwarangwal tsoka shi ne 90 mv, cell infarction - 80, na jijiya Kwayoyin - 60-70. A membrane m ne ba a duk rayayyun tantani.

A daidai da zamani ka'idar dauke wutar lantarki, wadata da aka kafa a sakamakon aiki da kuma m motsi ions.

M motsi faruwa tare da maida hankali dan tudu ba ya bukatar makamashi da shigar da ita. Cell membrane a shimfida matsayi ne ya fi permeability zuwa potassium ions. A cytoplasm na jijiya da tsoka Kwayoyin su (potassium ions) ba a cikin talatin zuwa hamsin sau fi a intercellular ruwa. A cytoplasm ions ne a free tsari da kuma diffused bisa ga maida hankali dan tudu, a cikin extracellular ruwa a fadin membrane. A interstitial ruwa kwayuka anions ana kiyaye shi a kan m surface na membrane.

A cikin kwayuka sarari ya ƙunshi, yafi anions pyruvic, acetic, aspartic acid da sauran Organic acid. A inorganic acid da aka dauke a cikin wani gwada da kananan adadin. Anions Alhlulbaiti ta cikin membrane iya ba. Su zauna a cikin keji. Anions aka shirya a ciki gefen membrane.

Saboda gaskiya cewa korau lura da anions da cations a - a, da matsanancin surface na membrane yana da wani m cajin, da kuma ciki - babu.

A extracellular ruwa sodium ions a takwas zuwa goma sau fiye da a cikin wani keji. Su permeability ne low. Duk da haka, saboda shigar azzakari cikin farji na sodium ions wasu har rage membrane m. Lokacin da wannan ya auku da yadawa na chlorine ions a cikin cell. Da abun ciki na wadannan ions a cikin goma sha biyar zuwa talatin har fiye da sau a extracellular ruwaye. membrane m ƙaruwa dan kadan saboda su shigar azzakari cikin farji. Bugu da kari, akwai wata matattarar da musamman kwayoyin inji. Yana bayar da aiki gabatarwa na potassium da sodium ions a cikin shugabanci na ƙara natsuwa. Kamar wancan shi goyon ionic jeri na bangaren.

The aiki motsi ions ne a sakamakon aiki na sodium-potassium "famfo" (famfo). Active hijirar na sodium ions, saboda shigar azzakari cikin farji daga cikin sel a cikin cell a potassium ion. A dual famfo manyan motoci dauke vector wanda, bi da bi, ɗauke da lalata na na rayuwa da makamashi na ATP. Ta hanyar samar da makamashi kwayoyin ATP hydrolysis 2 potassium ion ga shiga cikin sel, da kuma 3 sodium ions hawa fita.

A sauran, da tsoka zaruruwa domin tabbatar da aiki na ion farashinsa da aka kashe har zuwa ashirin bisa dari na salula makamashi.

Ƙarƙashin rinjayar ATPase enzyme cleaves ATP. Guba na jijiya zaruruwa cyanide monoyodatsetatom, dinitrophenol, da kuma sauran abubuwa, ciki har da kawo karshen aiwatar da glycolysis da kuma kira na ATP, shi tsokani (ATP), wani karu a cytoplasm da lõkacin fatara daga aiki na "famfo".

A membrane kuma shi ne permeable zuwa chloride ions (musamman tsoka zaruruwa). A Kwayoyin tare da m permeability, potassium ions da chlorine daidai samar da wata matattarar a sauran. Kamar haka a sauran taimako na karshe cell a ce tsari ne negligible.
