Cov cell membrane Nws yog ib qho lipid bilayer uas tiv thaiv qhov kev nkag ntawm dej thiab ions. Qhov no tso cai hlwb rau tswj ib tug ntau dua concentration ntawm sodium ions tawm sab nraum lub cell . Cells kuj tswj ib tug ntau dua concentration ntawm potassium ions thiab organic acids ntawm lawv sab hauv.
Ua li no, vim li cas cov hlwb yuav tsum muaj kev ruaj ntseg sab hauv?
Cov hlwb uas tsim cov kab mob muaj ib txoj hauj lwm loj - ua kom cov kab mob no noj qab nyob zoo kom lawv loj hlob thiab rov tsim dua. Kev saib xyuas ntawm ruaj khov , tas li , cov xwm txheej sab hauv hu ua homeostasis. Koj cell ua qhov no los ntawm regulating lawv sab hauv ib puag ncig kom lawv txawv ntawm ib puag ncig sab nraud.
Qhov thib ob, yuav ua li cas cov cell membrane tswj kev ruaj khov nyob rau hauv cov xwm txheej ntawm kev txav mus los? Passive Kev thauj mus los Homeostasis nyob ntawm kev tswj xyuas cov kua dej kom raug nyob rau hauv cell thiab ntawm kev sib pauv cov ntaub ntawv siv tau, xws li oxygen, rau cov khoom pov tseg, xws li carbon dioxide. Plasma membranes cia dej, oxygen thiab carbon dioxide hla dhau los ntawm osmosis, los yog passive nthuav tawm.
Kuj kom paub, cov hlwb ua li cas thiaj li tswj tau qhov chaw nyob ruaj khov?
Tej yam muaj sia Ua kom ruaj khov sab hauv Cov xwm txheej Thaum koj sov dhau, koj tawm hws kom tso cua sov. Thaum ib yam kabmob muaj sia raug pov tseg, nws lub cev lossis hlwb pab nws rov zoo li qub. Kev tuav pov hwm kev sib npaug hauv lub cev los yog hlwb ntawm cov kab mob hu ua homeostasis.
Yuav ua li cas lub cell membrane tswj kev sib npaug?
Cov dej xav kom ntws los ntawm cov concentration siab dua, uas yog sab nraud cell , mus rau qis concentration, uas yog nyob rau hauv lub cell . Cov cell membrane pab tswj thiab ua kom qeeb ntawm cov dej ntws mus rau hauv lub cell . Qhov no tseem yog lwm txoj kev uas tus cell membrane pab tswj homeostasis.

Yuav ua li cas anti nodes tsim nyob rau hauv ib tug nyob ruaj ruaj nthwv dej?
Cov nodes thiab antinodes nyob rau hauv ib tug sawv yoj qauv (zoo li tag nrho cov ntsiab lus nyob rau hauv nruab nrab) yog tsim los ntawm kev cuam tshuam ntawm ob nthwv dej. Cov nodes yog tsim nyob rau hauv qhov chaw uas muaj kev cuam tshuam kev puas tsuaj tshwm sim. Antinodes, ntawm qhov tod tes, yog tsim nyob rau hauv qhov chaw uas muaj kev cuam tshuam tshwm sim
Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Yuav ua li cas cov particles nyob rau hauv ib tug ruaj khov txav?
Cov khoom nyob rau hauv ib qho khoom yog nruj nreem ntim thiab kaw rau hauv qhov chaw. Txawm hais tias peb tsis tuaj yeem pom lossis hnov nws, cov particles txav = vibrating nyob rau hauv qhov chaw. Cov kab hauv cov kua yog nyob ze ua ke (kov) tab sis lawv muaj peev xwm txav tau / swb / ntws dhau ib leeg
Yuav ua li cas cov protein nyob sab nraud ntawm tes ua rau muaj xwm txheej tshwm sim hauv lub cell?
Cov protein tuaj yeem dhau los ntawm daim nyias nyias thiab mus rau hauv lub cell, ua rau muaj teeb meem hauv lub cell. b. Ib qho protein nyob sab nraud ntawm tes tuaj yeem khi rau ib qho receptor protein ntawm lub xov tooj ntawm tes, ua rau nws hloov pauv thiab xa cov teeb liab hauv lub cell. Phosphorylation hloov cov duab ntawm cov protein, feem ntau ua rau nws
Dab tsi yog qhov chaw nyob ruaj khov nyob rau hauv nyias txheej chromatography?
Lub silica gel (los yog alumina) yog qhov chaw nres tsheb. Cov theem nyob ruaj khov rau nyias txheej txheej chromatography kuj feem ntau muaj cov khoom siv fluorescesin UV teeb - vim li cas koj yuav pom tom qab. Lub mobilephase yog cov kuab tshuaj uas tsim nyog los yog sib tov ntawm cov kuab tshuaj
