Cov ntshav ntshav yog "filling" ntawm lub cell , thiab tuav cov cell cov organelles. Yog li, sab nraud daim nyias nyias ntawm cell yog qee zaum hu ua tus cell membrane thiab qee zaum hu ua tus plasma daim nyias nyias , vim hais tias yog dab tsi nws yog nyob rau hauv kev sib cuag nrog. Yog li ntawd, tag nrho cov hlwb yog surrounded los ntawm ib tug plasma daim nyias nyias.
Hais txog qhov no, leej twg muab lo lus plasma membrane?
Lub sij hawm 'Plasma membrane' tau muab los ntawm Pfeffer. Nws nyob hauv phab ntsa ntawm tes thiab tseem hu ua cell membrane, plasma lemma lossis cytomembrane. Lo lus 'Plasma lemma' tau muab los ntawm Plower (1931). Nageli thiab Cramer (1855) siv lo lus 'Cell membrane'.
Ib yam li ntawd, puas yog cell membrane thiab plasma membrane tib yam? Tsis yog, plasma daim nyias nyias thiab cell membrane tsis yog cov ib yam . Plasma membrane yog cov daim nyias nyias nyob ib puag ncig cov organelles. Ntawm qhov tsis sib xws, cell membrane yog cov daim nyias nyias uas nyob ib puag ncig tag nrho cell.
Ib yam li ntawd, dab tsi yog hu ua plasma membrane?
Cov cell membrane (kuj paub raws li cov plasma daim nyias nyias (PM) lub cytoplasmic membrane , thiab keeb kwm hu ua plasmalemma) yog kev lom neeg daim nyias nyias uas cais cov sab hauv ntawm txhua lub hlwb los ntawm ib puag ncig sab nraud (qhov chaw extracellular) uas tiv thaiv cov cell los ntawm nws ib puag ncig.
Cov plasma membranes nyob qhov twg?
Plasma Membrane ( Cell Membrane ) Cov plasma daim nyias nyias , kuj hu ua cell membrane , yog pom membrane nyob rau hauv tag nrho cov hlwb uas cais cov sab hauv ntawm lub cell los ntawm ib puag ncig sab nraud. Hauv cov kab mob thiab cov nroj tsuag, a cell phab ntsa txuas rau plasma daim nyias nyias ntawm nws sab nrauv.

Vim li cas nws thiaj hu ua Krebs cycle?
Yog vim li cas Nws yog ib lub voj voog Nws yog ib lub voj voog vim oxaloacetic acid (oxaloacetate) yog lub caij nyoog molecule uas yuav tsum tau txais ib qho acetyl-CoA molecule thiab pib dua lwm lub voj voog
Vim li cas nws thiaj li hu ua deoxyribonucleic acid?
Deoxyribonucleic acid (DNA) yog ib qho loj molecule uas muaj nucleotides (phosphate + qab zib + lub hauv paus) qhov twg cov suab thaj yog ' nruab nrab' ntawm nucleotide. Lub 'deoxyribo' hauv lub npe yog muab los ntawm cov piam thaj ntawm DNA. Phosphates thiab qab zib tsim tawm sab nraud ntawm cov molecule thaum lub hauv paus ua rau lub hauv paus
Vim li cas cell membrane tseem hu ua plasma membrane?
Lub plasma yog 'sau' ntawm lub cell, thiab tuav lub cell lub organelles. Yog li, cov txheej txheem sab nraud ntawm lub cell yog qee zaum hu ua cell membrane thiab qee zaum hu ua plasma membrane, vim tias qhov ntawd yog qhov sib cuag nrog. Yog li ntawd, tag nrho cov cell yog surrounded los ntawm ib tug plasma membrane
Dab tsi yog thaj chaw ntawm pej xeem kev hloov pauv thiab vim li cas nws thiaj li muaj txiaj ntsig thaum kawm txog pej xeem?
Population dynamics yog ceg ntawm lub neej sciences uas kawm txog qhov loj thiab hnub nyoog muaj pes tsawg leeg ntawm cov pejxeem raws li dynamical systems, thiab cov txheej txheem lom thiab ib puag ncig tsav lawv (xws li yug thiab tuag tus nqi, thiab los ntawm kev nkag teb chaws thiab emigration)
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
