Cov Cell Membrane . Tag nrho cov nyob hauv hlwb thiab ntau ntawm cov me me organelles nyob rau hauv lub hlwb yog bounded los ntawm nyias daim nyias nyias . Cov no daim nyias nyias yog tsim Feem ntau ntawm phospholipids thiab cov proteins thiab feem ntau piav raws li phospholipid bi-layers.
Yog li ntawd, cytoplasmic membrane yog dab tsi?
Cov cell membrane (tseem hu ua 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.
Kuj Paub, dab tsi lwm yam molecules muaj nyob rau hauv lub cell membrane? Cov cell membrane qauv yog cov kua dej mosaic ua los ntawm peb hom organic molecules : lipids, proteins thiab carbohydrates. Cov cell membrane tswj kev txav ntawm cov khoom xws li cov as-ham thiab pov tseg thoob plaws hauv lub daim nyias nyias , nyob rau hauv thiab tawm ntawm lub cell.
Qhov thib ob, kev ua haujlwm ntawm cytoplasmic membrane yog dab tsi?
Cov ntshav ntshav membrane, tseem hu ua cytoplasmic membrane, yog qhov dynamic tshaj plaws qauv ntawm procaryotic cell. Nws lub luag haujlwm tseem ceeb yog ib qho kev xaiv permeability barrier uas tswj cov kev nkag mus ntawm cov khoom mus rau hauv thiab tawm ntawm lub cell.
Cov kab mob puas muaj cov plasma membrane?
Yog lawm. Feem ntau kab mob (prokaryotes) kuj muaj cell phab ntsa sab nraum lub plasma daim nyias nyias nrog rau kev zam ntawm qee pawg ntawm kab mob , tshwj xeeb tshaj yog cov pab pawg Mycoplasma. Lub cell membrane yog ib txheej bi-lipid zoo li cov eukaryotes. Ntau cov poov xab (eukaryotes) muaj cell phab ntsa ib yam nkaus thiab zoo li stain Gram Positive.

Dab tsi yog qhov txawv ntawm cov lus teb cytoplasmic thiab cov lus teb nuclear?
Dab tsi yog qhov txawv ntawm cov lus teb nuclear thiab cov lus teb cytoplasmic? Cov lus teb nuclear cuam tshuam nrog kev hloov pauv ntawm cov noob qhia, thaum cov lus teb cytoplasmic cuam tshuam nrog kev ua kom muaj enzyme lossis qhib ntawm ion channel
Dab tsi yog cytoplasmic inheritance thiab piv txwv?
Qhov qub txeeg qub teg ntawm cov cim tswj los ntawm cov noob muaj nyob rau hauv lub cell cytoplasm es tsis yog los ntawm cov noob ntawm chromosomes nyob rau hauv lub cell nucleus. Ib qho piv txwv ntawm cytoplasmic qub txeeg qub tes yog tswj los ntawm mitochondrial noob (saib mitochondrion)
Lub luag haujlwm ntawm lub cell membrane yog dab tsi thaum lub sijhawm thauj mus los?
Lub cell membrane yog xaiv permeable rau ions thiab organic molecules thiab tswj kev txav ntawm cov khoom hauv thiab tawm ntawm lub hlwb. Lub luag haujlwm tseem ceeb ntawm cov cell membrane yog los tiv thaiv lub cell ntawm nws ib puag ncig. Nws muaj phospholipid bilayer nrog embedded proteins
Dab tsi yog tsib lub hauv paus Circuit Court Cheebtsam lawv lub tsev yog dab tsi?
Cov no yog cov feem ntau siv: resistors. Capacitors. LEDs. Transistors. Inductors. Integrated Circuits
Lub luag haujlwm ntawm cytoplasmic membrane yog dab tsi?
Lub plasma membrane, tseem hu ua cytoplasmic membrane, yog cov qauv zoo tshaj plaws ntawm cov cell procaryotic. Nws lub luag haujlwm tseem ceeb yog ib qho kev xaiv permeability barrier uas tswj cov kev nkag mus ntawm cov khoom mus rau hauv thiab tawm ntawm lub cell
