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.
