Qhov Tseem Ceeb Qhov txawv - Cell Membrane vs Cytoplasm
Lub xovtooj yog lub tsev tsim kev tsim kho ntawm cov kabmob muaj sia. Cell membrane thiab cytoplasm yog ob qho tseem ceeb ntawm lub cell. Lawv txoj haujlwm thiab cov qauv yog qhov tseem ceeb heev rau kev ciaj sia thiab kev loj hlob ntawm cov cell nyob. Lub cell membrane yog ib tug dynamic, ilv, ob-txheej qauv tsim los ntawm lipids thiab proteins. Lub luag haujlwm tseem ceeb ntawm cov cell membrane yog kev tswj hwm kev txav ntawm cov khoom hauv thiab tawm ntawm lub cell. Cytoplasm yog lub semifluid matrix nyob rau hauv lub plasma membrane thiab sab nraum lub nucleus uas tag nrho lwm cov cell organelles yog embedded. Qhov sib txawv tseem ceeb ntawm Cell Membrane thiab Cytoplasm yog, lub cell membrane yog ib qho kev tiv thaiv ib puag ncig uas npog tag nrho cov cell nrog rau cytoplasm thaum lub cytoplasm yog pob tshab jelly-zoo li semi-kua tam sim no nyob rau hauv lub cell membrane thiab nucleus uas nyob rau hauv lub cell. tag nrho cell.
Cell Membrane yog dab tsi?
Cov cell membrane (plasma membrane) txhais tau tias yog ob txheej txheej phospholipid membrane uas cais cov sab hauv ntawm tes los ntawm sab nraud ib puag ncig hauv ob lub hlwb prokaryotic thiab eukaryotic. Singer thiab Nicolson thawj zaug piav txog cov cell membrane qauv nyob rau hauv 1972. Raws li cov kua mosaic qauv piav qhia los ntawm Singer thiab Nicolson, cov phospholipids nyob rau hauv lub plasma membrane yog ua los ntawm hydrophilic phosphate hau thiab hydrophobic fatty acid tails. Cov phospholipids tau teem rau hauv ib txoj kev coj lawv cov tails hydrophobic sab hauv thiab hydrophilic taub hau sab nraud.
Muaj ob txheej phospholipid tam sim no nyob rau hauv lub cell membrane. Nyob rau hauv lub phospholipid bilayer, muaj ntau hom proteins nyob. Peb hom proteins yog ib qho proteins, peripheral proteins thiab transmembrane proteins. Qee cov proteins hla txhua txoj hauv kev los ntawm daim nyias nyias thiab ua haujlwm raws li cov channel lossis cell receptors thaum lwm tus tuaj yeem pom ntawm ntug ntawm cov cell membrane txuas nrog cov carbohydrates (glycoprotein). Cov roj (cholesterol) kuj tseem tuaj yeem pom hauv cov plasma membrane. Cov roj (cholesterol) cuam tshuam qhov fluidity ntawm plasma membrane.
Daim duab 01: Cell Membrane
Lub luag haujlwm tseem ceeb ntawm cov cell membrane yog kev tiv thaiv ntawm tes ntawm nws ib puag ncig. Nws txwv kev sib pauv ntawm cov ntaub ntawv ntawm lub xov tooj ntawm tes thiab nws ib puag ncig (ua raws li ib qho kev xaiv permeable membrane). Qee lub hlwb tau hloov cov plasma membranes. Piv txwv li, cov plasma membranes ntawm nutrient-absorbing hlwb nyob rau hauv cov hnyuv me, daim nyias nyias yog folded rau hauv cov ntiv tes zoo li projections hu ua 'microvilli'. Qhov kev hloov kho no ua rau thaj tsam thaj tsam ntawm cov plasma membrane. Thiab nws kuj ua rau kom cov kev ua tau zoo ntawm cov as-ham absorption.
YCytoplasm yog dab tsi?
Lub cytoplasm txhais tau tias yog jelly-zoo li semifluid matrix nthuav tawm nyob nruab nrab ntawm lub hnab ntawv nuclear thiab cov cell membrane hauv eukaryotes. Tab sis nyob rau hauv cov ntaub ntawv ntawm prokaryotic hlwb, nws yog txhais raws li jelly-zoo li semi-kua uas pom nyob rau hauv lub plasma membrane. Lub cytoplasm muaj jelly zoo li "cytosol" lub npe hu ua ib qho dej ntawm cov cytoplasm. Lub cytosol muaj dej, ions, me me molecules thiab macromolecules. Lub eukaryotic cell kuj muaj cov membrane-bound organelles hauv cytosol.
Daim duab 02: Cytoplasm
Lub cytoskeleton yog ib lub network ntawm fibers uas pom nyob rau hauv lub cytoplasm. Lub cytoskeleton muab cov duab rau lub cell, thiab nws txhawb lub cell thiab. Muaj ntau cov proteins raug tshem tawm hauv cytoplasm. Nws muaj lwm cov molecules xws li qab zib, carbohydrates, lipids thiab ions xws li; sodium, potassium thiab calcium. Feem ntau cov tshuaj metabolic tshwm sim hauv cytoplasm. Nws ua haujlwm raws li kev tshaj tawm xov xwm.
Dab tsi zoo sib xws ntawm Cell Membrane thiab Cytoplasm?
- Ob leeg yog cov khoom ntawm ib lub xovtooj.
- ob leeg yog lub luag haujlwm muab lub cev rau lub cell.
- Ob leeg tseem ceeb heev rau kev ciaj sia ntawm tes.
- Proteins, lipids, carbohydrates tuaj yeem pom hauv ob lub cell membrane thiab cytoplasm.

Summary – Cell Membrane vs Cytoplasm
Lub xovtooj ntawm tes yog lub hauv paus ntawm biology. Thiab nws tau tshawb pom los ntawm tus kws tshawb fawb Askiv Robert Hooke hauv xyoo 1665. Lub xovtooj ntawm tes muaj cov khoom tseem ceeb xws li cell membrane, cytoplasm, cell organelles thiab nucleus khaws cia nrog cov khoom siv caj ces. Lub cell membrane yog daim ntawv tiv thaiv uas npog tag nrho cov cell. Lub cytoplasm thiab nucleus ua ke ua ib feem ntawm lub cell hu ua protoplasm. Cytoplasm yog suav tias yog jelly-zoo li semi-kua uas tshwm sim nyob rau hauv nruab nrab ntawm lub hnab ntawv nuclear thiab cell membrane hauv eukaryotes. Tab sis nyob rau hauv cov ntaub ntawv ntawm prokaryotic hlwb, nws yog cov jelly-zoo li semi-kua pom nyob rau hauv lub plasma membrane. Lub cytoplasm muab cov tshuaj tiv thaiv kab mob rau cov hlwb cov tshuaj tiv thaiv metabolic. Lub cytoplasm tseem tuav ntau lub cell organelles. Qhov no yog qhov txawv ntawm cell membrane thiab cytoplasm.
