Membrane cov nqaijrog yuav ua raws li enzymes rau kom tshuaj haum, ua raws li receptors rau tej molecules, los yog thauj ntaub ntawv thoob plaws hauv lub cell daim nyias nyias. Carbohydrates, lossis suab thaj, qee zaum pom muaj txuas nrog cov proteins lossis lipids nyob rau sab nraud ntawm lub cell membrane.
Ib yam li ntawd ib tug yuav nug, dab tsi yog 6 lub luag haujlwm ntawm daim nyias nyias?
Cov ntsiab lus hauv cov teeb no (7)
- 6 Kev Ua Haujlwm ntawm Membrane Proteins. Kev thauj mus los.
- Kev thauj mus los. Hydrophilic channel.
- Enzymatic kev ua haujlwm. Sequential kauj ruam hauv metabolic txoj kev.
- Teeb liab transduction. relay chemical lus.
- Intercellular Joining. Ntau yam Cell Junctions.
- Cell-cell paub.
- Txuas rau cytoskeleton thiab ECM.
Dab tsi yog 3 lub luag haujlwm ntawm plasma membrane? Tshuaj lom neeg daim nyias nyias muaj peb thawj muaj nuj nqi : (1) lawv khaws cov tshuaj lom neeg tawm ntawm lub cell ; (2) lawv muaj cov receptors thiab cov channel uas tso cai rau cov molecules tshwj xeeb, xws li ions, as-ham, pov tseg, thiab cov khoom lag luam metabolic, uas cuam tshuam cov cellular thiab extracellular kev ua ub no kom dhau ntawm organelles thiab nruab nrab ntawm cov khoom.
Tsis tas li ntawd, 4 lub luag haujlwm ntawm membrane proteins yog dab tsi?
Membrane proteins tuaj yeem ua haujlwm ntau yam haujlwm tseem ceeb: Junctions - Pab kom txuas thiab koom nrog ob lub hlwb ua ke. Enzymes - Kho rau daim nyias nyias localises metabolic txoj kev. Thauj - Lub luag haujlwm rau kev yooj yim diffusion thiab nquag thauj.
Dab tsi yog 4 hom membrane proteins?
Raws li lawv cov qauv, muaj peb lub ntsiab hom membrane proteins : thawj tus yog integral daim nyias nyias protein uas yog nyob mus ib txhis anchored los yog ib feem ntawm lub daim nyias nyias , hom thib ob yog peripheral daim nyias nyias protein uas tsuas yog txuas rau ib ntus rau lipid bilayer lossis rau lwm qhov sib xyaw cov proteins , thiab peb

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Lub luag haujlwm ntawm lub cev muaj zog proteins yog dab tsi?
Lub cev muaj zog yog cov molecular motors uas siv ATP hydrolysis txav raws cytoskeletal filaments nyob rau hauv lub cell. Lawv ua tiav ntau lub luag haujlwm hauv cov kab ke lom neeg, suav nrog kev tswj cov zawv zawg ntawm filaments hauv cov leeg nqaij thiab kev sib haum xeeb hauv kev thauj mus los ntawm biopolymer filament lem
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
Lub luag haujlwm ntawm daim nyias nyias thauj proteins yog dab tsi?
Kev thauj cov proteins ua lub qhov rooj rau ntawm tes, pab qee cov molecules hla rov qab mus rau hauv cov plasma membrane, uas nyob ib puag ncig txhua lub cell. Nyob rau hauv passive thauj molecules txav los ntawm ib cheeb tsam ntawm siab concentration mus rau qhov chaw uas tsis muaj concentration
Lub luag haujlwm ntawm transmembrane proteins yog dab tsi?
Ib qho transmembrane protein (TP) yog ib hom kab mob sib xyaw ua ke ntawm cov protein uas nthuav tawm tag nrho cov cell membrane. Ntau cov proteins transmembrane ua haujlwm raws li lub rooj vag tso cai rau kev thauj cov khoom tshwj xeeb hla ntawm daim nyias nyias
