Kev ua haujlwm ntawm Membrane Proteins

Membrane proteins tuaj yeem ua haujlwm ntau yam ntawm tus yuam sij muaj nuj nqi : Junctions – Pab kom txuas thiab koom ob lub hlwb ua ke. Enzymes - Kho rau daim nyias nyias localises cov txheej txheem metabolic. Tsheb thauj mus los - Lub luag haujlwm rau kev yooj yim diffusion thiab nquag thauj

Tsis tas li lo lus nug yog, dab tsi yog qhov sib txawv ntawm cov proteins membrane thiab lawv txoj haujlwm?

Muaj nuj nqi

  • Membrane receptor proteins relay signals ntawm lub cell sab hauv thiab sab nraud ib puag ncig.
  • Thauj cov proteins txav cov molecules thiab ions hla lub membrane.
  • Membrane enzymes yuav muaj ntau yam dej num, xws li oxidoreductase, transferase lossis hydrolase.

Ib tug kuj 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.

Hais txog qhov no, dab tsi yog qhov txawv ntawm daim nyias nyias 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 , ob hom 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

Dab tsi yog 5 hom membrane proteins?

1 Teb

  • thauj cov protein. Cov proteins transmembrane tuaj yeem tsim cov pore lossis channel hauv daim nyias nyias uas yog xaiv rau qee cov molecules.
  • Enzymes. Cov proteins no muaj cov haujlwm enzymatic.
  • Teeb liab transduction proteins.
  • Paub cov proteins.
  • Koom nrog cov protein.
  • Daim ntawv txuas.
