Peripheral membrane proteins yog pom nyob rau sab nraud thiab sab hauv ntawm daim nyias nyias , txuas nrog rau ib qho cov proteins los yog phospholipids.

Ib yam li ntawd, tib neeg nug, dab tsi yog cov proteins pom hauv cell membrane?

Membrane Proteins - Ntog Ntog Koj yuav nrhiav tsheej lab ntawm embedded protein ntau molecules thaum koj saib cov cell membrane . Txhua hom protein ntau muaj lub hom phiaj tshwj xeeb. Piv txwv ntawm membrane proteins suav nrog ion channels, receptor cov proteins , thiab cov proteins uas tso cai hlwb los sib txuas.

Kuj Paub, vim li cas cov proteins muaj nyob hauv cell membranes? Membrane proteins ua ntau yam haujlwm tseem ceeb rau kev ciaj sia ntawm cov kab mob: Membrane tus neeg txais kev pab cov proteins relay teeb liab ntawm lub cell cov sab hauv thiab sab nraud ib puag ncig. Kev thauj mus los cov proteins txav molecules thiab ions hla lub daim nyias nyias . Cell adhesion molecules tso cai hlwb los txheeb xyuas thiab sib tham.

Tsis tas li ntawd, cov proteins nyob qhov twg hauv lub cell?

Ribosomes yog pom nyob rau hauv ntau qhov chaw nyob ib ncig ntawm eukaryotic cell . Tej zaum koj yuav nrhiav Lawv ntab hauv cytosol. Cov floating ribosomes ua cov proteins uas yuav siv tau nyob rau hauv cell . Lwm cov ribosomes yog pom ntawm endoplasmic reticulum.

Dab tsi yog 2 hom proteins pom nyob rau hauv cell membrane?

2 yog cov ntaub ntawv uas muaj nyob rau hauv integral membrane proteins , xws li, transmembrane α-helix protein ntau , transmembrane α-helical protein ntau thiab transmembrane β-daim ntawv protein ntau . Ib qho monotopic cov proteins yog ib hom ntawm integral membrane proteins uas txuas nrog tsuas yog ib sab ntawm lub daim nyias nyias thiab tsis txhob hla tag nrho txoj kev hla.
