Nws rhuav tshem cov qauv qub thiab tsis tsim nyog kom lawv cov molecules tuaj yeem rov siv dua. Lysosomes yog ib feem ntawm endomembrane system , thiab qee lub hlwv uas tawm hauv Golgi raug khi rau lysosome . Lysosomes tuaj yeem zom cov khoom txawv teb chaws uas tau coj mus rau hauv lub cell los ntawm sab nraud.
Yog li, lysosomes puas yog ib feem ntawm Endomembrane system?
Cov membranes faib cov cell mus rau hauv kev ua haujlwm thiab cov txheej txheem, lossis cov organelles. Hauv eukaryotes cov organelles ntawm lub endomembrane system muaj xws li: cov ntaub so ntswg nuclear, endoplasmic reticulum, Golgi apparatus, cov lysosomes , vesicles, endosomes, thiab plasma (cell) membrane ntawm lwm tus.
Tsis tas li ntawd, vim li cas mitochondria tsis yog ib feem ntawm Endomembrane system? Txawm tias tsis yog technically nyob rau hauv lub cell, plasma membrane yog suav nrog endomembrane system vim, raws li koj yuav pom, nws cuam tshuam nrog lwm cov kab mob endomembranous. Cov endomembrane system ua tsis yog suav nrog cov membranes ntawm ob qho tib si mitochondria los yog chloroplasts.
Ib yam li ib tug yuav nug, dab tsi yog cov khoom ntawm Endomembrane system thiab nws txoj haujlwm yog dab tsi?
Lub endomembrane system muaj xws li lub hnab ntawv nuclear, cov lysosomes , cov hlab ntsha , ER, thiab Golgi apparatus , nrog rau cov plasma membrane. Cov khoom siv ntawm tes no ua haujlwm ua ke los hloov kho, pob, tag, thiab thauj cov proteins thiab lipids uas tsim cov membranes.
Dab tsi yog qhov tseem ceeb ntawm Endomembrane system?
Sorting ntawm cov ntaub ntawv los ntawm Endomembrane System Ntau yam membranes koom nrog, txawm tias muaj kev cuam tshuam, sib txawv hauv cov qauv thiab kev ua haujlwm. Cov endomembrane system plays ib heev tseem ceeb Lub luag haujlwm hauv kev txav cov khoom nyob ib puag ncig ntawm tes, tshwj xeeb tshaj yog cov protein thiab daim nyias nyias (tom kawg yog hu ua membrane trafficking).
Pom zoo:
Endomembrane system ua haujlwm li cas?
Lub endomembrane system yog ib tug series ntawm compartments uas ua hauj lwm ua ke rau pob, daim ntawv lo, thiab nkoj proteins thiab molecules. Hauv koj lub hlwb, endomembrane system yog tsim los ntawm ob qho tib si endoplasmic reticulum thiab Golgi apparatus. Cov ntaub ntawv no yog cov folds ntawm daim nyias nyias uas tsim cov hlab thiab cov hnab hauv koj lub hlwb
Cov organelles twg yog ib feem ntawm Endomembrane system?
Nyob rau hauv eukaryotes cov organelles ntawm lub endomembrane system muaj xws li: lub nuclear membrane, endoplasmic reticulum, Golgi apparatus, lysosomes, vesicles, endosomes, thiab plasma (cell) membrane ntawm lwm tus
Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
Yuav ua li cas koj sau ib feem raws li ib tug khoom ntawm ib tug tag nrho cov zauv thiab ib feem feem?
Cov cai los nrhiav cov khoom ntawm ib feem feem thiab tag nrho tus lej Peb xub sau tag nrho cov lej ua ib feem, piv txwv li, sau nws faib los ntawm ib qho; Piv txwv li: 7 yog sau ua 71. Peb mam li muab cov zauv. Peb muab cov denominators. Yog tias yuav tsum tau ua kom yooj yim, nws ua tiav thiab tom qab ntawd peb sau cov feem kawg
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
