Hauv biology, matrix (ntau tshaj: matrices ) yog cov khoom (los yog cov ntaub so ntswg) nyob rau hauv tsiaj los yog cog l qauv ntawm connective cov ntaub so ntswg yog ib tug extracellular matrix . Nws muaj nyob rau hauv ntau yam ntaub so ntswg. Nws feem ntau yog siv ua jelly zoo li cov qauv hloov pauv ntawm cytoplasm hauv cov ntaub so ntswg sib txuas.
Ntxiv mus, dab tsi yog matrix tsim los ntawm?
Lub extracellular matrix yog tsim los ntawm proteoglycans, dej, zaub mov, thiab cov protein ntau. Ib tug proteoglycan yog muaj li ntawm cov tub ntxhais protein nyob ib puag ncig los ntawm cov saw ntev ntawm cov hmoov txhuv nplej siab zoo li glycosaminoglycans.
Tom qab ntawd, lo lus nug yog, dab tsi yog matrix hauv keeb kwm? Cov 'av hauv av' ntawm extracellular matrix yog amorphous gelatinous khoom. Nws yog pob tshab, tsis muaj xim, thiab ua kom pom qhov chaw nruab nrab ntawm cov fibers thiab cov cell. Nws yeej muaj cov molecules loj hu ua glycosoaminoglycans (GAGs) uas txuas ua ke los tsim cov molecules loj dua hu ua proteoglycans.
Hais txog qhov no, dab tsi yog qhov matrix ntawm cell?
Hauv biology, matrix (ntau tshaj: matrices ) yog cov khoom (lossis nqaij) hauv tsiaj lossis nroj tsuag hlwb , nyob rau hauv uas cov txheej txheem tshwj xeeb tau kos, thiab ib feem tshwj xeeb ntawm mitochondrion uas yog qhov chaw ntawm oxidation ntawm cov organic molecules.
Lub matrix ua li cas?
Matrix yog cov khoom zoo li gel hauv mitochondrion, lossis organelle uas ua cov txheej txheem ntawm aerobic ua pa , uas muaj ribosomes zoo ib yam li cov kab mob. Nws muaj cov mitochondrion's DNA, uas zoo ib yam li cov kab mob.

Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov pob txha extracellular matrix yog dab tsi?
Cov txheej txheem sab nrauv, uas yog ua los ntawm cov organic matrix (30%) muaj cov proteoglycans (tab sis tsawg dua pob txha mos), glycosaminoglycans, glycoproteins, osteonectin (thauj cov pob txha pob txha mus rau collagen) thiab osteocalcin (calcium khi protein). Muaj collagen fibers (feem ntau yog hom I (90%), nrog qee hom V)
Dab tsi yog kev kho hniav matrix band?
Lub matrix txhais tau hais tias yog ib qho zooA matrix txhais tau tias yog ib qho zoo contoured piece ntawm hlau los yog lwm yam contoured piece ntawm hlau los yog lwm yam khoom siv los txhawb thiab muab daim ntawv tomaterial siv los txhawb thiab muab daim ntawv rau lub restoration thaum nws muab tso rau thiab lub restoration thaum lub sij hawm nws tso thiab tawv. tawv
Dab tsi yog matrix ntawm cofactors?
Tus cofactor yog tus lej koj tau txais thaum koj tshem cov kab thiab kab ntawm cov khoom tsim hauv matrix, uas tsuas yog ib daim phiaj tus lej nyob rau hauv daim duab plaub lossis square
Dab tsi yog qhov me me ntawm 2x2 matrix?
Ib 'me' yog tus txiav txim siab ntawm cov square matrix tsim los ntawm kev rho tawm ib kab thiab ib kab los ntawm qee qhov loj square matrix. Txij li muaj ntau kab thiab kab nyob hauv thawj daim ntawv, koj tuaj yeem ua ntau yam me me los ntawm nws. Cov menyuam yaus no tau sau npe raws li kab thiab kab uas koj tau muab tshem tawm
Dab tsi yog cov ntaub so ntswg matrix?
Cov ntaub so ntswg sib txuas yog tsim los ntawm cov matrix uas muaj cov cell muaj sia thiab cov khoom tsis muaj sia, hu ua cov khoom hauv av. Cov av hauv av yog ua los ntawm cov organic (feem ntau yog cov protein) thiab cov khoom tsis haum (feem ntau yog cov ntxhia lossis dej). Matrix hauv cov ntaub so ntswg sib txuas ua rau nws cov ntaub so ntswg ntom ntom
