Vim tias hydrogen peroxide ua rau lub cev tsis zoo, peroxisomes kuj muaj cov enzyme catalase, uas decomposes hydrogen peroxide los ntawm kev hloov mus rau dej los yog siv nws los oxidize lwm cov organic compound..
Pob lysosomes muaj catalase?
Lysosomes degrade phagocytosed cov khoom thiab hnav-tawm ntawm tes. Lub peroxisome yog lwm daim nyias nyias-bounded vesicle, nrog ib txoj kab uas hla ntawm li 0.5 μm. Nws muaj oxidative enzymes xws li catalase , d-amino acid oxidase, thiab urate oxidase. Zoo li mitochondria, cov peroxisomes yog qhov chaw loj ntawm O2 siv.
Koj puas ntseeg tias cellular organelle yuav muaj cov catalase tshaj plaws?
Peroxisomes yog cov organelles me uas muaj cov enzymes uas oxidize ntau cov organic tebchaw, tsim cov hydrogen peroxide. Cov tshuaj lom no tau hloov mus rau hauv dej thiab oxygen los ntawm catalase, kuj tseem muaj nyob rau hauv ntau cov organelles.
Puas yog peroxisomes hauv txhua lub hlwb eukaryotic?
Peroxisome Keeb Kwm thiab Kev faib tawm
Peroxisomes muaj nyob rau hauv tag nrho cov eukaryotes, los ntawm ib leeg- thiab ntau cov kab mob, mus rau cov nroj tsuag thiab tsiaj txhu. Tsis zoo li mitochondria, nuclei, thiab chloroplasts, peroxisomes tsis muaj DNA.
Cov tsiaj cell organelle twg muaj cov enzymes uas hloov hydrogen peroxide h2o2 rau dej?
Yog li ntawd, peroxisomeskuj muaj enzymes xws li catalase uas hloov hydrogen peroxide rau dej thiab oxygen, yog li neutralizing cov tshuaj lom. Ua li ntawd, peroxisomes muab qhov chaw nyab xeeb rau oxidative metabolism ntawm qee cov molecules.

Puas yog cov dab dab dab dab dab dab dab dab dab dab dab dab?
Myth: Ib tug dab tshos tsis yog neeg ncaj ncees yog tiasnws haum yog. Fact: Tu siab, qhov no yog ib lo lus tsis tseeb uas tau raug perpetuated los ntawm aversive trainers. Txawm hais tias haum rau lub caj dab kom zoo khawb rau hauv cov tawv nqaij rhiab nyob ib ncig ntawm lub caj dab, uas ua rau muaj kev puas tsuaj loj rau cov thyroid, esophagus, thiab trachea.
Dab tsi ntawm cov hauv qab no yog ib feem ntawm cov turkish straits?
Lawv muaj tus Dardanelles thiab Bosphorus. Cov straits yog nyob ntawm qhov kawg ntawm Hiav Txwv Marmara. Cov straits thiab Hiav txwv Marmara yog ib feem ntawm lub hiav txwv sovereign thaj tsam ntawm Qaib Cov Txwv thiab raug rau tsoom fwv ntawm sab hauv dej.
Dab tsi ntawm cov hauv qab no yog cov kua qaub uas muaj zog tshaj chloroacetic acid?
Yog li, los ntawm cov kev xaiv tau muab, trichloroacetic acid yuav yog cov kua qaub uas muaj zog tshaj plaws vim tias muaj peb chlorine atoms tam sim no ntawm tib cov pa roj carbon uas yuav cuam tshuam cov nqi tsis zoo tshaj plaws thiab ua rau Qhov ruaj khov tshaj plaws carboxylate ion.
Dab tsi ntawm cov hauv qab no yuav tsum yog qhov kev xav ntawm txoj kev kos npe rov qab?
Yuav tsum tsis txhob muaj kev nkag tebchaws mus lossis kev tsiv teb tsaws chaw tawm ntawm cov pejxeem. Yuav tsum tsis muaj kev tuag ntawm lub cim thiab lub sijhawm rov qab los. Kev paub txog kev cim yuav tsum tsis txhob ua rau ib tus neeg ntau dua lossis tsawg dua yuav rov qab tau.
Dab tsi ntawm cov hauv qab no yog qhov tshwm sim ntawm kev sib ntaus sib tua ntawm lub pas dej brandywine?
Cov txiaj ntsig ntawm Kev Sib Tw ntawm Brandywine Creek yog dab tsi? Washington tsuas yog sim ncua kev ntes Philadelphia kom nws ua tiav li no. Cov tub rog Asmeskas tsis tau poob siab ntau thiab lawv tau khiav tawm ntawm British. Washington tseem tuaj yeem kawm los ntawm nws qhov yuam kev ntawm kev tso nws txoj cai sab xis qhib.
