Function thiab tshuab . Lub enzyme ua haujlwm los ntawm kev tawm tsam, hydrolyzing, thiab rhuav tshem glycosidic bonds hauv peptidoglycans. Lub enzyme tseem tuaj yeem rhuav tshem glycosidic bonds hauv chitin, txawm tias tsis zoo li chitinases tseeb.
Hauv qhov no, lysozyme ua haujlwm li cas?
Lysozyme yog ib qho tshwj xeeb enzyme pom nyob rau hauv kua muag, qaub ncaug, hws, thiab lwm yam dej hauv lub cev. Lwm cov mucosal linings, xws li lub qhov ntswg kab noj hniav, kuj muaj lysozyme . Nws rhuav tshem cov kab mob uas sim nkag mus rau peb lub cev los ntawm cov kab no. Nyob rau hauv cov ntaub ntawv ntawm kua muag, lawv tiv thaiv peb ob lub qhov muag los ntawm cov kab mob invaders.
Kuj Paub, lysozyme siv rau dab tsi? Lysozyme , yog ib qho ntawm cov muaj zog tshaj plaws antibacterial thiab antiviral compounds paub rau txiv neej, tau siv hauv khoom noj thiab tshuaj rau ntau tshaj peb xyoo lawm vim nws ib txwm inhibits kev loj hlob ntawm ntau yam kab mob spoilage, ua rau kom noj qab nyob zoo txee lub neej thiab ua kom cov zaub mov muaj kev ruaj ntseg. Nws kuj txhawb kev tiv thaiv kab mob.
Ua kom pom qhov no, lysozyme yog qhov twg nws pom nws txoj haujlwm yog dab tsi?
Lysozyme . Lysozyme , cov enzyme pom nyob rau hauv secretions (kua muag) ntawm cov qog lacrimal ntawm cov tsiaj thiab nyob rau hauv qhov ntswg mucus, gastric secretions, thiab qe dawb. Nrhiav tau Xyoo 1921 los ntawm Sir Alexander Fleming, lysozyme catalyzes qhov kev puas tsuaj ntawm qee cov carbohydrates pom nyob rau hauv lub cell phab ntsa ntawm tej yam kab mob (piv txwv li, cocci).
Lub luag haujlwm ntawm lysozyme hauv qe dawb yog dab tsi?
Nws yog ib qho enzyme paub txog nws muaj peev xwm kom degrade lub polysaccharide architecture ntawm ntau yam cell phab ntsa, feem ntau rau lub hom phiaj ntawm kev tiv thaiv tiv thaiv kab mob. Cov qauv ntawm hen qe dawb (HEW) lysozyme, qhov tseem ceeb ntawm tsab xov xwm no, yog qhia rau sab xis.

Koj yuav txiav txim siab li cas yog tias kev sib raug zoo yog qhov ua haujlwm ntawm daim duab?
LUS TEB: Cov lus teb piv txwv: Koj tuaj yeem txiav txim siab seb txhua lub ntsiab lus ntawm lub npe yog ua ke nrog ib lub ntsiab lus ntawm qhov ntau. Piv txwv li, yog muab ib daim duab, koj tuaj yeem siv txoj kab ntsug; Yog hais tias ib txoj kab ntsug hla cov duab ntau dua ib zaug, ces qhov kev sib raug zoo uas cov duab sawv cev tsis yog ib qho haujlwm
Yuav ua li cas yog qhov kev txiav txim ntawm cellular lub koom haum los ntawm tsawg tshaj plaws mus rau loj?
Cov theem, los ntawm qhov tsawg tshaj plaws mus rau loj, yog: molecule, cell, ntaub so ntswg, lub cev, lub cev, kab mob, kab mob, pej xeem, zej zog, ecosystem, biosphere
Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Lub hom phiaj ntawm kev txiav txim siab ntawm ib qho kev sib npaug tas li yog dab tsi?
Lub hom phiaj ntawm qhov kev sim no yog txhawm rau txiav txim siab qhov sib npaug tsis tu ncua rau cov tshuaj tiv thaiv. Fe3+ + SCN. & rho tawm; ⇌ FeSCN2+ thiab saib seb qhov tas mus li yog qhov tseeb tib yam hauv qab sib txawv. tej yam kev mob
Yuav ua li cas koj txiav txim siab uas yog tus nqi txiav txim kauj ruam?
Tus nqi txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws ntawm cov tshuaj tiv thaiv tshuaj uas txiav txim siab qhov nrawm (tus nqi) uas tag nrho cov tshuaj tiv thaiv ua tiav. Teb Tus nqi txiav txim kauj ruam yog kauj ruam thib ob vim nws yog kauj ruam qeeb. 2NO + 2H2 → N2 + 2H2O. Cov intermediates hauv cov tshuaj tiv thaiv no yog N2O2 thiab N2O
