Lysosomes vs Peroxisomes
Lysosomes thiab peroxisomes yog enzymes uas muaj ib qho membranous organelles pom nyob rau hauv eukaryotic hlwb. Lawv txawv ntawm ntau txoj hauv kev suav nrog lawv cov enzymes, qhov loj me thiab cov nyiaj uas lawv nthuav tawm hauv ib lub xov tooj.
YLysosome yog dab tsi?
Lysosome yog ib daim nyias nyias organelle pom hauv eukaryotic hlwb. Ntxiv mus, lysosomes muaj nyob rau hauv yuav luag tag nrho cov tsiaj hlwb tshwj tsis yog cov qe ntshav liab, thiab tag nrho cov eukaryotic cog hlwb thiab fungi. Cov organelles no yog puag ncig-puab, ntom ntom, uas feem ntau muaj lytic enzymes. Lysosomes muaj qhov loj ntawm 0.23 txog 0.5 µm nyob rau hauv txoj kab uas hla thiab suav hais tias yog ultramicroscopic organelles.
Cov lytic enzymes suav nrog ribonuclease, deoxyribonuclease, phosphatase, cathepsin, lysozyme, sulphatases, thiab glycosidases yog khaws cia rau hauv nruab nrab vacuole ntawm lysosome, uas yog nyob ib puag ncig los ntawm ntom granulated stroma. Cov enzymes no feem ntau hu ua acid hydrolases vim tias lawv ua haujlwm ntawm acidic pH, uas qis dua pH 7.
Nws tau xav tias lysosomes yog tsim los ntawm vesicles ntawm Golgi apparatus los yog endoplasmic reticulum. Hauv ib lub cell, plaub hom lysosomes tuaj yeem pom, uas yog; thawj lysosome, theem nrab lysosome, tertiary lysosome, thiab autophagic vacuoles. Lub luag haujlwm tseem ceeb ntawm lysosomes yog kev txav ntawm cov khoom noj los ntawm cov khoom khaws cia thaum tshaib plab, pab txhawb kev zom zaub mov hauv lub cev, kev zom cov kabmob embryonic thaum lub sijhawm metamorphosis (piv txwv li: kev zom ntawm tus Tsov tus tw hauv dipole), tshem tawm cov qub organelles thiab cov hlwb, thiab tswj cov txheej txheem zais cia. cov qog endocrine.
Peroxisome yog dab tsi?
Peroxisomes yog membrane bounded microbodies uas muaj ob peb oxidative enzymes. Ntxiv mus, lawv yog oval zoo li tus organelles nrog ntom homogenous stroma. Lub luag haujlwm tseem ceeb ntawm cov peroxisomes yog tsim thiab decompose hydrogen peroxide thaum lub sij hawm detoxifying ntawm tej molecules.
Feem ntau tuaj yeem muaj xya caum txog pua pua peroxisomes hauv ib lub xov tooj, thiab lawv nyob hauv thaj tsam ntawm 0.5-1.0 µm inch. Lub neej ntawm peroxisome yog li 4-5 hnub. Cov enzymes suav nrog catalase, urate oxidase, D-amino oxidase thiab α-hydroxylic acid oxidase yog synthesized nyob rau hauv ribosomes ntawm ntxhib endoplasmic reticulum. Cov oxidative enzymes ntawm peroxisomes siv oxygen los tshem tawm cov hydrogen molecules, yog li pab kom detoxify qee cov organic molecules xws li cawv. Cov tshuaj tiv thaiv no ua rau hydrogen peroxide, uas thaum kawg degraded los ntawm catalase enzyme hauv peroxisome.
Qhov txawv ntawm Lysosome thiab Peroxisome yog dab tsi?
• Lysosomes muaj hydrolytic enzymes, whereas peroxisomes muaj oxidative enzymes.
• Peroxisomes feem ntau loj dua lysosomes.
• Hauv ib lub cell, muaj 70-100 peroxisomes thiab 15-20 lysosomes tam sim no.
• Peroxisomes yog muab los ntawm endoplasmic reticulum (ER), hos lysosomes ntseeg tau hloov zuj zus los ntawm Golgi apparatus lossis ER.
• Lysosomes pab zom cov cell thiab organelles, whereas peroxisomes pab zom cov tshuaj lom molecules hauv hlwb.
