Qhov sib txawv tseem ceeb ntawm chemotaxis thiab phagocytosis yog qhov chemotaxis yog ib qho kev txav chaw ntawm cov hlwb los yog cov kab mob raws li cov tshuaj lom neeg concentration gradient thaum phagocytosis yog ib qho cuab yeej uas cuam tshuam cov kab mob txawv teb chaws thiaj li ua rau tsis zoo lossis ua kom puas tsuaj.
Leukocytes yog cov hlwb tseem ceeb ntawm lub cev tiv thaiv kab mob. Lawv yog cov qe ntshav dawb. Qee cov leukocytes yog phagocytes. Phagocytes siv phagocytosis los engulf txawv teb chaws hais. Monocytes, neutrophils, thiab macrophages yog qee qhov piv txwv ntawm phagocytes. Txhawm rau kom ncav cuag antigens lossis txawv teb chaws, phagocytes siv chemotaxis. Chemotaxis yog qhov txav ntawm cov hlwb lossis cov kab mob mus rau lossis tawm ntawm cov tshuaj stimuli. Tsis tas li ntawd, phagocytes thiab lub cev tiv thaiv kab mob txav mus rau qhov chaw kis kab mob, cov ntaub so ntswg raug mob thiab tiv thaiv kev tiv thaiv kab mob los ntawm chemotaxis.
Chemotaxis yog dab tsi?
Chemotaxis yog kev txav ntawm cov hlwb lossis cov kab mob mus rau lossis tawm ntawm cov tshuaj stimuli. Nws yog ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws uas siv los ntawm phagocytes txhawm rau txhawm rau nkag mus rau hauv qhov chaw kis kab mob lossis cov ntaub so ntswg raug mob. Ntxiv mus, chemotaxis tseem ceeb heev rau ntau hom hlwb thiab kab mob. Cov kab mob nrhiav zaub mov los ntawm chemotaxis. Tsis tas li ntawd, lawv khiav tawm ntawm cov tshuaj phem vim yog chemotaxis. Hauv cov kab mob siab dua, cov phev ua luam dej ntawm lub qe qe vim yog chemotaxis.
Daim duab 01: Chemotaxis
Chemotaxis tuaj yeem yog qhov zoo chemotaxis lossis tsis zoo chemotaxis. Yog hais tias cov kev taw qhia ntawm lub zog yog mus rau cov tshuaj stimulus, nws yog zoo chemotaxis. Txawm li cas los xij, yog tias nws nyob deb ntawm cov tshuaj stimulus, nws yog qhov tsis zoo chemotaxis. Chemoattractants pab txhawb chemotaxis zoo thaum chemorepellents pab txhawb chemotaxis tsis zoo.
Phagocytosis yog dab tsi?
Phagocytosis yog ib qho kev ua haujlwm los ntawm qee lub hlwb lossis cov kab mob kom nkag mus lossis nkag mus rau cov khoom txawv teb chaws. Cov hlwb uas siv phagocytosis yog hu ua phagocytes. Ntau cov qe ntshav dawb yog phagocytes. Tshwj xeeb tshaj yog, neutrophils, monocytes, thiab macrophages ua raws li phagocytes rau engulf invaders xws li kab mob, kab mob, co toxins, thiab lwm yam. Nws yog ib hom ntawm endocytosis txheej txheem.
Daim duab 02: Phagocytosis
Los ntawm phagocytosis, cov khoom sib xyaw ua ke hauv cov qauv hu ua phagosome. Thaum lawv nyob rau hauv phagosome, nws fuses nrog ib tug lysosome thiab tsim ib tug phagolysosome. Tom qab ntawd, siv cov lysosome hydrolase enzymes, cov khoom hauv phagosome tau degraded thiab puas.
Kev sib raug zoo ntawm Chemotaxis thiab Phagocytosis yog dab tsi?
Phagocytes tsiv mus rau qhov chaw kis kab mob thiab raug mob los ntawm chemotaxis
Qhov txawv ntawm Chemotaxis thiab Phagocytosis yog dab tsi?
Chemotaxis yog kev taw qhia ntawm cov hlwb thiab qee yam kab mob mus rau lossis deb ntawm cov tshuaj stimulus. Phagocytosis yog txheej txheem engulfs txawv teb chaws hais thiab rhuav tshem lawv thaum lub sij hawm cev xeeb tub. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm chemotaxis thiab phagocytosis. Tsis tas li ntawd, muaj ob hom chemotaxis ua qhov zoo chemotaxis thiab tsis zoo chemotaxis. Phagocytosis tsis muaj hom.
Tsis tas li ntawd, chemotaxis tshwm sim vim muaj tshuaj stimulus thaum phagocytosis tsis tshwm sim vim muaj kev txhawb nqa. Yog li, qhov no kuj yog qhov sib txawv ntawm chemotaxis thiab phagocytosis. Qhov sib txawv ntxiv ntawm chemotaxis thiab phagocytosis yog qhov tsis zoo li chemotaxis, phagocytosis tsis cuam tshuam rau kev taw qhia. Tsis tas li ntawd, kev koom tes ntawm lysosomes hauv cov proess ua rau muaj qhov sib txawv ntawm chemotaxis thiab phagocytosis. Qhov ntawd yog; lysosomes koom nrog hauv phagocytosis whereas chemotaxis tsis koom nrog lysosomes.
Cov hauv qab no infographic smmarizes qhov txawv ntawm chemotaxis thiab phagocytosis.
Summary – Chemotaxis vs Phagocytosis
Chemotaxis yog lub zog ntawm cov hlwb lossis cov kab mob hauv cov lus teb rau cov tshuaj stimulus. Muaj ob hom chemotaxis li zoo chemotaxis thiab tsis zoo chemotaxis. Chemotaxis tsuas yog ib txoj hauv kev ua haujlwm. Ntxiv mus, nws ua haujlwm raws li cov tshuaj stimulus. Ntawm qhov tod tes, phagocytosis yog txheej txheem siv los ntawm phagocytes lossis qee lub cev tiv thaiv kab mob thiab qee yam kab mob txhawm rau txhawm rau txhawm rau cuam tshuam cov khoom txawv teb chaws thiab tshem tawm ntawm lub cev. Nws yog ib hom kab mob endocytosis uas ua rau cov khoom siv hauv cov qauv hu ua phagosome. Yog li, qhov no yog qhov txawv ntawm chemotaxis thiab phagocytosis.
