Qhov txawv ntawm mitochondria thiab kinetoplast yog mitochondria yog eukaryotic cell organelles uas tsim lub zog (ATP). Lub caij no, kinetoplast yog ib lub network ntawm cov DNA ncig nyob rau hauv lub mitochondrion loj, tshwj xeeb hauv protozoa ntawm chav kawm Kinetoplastea.
Eukaryotic hlwb muaj ntau hom cell organelles. Cov organelles sib txawv no ua haujlwm sib txawv hauv cov cell nyob. Ntawm cov no, mitochondria yog ib qho ntawm cov membrane-bound organelles pom nyob rau hauv eukaryotic cell. Lawv yog cov organelles uas yog lub luag hauj lwm rau lub zog (nyob rau hauv daim ntawv ntawm ATP) zus tau tej cov cell. Yog li ntawd, lawv suav hais tias yog lub zog ntawm lub cell. Mitochondria muaj lawv tus kheej genome, uas yog ncig DNA tau los ntawm niam txiv. Kinetoplast yog lub network ntawm ncig DNA pom nyob rau hauv loj mitochondrion ntawm cov kab mob teej tug mus rau chav kawm Kinetoplastida. Yog li ntawd, kinetoplasts tsuas pom nyob rau hauv no eukaryotic subdomain.
Mitochondria yog dab tsi?
Mitochondria yog ob chav membrane-bound eukaryotic cell organelles. Lawv yog cov powerhouses ntawm eukaryotic hlwb. Cellular respiration tshwm sim nyob rau hauv lub mitochondria. Nws yog cov txheej txheem uas tsim lub zog xav tau rau txhua qhov txheej txheem ntawm tes. Ntawm peb cov txheej txheem tseem ceeb ntawm kev ua pa ntawm tes, ob txheej txheem tshwm sim hauv mitochondria. Mitochondria muaj nyob rau hauv lub cell cytoplasm. Tsis tas li ntawd, lawv yog rod-shaped organelles. Mitochondria muaj lawv tus kheej genomes los ntawm niam txiv. Muaj ob phospholipid bilayers hu ua txheej membrane thiab puab membrane nyob rau hauv mitochondria. Lub puab daim nyias nyias yog compartmentalized rau hauv cristae thiaj li yuav ua rau kom qhov chaw nto rau oxidative phosphorylation. Mitochondrial matrix yog qhov chaw uas nyob rau hauv lub puab membrane.
Daim duab 01: Mitochondrion
Tus naj npawb ntawm mitochondria pom nyob rau hauv ib lub xovtooj ntawm tes txawv raws li lub cev, cov ntaub so ntswg thiab hom cell. Qee lub hlwb, tshwj xeeb tshaj yog cov qe ntshav liab, tsis muaj mitochondria thaum qee lub hlwb zoo li lub siab hlwb muaj ntau dua 2000 mitochondria ib lub cell. Ntxiv nrog rau kev tsim cov ATP (lub zog ntawm tes), mitochondria koom nrog lwm cov haujlwm xws li xov tooj ntawm tes, kev sib txawv ntawm tes, kev loj hlob ntawm tes, kev tuag ntawm tes, thiab tsim hluav taws xob.
Kinetoplast yog dab tsi?
Kinetoplast yog lub network ntawm cov DNA ncig pom nyob rau hauv loj mitochondria ntawm chav kawm Kinetoplastida ntawm Excavata. Yog li ntawd, kinetoplast muaj ntau cov ntawv luam ntawm mitochondrial genome. Nws yog feem ntau yog ib tug disk-zoo li tus qauv. Kinetoplast ncig DNA muaj nyob rau hauv ob hom: maxicircles thiab minicircles. Maxicircles yog 20 thiab 40kb qhov loj me thaum lub voj voog me me yog 0.5 thiab 1kb loj. Feem ntau, muaj ntau txhiab lub voj voog thaum muaj ob peb lub kaum os maxicircles hauv mitochondrion. Kinetoplast DNA muaj nyob rau hauv mitochondrial matrix perpendicular mus rau axis ntawm flagellum.
Daim duab 02: Kinetoplast
Muaj qhov sib txawv hauv kinetoplast ntawm kinetoplastids raws li kev npaj thiab qhov chaw ntawm lawv kDNA. Thiab, qhov kev hloov pauv no yuav pab tau thaum txiav txim siab txog kev sib raug zoo ntawm cov hom kinetoplastids.
Dab tsi yog qhov zoo sib xws ntawm Mitochondria thiab Kinetoplast?
- Mitochondria thiab kinetoplasts tsuas pom muaj nyob hauv eukaryotes.
- Kinetoplasts yog ncig DNA pom nyob rau hauv loj mitochondria ntawm Kinetoplastida unicellular kab mob.
Qhov txawv ntawm Mitochondria thiab Kinetoplast yog dab tsi?
Mitochondria yog eukaryotic, membrane-bound organelles tam sim no nyob rau hauv cytoplasm, thaum kinetoplast yog ib ncig DNA pom nyob rau hauv mitochondria ntawm Kinetoplastida kab mob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm mitochondria thiab kinetoplast. Tsis tas li ntawd, thaum mitochondria yog cell organelles, kinetoplast yog DNA.
Ntxiv mus, lwm qhov sib txawv ntawm mitochondria thiab kinetoplast yog tias mitochondria yog tus pas nrig, qhov kinetoplast yog disk-puab. Tsis tas li ntawd, mitochondria tsim ATP rau cellular txheej txheem ntawm cellular respiration, whereas kinetoplast tshwm sim li mitochondria DNA nyob rau hauv unicellular kinetoplastids.
Summary – Mitochondria vs Kinetoplast
Mitochondria yog lub zog ntawm eukaryotic hlwb. Lawv yog cov membrane-bound cell organelles nyob rau hauv lub cytoplasm. Cellular respiration tshwm sim nyob rau hauv mitochondria. Ntxiv mus, muaj mitochondrial genome nyob rau hauv txhua mitochondrion. Kinetoplast yog lub network ntawm cov voj voog DNA tam sim no nyob rau hauv loj mitochondrion ntawm ib pab pawg tshwj xeeb hu ua Kinetoplastida. Kinetoplast qauv yog feem ntau disk-puab. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm mitochondria thiab kinetoplast.
