A microbody (los yog cytosome) yog ib hom kab mob uas muaj nyob hauv cov hlwb ntawm cov nroj tsuag, protozoa, thiab tsiaj txhu. Organelles hauv tsev neeg microbody suav nrog peroxisomes, glyoxysomes, glycosomes thiab hydrogenosomes. Hauv cov kab mob vertebrates, microbodies tshwj xeeb tshaj yog nyob rau hauv lub siab thiab lub raum
Puas microbodies muaj nyob rau hauv prokaryotes?
Qhov chaw: Lawv muaj nyob hauv yuav luag txhua lub hlwb eukaryotic. Lawv feem ntau pom nyob ze ntawm endoplasmic reticulum (ER), thiab qee zaum nyob ze mitochondria thiab plastids. Lawv tsis nyob hauv cov hlwb prokaryotic.
Dab tsi yog microbodies nyob rau hauv ib lub cell?
Microbodies, pom nyob rau hauv hlwb, yog spherical, membrane-bound organelles uas ua si ib feem ntawm photorespiration thiab hloov cov rog rau hauv sucrose. Peroxisomes thiab glyoxysomes yog ob hom microbodies loj hauv cov nroj tsuag.
glyoxysomes nyob qhov twg?
Glyoxysomes yog tshwj xeeb peroxisomes pom nyob rau hauv cov nroj tsuag (tshwj xeeb tshaj yog nyob rau hauv cov rog cia cov ntaub so ntswg ntawm germinating noob) thiab kuj nyob rau hauv filamentous fungi. Cov noob uas muaj roj thiab roj muaj xws li pob kws, taum pauv, paj noob hlis, txiv laum huab xeeb thiab taub dag.
Cov kab mob microbodies hu ua dab tsi?
Peroxisomes, glyoxysomes, thiab glycosomes yog cov cell organelles uas muaj npe hu ua microbodies. Ntawm cov no, peroxisomes tau dav thiab txhais tau tias yog microbodies uas muaj tsawg kawg yog ib qho hydrogen peroxide-tsim oxidase ua ke nrog catalase, uas decomposes hydrogen peroxide sab khoom.
