Obligate anaerobes tsis muaj superoxide dismutase thiab catalase thiab/los yog peroxidase, thiab yog li ntawd raug oxidation tuag los ntawm ntau cov pa radicals thaum lawv raug O 2.

Pob anaerobes xav tau oxidase?

Ib oxidase zoo kab mob tej zaum yuav yog ib qho obligate aerobe, facultative anaerobe, los yog microaerophile.

Vim li cas obligate anaerobes tsis xav tau catalase?

Nws yog vim lawv tsis muaj cov enzymes xws li superoxide dismutase thiab catalase uas yuav hloov cov superoxide tuag tsim hauv lawv cov hlwb vim muaj oxygen. Obligate anaerobes tuaj yeem siv fermentation lossis anaerobic ua pa.

Yuav ua li cas anaerobe tsim?

Tsis zoo li ntau cov kab mob uas muaj kev vam meej hauv qhov chaw muaj oxygen, lub luag haujlwm anaerobes tsis muaj ob peb lub ntsiab lus tseem ceeb uas yuav tsum tau ua kom tshem tawm cov pa oxygen hauv lub cell. Oxygen nws tus kheej, nyob rau hauv lub xub ntiag ntawm dej, tsim ntau byproducts suav nrog hydrogen peroxide (H2O2).

Yuav ua li cas cov hauv qab no yog obligate anaerobe?

methane-producing archaea (methanogens), yog hu ua obligate anaerobes vim lawv lub zog tsim cov txheej txheem metabolic tsis ua ke nrog kev noj cov pa. Qhov tseeb, muaj cov pa oxygen ua rau qee yam ntawm lawv cov enzymes tseem ceeb.
