Paj fermentation Poov xab tuaj yeem muaj sia nyob thiab tsis muaj oxygen (1). Nyob rau hauv lub xub ntiag ntawm oxygen, poov xab raug aerobic ua pathiab hloov cov carbohydrates (qab zib qhov chaw) mus rau carbon dioxide thiab dej.
Puas yog poov xab siv aerobic ua pa?
Yeast, feem ntau, qhia ntau yam kev nyiam ntawm metabolic hais txog nws hom kev ua pa (aerobic lossis anaerobic) txawm tias muaj oxygen. Saccharomyces poov xab, tshwj xeeb, tau raug sau tseg tias nkag mus rau fermentative ua pa txawm nyob rau hauv aerobic tej yam kev mob mus rau txawv degrees.
Pob poov xab loj hlob aerobically lossis anaerobically?
Cov poov xab zoo li qub tuaj yeem loj hlob tau aerobically, nyob rau hauv muaj oxygen lossis anaerobically, thaum tsis muaj oxygen. Raws li kev loj hlob aerobic lawv tuaj yeem txhawb kev loj hlob los ntawm oxidizing cov pa roj carbon yooj yim, xws li ethanol, acetate lossis glycerol.
Puas yog poov xab ua pa anaerobic?
Anaerobic respiration in poov xab
yeast tau hloov siv ua pa anaerobic kom ntseeg tau tias nws muaj sia nyob. Ethanol thiab carbon dioxide yog tsim. Cov poov xab kuj siv tau los ua mov ci. Cov poov xab respires siv cov piam thaj hauv cov suab thaj uas tau ntxiv rau hauv khob noom cookie.
Vim li cas cov poov xab tsis siv aerobic ua pa?
Ib qho tseem ceeb ntawm cov poov xab hauv khob cij
Cov poov xab ua haujlwm ua tus neeg sawv cev hauv cov qhob cij, hloov cov suab thaj hauv khob noom cookie rau hauv roj, uas tsim cov npuashauv cov ncuav. … Txawm li cas los xij, vim tias thaum kawg cov poov xab yuav hloov ntawm aerobic mus rau ua pa tawm anaerobic, cov poov xab yuav khiav tawm ntawm cov khoom noj - oxygen.
