Cov pyrenoid, cov qauv ntom ntom sab hauv lossis ib sab ntawm chloroplasts ntawm qee cov algae, muaj ntau ntawm ribulose biphosphate carboxylase, ib qho ntawm cov enzymes tsim nyog hauv photosynthesis rau carbon fixation thiab yog li qab zib tsim. Starch, ib daim ntawv khaws cov piam thaj, feem ntau pom nyob ib ncig ntawm pyrenoids.
Qhov twg hauv qab no yog tsim los ntawm pyrenoids Mcq?
8. Qhov twg hauv qab no yog tsim nyob rau hauv pyrenoids? Nqe lus piav qhia: Cov chloroplasts ntawm ntsuab algae feem ntau muaj cov cheeb tsam ntom ntom hu ua pyrenoids, uas tsim cov hmoov txhuv nplej siab granules.
Pyrenoids pom nyob qhov twg?
Pyrenoids yog cov sub-cellular micro-compartments pom nyob rau hauv chloroplasts ntawm ntau algae, thiab nyob rau hauv ib pab pawg neeg ntawm cov av, cov hornworts. Pyrenoids cuam tshuam nrog kev ua haujlwm ntawm cov pa roj carbon-concentrating mechanism (CCM).
Puas yog spirogyra pyrenoids nyob rau?
Pyrenoids yog sub-cellular microcompartments uas pom nyob rau hauv cov chloroplasts ntawm ntau algae, zoo li Spirogyra thiab hauv ib pawg ntawm cov nroj tsuag hauv av, hornworts. Hauv cov algae no, pyrenoids tej zaum ua haujlwm los kho cov pa roj carbon. Hauv lwm cov algae, pyrenoids yog qhov chaw ntawm carbohydrate (feem ntau starch) cia.
Qhov twg hauv qab no pom muaj nyob hauv pyrenoids?
Pyrenoids tshwm sim hauv ntau ntawm cov algae thiab cuam tshuam nrog cov chloroplasts. Ib txhia ntawm lawv paub tias muajRubisco, enzyme uas catalyzes kev koom ua ke ntawm inorganic CO2 rau hauv carbohydrates. Hauv cov algae no, pyrenoids tej zaum yuav ua haujlwm los kho cov pa roj carbon.
