Vacuoles muaj hydrolytic enzymes rau degrading ntau yam macromoleculesxws li cov proteins, nucleic acids, thiab ntau polysaccharides. Cov qauv, xws li mitochondria, tuaj yeem hloov los ntawm endocytosis mus rau lub vacuole thiab zom rau ntawd. Vim li no ib tug hais txog lytic vacuoles.
Lub vacuole tsim dab tsi?
Ib lub vacuole yog ib qho membrane-bound cell organelle. Hauv cov tsiaj hlwb, vacuoles feem ntau me me thiab pab sequester khib nyiab. Hauv cov nroj tsuag, vacuoles pab tswj cov dej sib npaug. Qee zaum ib lub vacuole tuaj yeem siv feem ntau ntawm qhov chaw sab hauv ntawm cov nroj tsuag.
Lub tshuab nqus tsev vacuole yog dab tsi?
Vacuoles yog cov hnab ntim cov hnab ntim hauv cov cytoplasm ntawm lub xovtooj ntawm tes uas ua haujlwm ntau txoj hauv kev. Hauv cov nroj tsuag paub tab, vacuoles zoo li loj heev thiab tseem ceeb heev hauv kev muab kev txhawb nqa, nrog rau kev ua haujlwm xws li khaws cia, pov tseg pov tseg, tiv thaiv, thiab kev loj hlob.
3 lub luag haujlwm ntawm lub vacuole yog dab tsi?
Tshwj xeeb tshaj yog nyob rau hauv protozoa (ib leeg-celled eukaryotic kab mob), vacuoles yog qhov tseem ceeb cytoplasmic organelles (organelles), ua haujlwm xws li khaws cia, noj, zom zaub mov, tshem tawm, thiab tshem tawm cov dej ntau dhau.
Qhov txawv ntawm vesicle thiab vacuole yog dab tsi?
Vesicles thiab vacuoles yog cov hnab ntim ua ke uas ua haujlwm hauv kev cia thiab thauj. Vacuolesyog me ntsis loj dua vesicles, thiab daim nyias nyias ntawm lub vacuole tsis fuse nrog rau daim nyias nyias ntawm lwm cov cellular Cheebtsam. Vesicles tuaj yeem fuse nrog lwm cov membranes hauv lub cell system (Daim duab 1).
Pom zoo:
Puas yog lub hauv paus vacuole ntawm cov nroj tsuag?
Ntau lub hlwb muaj ib qho loj, ib lub hauv paus vacuole uas feem ntau yuav siv sij hawm ntau ntawm chav hauv cell (80 feem pua lossis ntau dua). Vacuoles hauv cov tsiaj hlwb, txawm li cas los xij, zoo li me me, thiab feem ntau siv los khaws cov khoom ib ntus lossis thauj khoom.
Los ntawm cov khoom tsim thaum lub sij hawm tsim cov bakelite yog?
Nyob rau hauv rooj plaub ntawm bakelite phenol thiab formaldehyde condense los tsim cov monomer muab H2O raws li cov khoom lag luam. Bakelite tseem hu ua co-polymer. Cov tshuaj tiv thaiv: Phenol reacts nrog formaldehyde los tsim o-Hydroxy methyl phenol.
Puas yog cov enzymes ua kom cov tshuaj lom neeg biochemical?
Ntawm ntawm Enzyme Catalyzed Reactions Enzymes yog cov khoom siv roj ntsha. Catalysts txo qis lub zog ua kom muaj zog rau cov tshuaj tiv thaiv. … Yog li enzymes nrawm cov tshuaj tiv thaiv los ntawm kev txo qis zog ua kom. Ntau cov enzymes hloov cov duab thaum substrates khi.
Dab tsi yog digestive enzymes lub siab tsim?
Lipase. Cov enzyme no ua haujlwm ua ke nrog bile, uas koj lub siab tsim tawm, txhawm rau txo cov rog hauv koj cov zaub mov. Yog tias koj tsis muaj lipase txaus, koj lub cev yuav muaj teeb meem nqus cov rog thiab cov vitamins tseem ceeb hauv cov rog (A, D, E, K).
Puas yog cov nroj tsuag carnivorous yog cov tsim khoom lossis cov neeg siv khoom?
As producers, cov nroj tsuag tsim lub hauv paus ntawm yuav luag txhua cov khoom noj hauv ntiaj teb. Carnivorous nroj tsuag zoo li "tig rooj" thaum lawv ua raws li cov neeg siv khoom, gobbling kab, qav, thiab cov tsiaj me me. Puas yog Venus flytrap yog tus neeg siv khoom thiab tsim khoom?
