ATP muaj phosphate pawg, ribose thiab adenine. Nws lub luag haujlwm hauv cellular ua pa yog tseem ceeb vim nws yog lub zog txiaj ntawm lub neej. Lub synthesis ntawm ATP absorbs zog vim ntau ATP yog tsim tom qab.
Xav txog qhov no, ATP lub luag haujlwm hauv cellular respiration yog dab tsi?
ATP . Tshwj xeeb, thaum cellular ua pa , lub zog khaws cia hauv qabzib yog pauv mus rau ATP (Daim duab hauv qab no). ATP , los yog adenosine triphosphate, yog tshuaj zog uas lub cell siv tau. Nws yog cov molecule uas muab lub zog rau koj lub hlwb ua haujlwm, xws li txav koj cov leeg thaum koj taug kev hauv txoj kev.
Ib yam li ntawd, yog vim li cas ATP Cov khoom tseem ceeb ntawm kev ua pa ntawm tes? Cov thawj "lub hom phiaj" ntawm Cellular Ua pa yog sau lub zog los ntawm cov piam thaj thiab lwm cov roj carbon-based molecules uas muaj zog thiab siv los ua ATP , uas yog universal zog molecule. Qee lub zog poob raws li qhov kub hauv qhov kev hloov pauv no.
Kuj Paub, ATP yog dab tsi thiab vim li cas nws tseem ceeb?
ATP sawv cev rau adenosine triphosphate. Nws yog ib qho molecule pom nyob rau hauv lub hlwb ntawm cov kab mob nyob. Nws yog hais tias yuav heev tseem ceeb vim nws thauj lub zog tsim nyog rau tag nrho cov cellular metabolic kev ua ub no. ATP muaj ib tug adenine molecule thiab peb phosphate molecules.
Vim li cas nws tseem ceeb heev rau lub cell ua ATP los ntawm kev ua pa ntawm tes?
Cellular ua pa yog tus txheej txheem los ntawm cov tshuaj zog ntawm "zaub mov" molecules raug tso tawm thiab ib feem ntawm kev ntes nyob rau hauv daim ntawv ntawm ATP . Cov saw hlau thauj hluav taws xob tso cai rau kev tso tawm ntau ntawm cov tshuaj siv hluav taws xob khaws cia hauv qhov txo qis NAD + (NADH) thiab txo FAD (FADH 2).

Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev taw qhia ntawm tes los ntawm kev sib cuag lub cev ncaj qha?
Kev taw qhia kuj tshwm sim ntawm cov hlwb uas yog kev sib cuag ntawm lub cev. Kev sib cuam tshuam ntawm cov proteins ntawm qhov chaw ntawm cov hlwb tuaj yeem ua rau muaj kev hloov pauv hauv cov cwj pwm ntawm tes. Piv txwv li, cov proteins nyob rau saum npoo ntawm T-cells thiab antigen nthuav tawm cov hlwb sib cuam tshuam los ua kom muaj kev taw qhia hauv T-cells
Txoj cai ntawm kev txuag huab hwm coj yog dab tsi thiab vim li cas nws tseem ceeb?
Txoj cai ntawm kev txuag ntawm huab hwm coj tseem ceeb heev rau kev kawm thiab tsim cov tshuaj tiv thaiv. Yog tias cov kws tshawb fawb paub txog qhov ntau thiab cov cim ntawm cov tshuaj reactants rau ib qho tshuaj tiv thaiv, lawv tuaj yeem kwv yees tus nqi ntawm cov khoom uas yuav ua
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
Kev xaiv permeability yog dab tsi thiab vim li cas nws tseem ceeb rau cov hlwb?
Selective permeability yog ib yam khoom ntawm cellular daim nyias nyias uas tsuas tso cai rau tej molecules nkag los yog tawm ntawm lub cell. Qhov no yog qhov tseem ceeb rau lub xov tooj ntawm tes kom tswj hwm nws cov kev txiav txim sab hauv tsis hais txog kev hloov pauv rau ib puag ncig
