Cov txheej txheem ntawm tes tsim cov txheej txheem tseem ceeb uas cuam tshuam nrog cov txheej txheem nyuaj ntawm cov tshuaj tiv thaiv biochemical thiab cov kev taw qhia. Yuav kom tsim nyog cell function, cov txheej txheem yuav tsum tau tswj nruj nruj.
Xav txog qhov no, dab tsi yog 5 cell txheej txheem?
Cell Functions thiab Txheej Txheem
- Osmosis.
- Cellular Energy Production.
- Cell Thauj.
- Homeostasis.
- Anaerobic Ua pa.
- Aerobic Ua pa.
- Cell Diffusion.
- Photosynthesis.
Ib yam li ntawd, peb txheej txheem dab tsi tshwm sim hauv lub cell? Peb tuaj yeem faib cellular ua pa rau hauv peb txheej txheem metabolic: glycolysis , cov Krebs lub voj voog , thiab oxidative phosphorylation . Txhua qhov no tshwm sim hauv ib cheeb tsam tshwj xeeb ntawm lub cell. Glycolysis tshwm sim hauv cytosol. Cov Krebs lub voj voog tshwm sim nyob rau hauv lub matrix ntawm mitochondria.
Kuj Paub, plaub txheej txheem ntawm tes yog dab tsi?
Cov plaub qhov tseem ceeb txheej txheem los ntawm uas ib tug multicellular kab mob yog tsim: cell kev loj hlob, cell tshwj xeeb, cell kev sib tham, thiab cell kev txav mus los.
Lub hom phiaj ntawm cov txheej txheem cellular yog dab tsi?
Cov Lub hom phiaj Cellular Ua pa Cellular ua pa yog qhov txheej txheem los ntawm cov hlwb hauv cov nroj tsuag thiab tsiaj txhu zom cov suab thaj thiab tig mus rau hauv lub zog, uas yog siv los ua haujlwm ntawm lub cellular qib. Cov lub hom phiaj ntawm cellular Kev ua pa yog yooj yim: nws muab cov hlwb nrog lub zog uas lawv xav tau muaj nuj nqi.

Dab tsi yog cov txheej txheem uas tsim cov ntawv luam tshiab ntawm cov kab mob caj ces?
Cov txheej txheem ntawm DNA replication tsim ib daim qauv tshiab ntawm cov kab mob cov ntaub ntawv caj ces kom dhau mus rau lub cell tshiab. Dawb ntab nucleotides yog txuam nrog lawv cov lus qhuas los ntawm ib qho enzyme hu ua polymerase. Cov no yog 'lub tsev.' Lawv sib sau ua ke DNA tshiab strand nrog txhua tus qub strands
Cov xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
Dab tsi yog txheej txheem spontaneous thiab non-spontaneous txheej txheem?
Cov txheej txheem spontaneous yog ib qho uas tshwm sim yam tsis muaj kev cuam tshuam ntawm sab nraud. Ib txoj kev uas tsis yog tshwm sim yuav tsis tshwm sim yog tias tsis muaj kev cuam tshuam ntawm sab nraud
Cov txheej txheem ntawm kev sib koom tes yog dab tsi?
Coevolution, tus txheej txheem ntawm reciprocal evolutionary hloov uas tshwm sim ntawm khub ntawm hom los yog ntawm cov pab pawg neeg ntawm hom thaum lawv sib cuam tshuam nrog ib leeg. Cov kev ua ntawm txhua hom uas koom nrog hauv kev sib cuam tshuam siv kev xaiv xaiv rau lwm tus
Cov txheej txheem twg yog txheej txheem endothermic?
Cov txheej txheem endothermic yog ib qho txheej txheem uas xav tau lossis nqus lub zog los ntawm nws qhov chaw nyob ib puag ncig, feem ntau yog ua kom sov. Nws yuav yog cov txheej txheem tshuaj, xws li dissolving ammonium nitrate hauv dej, lossis cov txheej txheem ntawm lub cev, xws li melting ntawm cov dej khov nab kuab
