Lub voj voog citric acid yog tswj los ntawm cov cov enzymes uas catalyze cov tshuaj tiv thaiv uas ua rau thawj ob molecules ntawm NADH. Cov no cov enzymes isocitrate dehydrogenase thiab α-ketoglutarate dehydrogenase. Thaum muaj cov qib ATP thiab NADH txaus, tus nqi ntawm cov tshuaj tiv thaiv no txo qis.

Ntawm no, dab tsi yog lub luag haujlwm ntawm enzymes hauv photosynthesis thiab ua pa?

Enzymes yog cov proteins uas ua raws li catalysts rau cov tshuaj tiv thaiv, xws li cov hauv cellular ua pa . Lawv ua rau kom muaj qhov tshwm sim los ntawm kev txo qis lub zog xav tau rau qhov tshwm sim tshwm sim. Hauv cov txheej txheem, cov enzymes tshuav tsis hloov los ntawm cov tshuaj tiv thaiv. Cov txiaj ntsig molecules los ntawm cov tshuaj tiv thaiv yog hu ua cov khoom.

Ib tug kuj yuav nug, cov proteins koom nrog hauv kev ua pa ntawm tes li cas? Thaum koj noj cov proteins Nyob rau hauv cov zaub mov, koj lub cev yuav tsum zom lawv mus rau hauv cov amino acids ua ntej lawv yuav ua tau siv los ntawm koj lub hlwb. Feem ntau, cov amino acids tau siv dua thiab siv ua tshiab cov proteins , tsis oxidized rau roj. Txhawm rau nkag cellular ua pa , amino acids yuav tsum xub muab lawv cov amino pawg tshem tawm.

Hauv qhov no, dab tsi txheej txheem tswj cellular respiration?

Cellular ua pa yog tswj los ntawm ntau txoj kev. Cov piam thaj nkag mus rau hauv lub cell yog tswj los ntawm kev thauj cov proteins uas pab cov piam thaj nkag mus rau hauv cov cell membrane. Feem ntau ntawm kev tswj ntawm lub cov txheej txheem ua pa yog ua tiav los ntawm kev tswj cov enzymes tshwj xeeb hauv txoj hauv kev.

Cov enzymes twg siv hauv photosynthesis?

Hauv Calvin lub voj voog, ATP thiab NADPH yog siv txo, lossis kho, carbon dioxide los tsim cov piam thaj. Qhov no carbon fixation cov tshuaj tiv thaiv yog catalyzed los ntawm ib tug enzyme hu ua RUBISCO, muaj protein ntau ntau hauv cov nroj tsuag thiab tej zaum yog cov protein ntau tshaj plaws hauv ntiaj teb.
