Catabolic tshuaj tiv thaiv tawg nqes loj organic molecules rau hauv me me molecules , tso lub zog uas muaj hauv chemical bonds.
Tom qab ntawd, ib tus tuaj yeem nug, hom tshuaj tiv thaiv twg tshwm sim thaum cov molecules loj tawg ua cov me?
Anabolism thiab catabolism Ob hom ntawm metabolic cov tshuaj tiv thaiv coj qhov chaw hauv lub cell: 'lub tsev nce ' (anabolism) thiab ' tawg ' (catabolism). Catabolic cov tshuaj tiv thaiv muab lub zog. Lawv yog exergonic. Hauv ib catabolic cov tshuaj tiv thaiv loj molecules tau tawg mus rau hauv cov me me.
Ib yam li ntawd, hom tshuaj tiv thaiv dab tsi cuam tshuam nrog kev tawg ntawm cov molecules loj? Catabolism yog cov tshuaj tiv thaiv kab mob uas rhuav tshem cov molecules loj. Lub zog tau tso tawm txoj kev no, qee qhov nws tuaj yeem siv rau anabolism. Cov khoom ntawm catabolism tuaj yeem rov ua dua los ntawm cov txheej txheem anabolic rau hauv cov tshiab anabolic molecules.
Kuj Paub, dab tsi yog txheej txheem ntawm kev rhuav tshem cov molecules loj rau hauv cov me?
Catabolism yog txheej txheem ntawm kev tawg qee loj molecules rau hauv me me uas lub cev siv tau. Piv txwv li, thaum ib tug neeg noj cov zaub mov uas muaj protein ntau, lub cev tawg cov no nqes los ntawm catabolism rau hauv amino acids.
Thaum twg ib tug loj molecule tawg mus rau hauv me me molecules los ntawm ntxiv dej no hom tshuaj tiv thaiv tau tshwm sim?
Hydrolysis. Polymers yog tawg rau hauv cov monomers hauv txheej txheem hu ua hydrolysis, uas txhais tau tias rau cais dej ,”ua tshuaj tiv thaiv hauv koj a dej molecule yog siv thaum lub sij hawm tawg. Thaum lub sij hawm no cov tshuaj tiv thaiv , yog polymer tawg rau hauv ob yam.

Qhov twg ntawm cov tshuaj tiv thaiv kab mob ua rau cov ntawv cog lus tawg?
Lub zog ua kom muaj zog yog lub zog uas yuav tsum tau nqus kom muaj tshuaj lom neeg pib. Thaum lub zog ua kom txaus ntxiv rau cov reactants, cov ntawv cog lus hauv cov reactants tawg thiab cov tshuaj tiv thaiv pib
Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Hom tshuaj twg pom nyob rau hauv cov khoom ntawm cov tshuaj tiv thaiv decomposition?
Cov tshuaj tiv thaiv decomposition tshwm sim thaum ib qho reactant tawg mus rau hauv ob lossis ntau yam khoom. Qhov no tuaj yeem sawv cev los ntawm kev sib npaug dav: AB → A + B. Cov piv txwv ntawm cov tshuaj tiv thaiv decomposition muaj xws li kev tawg ntawm hydrogen peroxide rau dej thiab oxygen, thiab kev tawg ntawm cov dej mus rau hydrogen thiab oxygen
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
