Feem ntau cov roj ntsha molecules loj heev thiab tsim los ntawm kev sib sau ua ke me me, los yog cov monomers , ua chains ntev . A txheej txheem ntawm kev sib txuas monomers , hu ua dehydration condensation, suav nrog kev tshem tawm ob lub hydrogen atoms thiab ib qho oxygen atom rau daim ntawv dej.
Ntawm no, yog tau los ntawm kev ntxiv monomers ua ke los tsim cov saw ntev?
Nws yog qee zaum ua tau, tshwj xeeb tshaj yog nyob rau hauv thaj tsam ntawm cov organic chemistry, koom nrog cov molecules me ua ke los tsim cov saw ntev . Lub sij hawm rau lub chains ntev yog polymer thiab cov txheej txheem hu ua polymerization. Poly- txhais tau tias ntau, whereas -mer txhais tau tias chav tsev. Muaj ntau units sib xyaw ua ke ib tug tshiab, ib chav tsev.
Tsis tas li ntawd, dab tsi yog txheej txheem hu ua macromolecules tsim? Macromolecules los yog polymers, yog tsim los ntawm kev sib xyaw ua ke ntawm cov molecules me me los yog monomers nyob rau hauv ib theem zuj zus. Qhov no yog lub zog xav tau txheej txheem hu ua polymerization uas tsim cov dej raws li ib tug byproduct. Piv txwv ntawm cov macromolecules suav nrog nucleic acids, lipids, proteins thiab carbohydrates.
Ib yam li ntawd, monomers koom ua ke li cas?
Cov cov monomers ua ke nrog ib leeg ntawm covalent bonds los tsim cov molecules loj dua hu ua polymers. Ua li ntawd, cov monomers tso dej molecules ua byproducts. Yog li ntawd, lub cov monomers uas yog koom ua ke yog dehydrated kom tso cai rau synthesis ntawm ib tug loj molecule.
Cov monomers twg tau muab tso ua ke los tsim cov enzymes?
Enzymes sib cais los yog muab tso ua ke molecules. Dab tsi yog cov enzymes ua los ntawm thiab ua li cas cov duab ntawm ib qho enzyme cuam tshuam rau nws txoj haujlwm? Lawv yog tsim los ntawm cov proteins.

Cov txheej txheem ntawm kev tsim cov kev daws teeb meem yog dab tsi?
Kev daws yog tsim thaum ib yam khoom hu ua thesolute 'dissolves' rau hauv lwm yam khoom hu ua hnyav.Dissolving yog thaum lub solute tawg los ntawm ib tug loj siv lead ua ntawm molecules mus rau ntau me me los yog ib tug molecules. Lawv ua qhov no los ntawm rub tawm cov ions thiab tom qab ntawd ncig cov ntsev molecules
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
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog lub luag haujlwm ntawm ATP hauv kev sib txuas lus sib txuas?
ATP coupling tso cai rau cov tshuaj tiv thaiv uas xav tau lub zog tshwm sim los ntawm kev siv lub zog tso tawm hauv kev hloov pauv ntawm ATP mus rau ADP kom lub zog tas li ntawm cov tshuaj tiv thaiv
Dab tsi ntawm cov khoom sib txuas sib txuas muaj nyob ntawm cov dej molecules?
Piv txwv li, dej molecules yog tuav ua ke los ntawm hydrogen bonds ntawm hydrogen atom ntawm ib lub molecule thiab cov pa atom ntawm lwm tus (daim duab: hydrogen bonds). Hydrogen bonds yog ib qho muaj zog intermolecular quab yuam thiab muaj zog dua lwm cov dipole-dipole rog
