Lub cev qhuav dej synthesis yog txheej txheem ntawm kev koom nrog ob lub molecules, los yog cov tebchaw, ua ke tom qab tshem tawm cov dej. Thaum lub sij hawm ib tug condensation cov tshuaj tiv thaiv, ob lub molecules yog condensed thiab dej ploj mus tsim ib tug loj molecule. Qhov no yog tib yam txheej txheem uas tshwm sim thaum lub sij hawm ib lub cev qhuav dej synthesis.
Tib neeg kuj nug, qhov tshwm sim ntawm lub cev qhuav dej yog dab tsi?
Hauv chemistry, a lub cev qhuav dej yog tshuaj tshuaj tiv thaiv uas cuam tshuam qhov poob ntawm cov dej molecule los ntawm cov reactant. Muaj lwm hom tshuaj tiv thaiv , hu ua condensation tshuaj tiv thaiv , uas yog txhais tau dav dua li a tshuaj tiv thaiv uas tshwm sim nyob rau hauv poob ntawm ib tug dej molecule.
Tsis tas li ntawd, vim li cas lub cev qhuav dej synthesis tseem ceeb? Lub cev qhuav dej synthesis yog tseem ceeb vim nws yog cov txheej txheem uas ntau cov organic polymers tau ua.
Tsis tas li ntawd, dab tsi yog qhov piv txwv ntawm lub cev qhuav dej synthesis?
Lwm cov piv txwv ntawm lub cev qhuav dej synthesis tshwm sim yog tsim ntawm triglycerides los ntawm fatty acids thiab tsim ntawm glycosidic bonds ntawm carbohydrate molecules, xws li tsim maltose los ntawm ob. qabzib molecules.
Dab tsi yog lub cev qhuav dej synthesis thiab hydrolysis?
Qhov txawv ntawm Lub cev qhuav dej synthesis thiab hydrolysis yog hais tias nyob rau hauv ib tug, bonds raug tsim, thaum nyob rau hauv lwm yam bonds raug puas tsuaj. Lub cev qhuav dej synthesis bonds molecules ua ke los ntawm kev tshem dej. Hauv hydrolysis , dej yog ntxiv rau cov molecules thiaj li yaj cov bonds.

Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Dab tsi tshwm sim ntawm Theodor Engelmann qhov kev sim nto moo qhia rau nws uas wavelength S yog tus tsav tsheb zoo tshaj plaws ntawm photosynthesis?
Cov kab mob sib sau ua ke ntau tshaj plaws nyob ze ntawm ib feem ntawm cov alga uas tau nthuav tawm cov xim liab thiab xiav wavelengths. Engelmann qhov kev sim ua kom pom tias lub teeb liab thiab xiav yog lub zog zoo tshaj plaws rau photosynthesis
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
Thawj kauj ruam ntawm cov protein synthesis yog dab tsi thiab nws tshwm sim qhov twg?
Thawj kauj ruam ntawm protein synthesis hu ua Transcription. Nws tshwm sim nyob rau hauv lub nucleus. Thaum lub sijhawm sau ntawv, mRNA luam tawm (daim ntawv theej) DNA, DNA yog 'unzipped' thiab mRNA strand luam ib strand ntawm DNA. Thaum nws ua li no, mRNA tawm ntawm lub nucleus thiab nkag mus rau hauv cytoplasm, mRNA yuav txuas nws tus kheej mus rau ribosome
