Nrog plaub electronegative oxygen atoms, phosphate pawg yog heev reactive, thiab hloov ntawm a phosphate pawg los ntawm ib lub molecule mus rau lwm tus muab lub zog rau cov tshuaj tiv thaiv. ATP, lub luag haujlwm tseem ceeb hauv lub hlwb, yog tsim los ntawm peb phosphate pawg sib koom ua ke.
Hauv qhov no, dab tsi yog qhov tseem ceeb ntawm txhua lub hlwb?
Cov kab mob uas ua rau lawv tus kheej noj. Cov kab mob uas nyob ntawm lwm yam kab mob rau lawv lub zog. Dab tsi yog qhov qhov tseem ceeb ntawm txhua lub hlwb ? Zog yog lub kev xav tau tseem ceeb.
Ib yam li ntawd, qhov twg ntawm cov pab pawg ua haujlwm tau qhia saum toj no feem ntau yuav? Qhov twg ntawm cov pab pawg ua haujlwm tau qhia saum toj no feem ntau yuav mus nce ib tug proton thiab ua zoo them? Cov amino pawg feem ntau yuav kom tau ib tug proton. Ib pawg amino ua lub hauv paus thiab tuaj yeem khaws cov protons los ntawm ib puag ncig nruab nrab, ua kom zoo.
Tsuas yog li ntawd, vim li cas cov pab pawg ua haujlwm tseem ceeb rau cov molecules?
Cov pab pawg ua haujlwm yog tseem ceeb hauv chemistry vim lawv yog ib feem ntawm a molecule uas muaj peev xwm ntawm cov yam ntxwv tshwm sim. Lawv, yog li ntawd, txiav txim siab cov khoom thiab chemistry ntawm ntau cov organic tebchaw.
ATP qhov tseem ceeb hauv lub cell yog dab tsi?
Cov tshuaj Adenosine triphosphate ( ATP ) molecule yog cov nucleotide paub nyob rau hauv biochemistry li "molecular txiaj" ntawm intracellular zog hloov; uas yog, ATP muaj peev xwm khaws thiab thauj cov tshuaj lom neeg lub zog hauv hlwb . ATP kuj plays ib tseem ceeb lub luag haujlwm hauv kev tsim cov nucleic acids.

Lub koom haum loj yog dab tsi, los ntawm qhov tsawg tshaj plaws mus rau qhov loj, uas cov kws tshawb fawb feem ntau kawm? 6 theem sib txawv ntawm lub koom haum uas ecologists nquag kawm yog hom, pejxeem, zej zog, ecosystem, thiab biome
Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Dab tsi feem ntau yog pab pawg ua haujlwm thiab vim li cas cov pab pawg no tseem ceeb?
Cov pab pawg ua haujlwm tau txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj ntseg dua li cov pa roj carbon monoxide thiab zoo li yuav koom nrog cov tshuaj tiv thaiv
Avery thiab nws pab pawg tau txiav txim siab li cas molecule tseem ceeb tshaj plaws rau kev hloov pauv?
Qhia luv luv hais tias Avery thiab nws pab pawg tau txiav txim siab tias qhov twg yog qhov tseem ceeb tshaj plaws rau kev hloov pauv. Avery thiab nws pab pawg tau siv ob lub enzymes sib txawv ntawm cov kab mob tua hluav taws kub. Ib qho rhuav tshem DNA, lwm qhov rhuav tshem txhua yam tab sis. Lawv pom tias kev hloov pauv tseem tshwm sim thaum DNA nyob
Dab tsi ntawm lub voj voog ntawm tes yog qhov tseem ceeb tshaj plaws?
Ua ke, G1, S, thiab G2 theem ua rau lub sijhawm hu ua interphase. Cells feem ntau siv sij hawm ntau nyob rau hauv interphase dua li lawv ua hauv mitosis. Ntawm plaub theem, G1 yog qhov sib txawv tshaj plaws ntawm lub sijhawm, txawm hais tias nws feem ntau yog qhov ntev tshaj plaws ntawm lub voj voog ntawm tes (Daim duab 1)
