Muaj ob hom dav dav cov txheej txheem metabolic : catabolic thiab anabolic. Catabolic txoj kev tso tawm lub zog thaum rhuav tshem cov molecules rau hauv cov molecules yooj yim dua. Cellular ua pa yog ib qho piv txwv ntawm catabolic txoj kev . Cov txheej txheem ntawm glycolysis yog siv los tsim lub zog ntawm catabolic txoj kev.
Tsuas yog li ntawd, koj txhais li cas los ntawm txoj kev biochemical?
Biochemical txoj kev revolve nyob ib ncig ntawm ib txheej ntawm enzymes uas ua rau series ntawm cov tshuaj tiv thaiv ua tau ntawm cov kab mob lom. Piv txwv li: Kev rhuav tshem cov piam thaj mus rau pyruvate, hauv lub cell, tsim ATP los ntawm ntau cov tshuaj tiv thaiv nrog kev pab ntawm enzymes, biochemical txoj kev.
Tom qab ntawd, lo lus nug yog, dab tsi yog qee qhov piv txwv ntawm biochemistry? Muaj plaub chav kawm ntawm biochemical cov khoom xyaw: carbohydrates, proteins, lipids (rog), thiab nucleic acids. Peb tau txais cov no los ntawm peb cov khoom noj. Carbohydrates yog molecules tsim los ntawm carbon, oxygen, thiab hydrogen.
Tib neeg kuj nug, qhov piv txwv ntawm txoj kev metabolic yog dab tsi?
Ib qho zoo piv txwv ntawm txoj kev metabolic yuav yog qhov sib npaug ntawm kev ua pa ntawm tes uas cov piam thaj tau oxidized los ntawm oxygen los tsim ATP, adenosine triphosphate. ATP molecule yog siv los ntawm tag nrho cov tsiaj hlwb ua lub zog tseem ceeb rau lub hlwb ua haujlwm.
Yuav ua li cas yog ib tug biochemical quizlet?
A metabolic cov tshuaj tiv thaiv uas xav tau lub zog los tsim lub zog rau lub cell. Ib yam kab mob uas ua rau nws tus kheej cov khoom noj los ntawm lub teeb lossis tshuaj lom neeg lub zog. Biochemical Txoj Kev . Cov tshuaj tiv thaiv nyob rau hauv ib lub cell uas muaj nyob rau hauv ib tug series ntawm intermediate tebchaw (los yog cov kauj ruam) mus rau qhov kawg khoom.

Ib qho piv txwv ntawm kev sib txawv ntawm tes yog dab tsi?
Cov txheej txheem thiab cov kauj ruam ntawm Cell Differentiation Ib lub xovtooj ntawm tes muaj peev xwm sib txawv rau txhua hom cell hu ua 'totipotent'. Piv txwv ntawm cov qia thiab progenitor hlwb muaj xws li: Hematopoietic Stem Cells - Cov no yog los ntawm cov pob txha pob txha thiab koom nrog hauv kev tsim cov qe ntshav liab thiab dawb nrog rau cov platelets
Ib qho piv txwv ntawm ib qho alloy yog dab tsi?
Ib qho piv txwv ntawm cov hlau yog sib xyaw ntawm cov hlau thiab hlau. Ib qho piv txwv ntawm cov hlau yog cov tin hauv qhov sib xyaw ntawm tooj liab thiab tin uas ua rau tooj liab. Lub alloy yog ib qho fusion ntawm ob lossis ntau dua hlau lossis cov hlau uas tsis yog hlau. Ib qho piv txwv ntawm cov hlau yog tooj dag, uas yog tsim los ntawm tooj liab thiab zinc
Ib qho piv txwv ntawm kev xav hauv kev tshawb fawb yog dab tsi?
Piv txwv ntawm kev tshawb xav txog kev tshawb fawb yog: Issac Newton's "System of the World" uas yog thawj qhov kev xav hauv lub ntsiab ntawm physics. Einstein's Special Relativity thiab General Relativity. Darwin's Theory of Evolution by Natural Selection. Thermodynamics, txoj kev xav uas suav nrog plaub txoj cai ntawm Thermodynamics
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
