Ib ntawm txoj kev qhov no ATP khoom yog tsim dua tshiab yog los ntawm cov molecule creatine phosphate (lossis phosphocreatine). Hauv txheej txheem ntawm rov tsim dua tshiab ntawm ATP , creatine phosphate hloov pauv lub zog phosphate mus rau ADP. Cov khoom ntawm cov tshuaj tiv thaiv no yog ATP thiab creatine.
Ib qho ntxiv, cov peev txheej siv hluav taws xob los tsim ATP yog dab tsi?
Peb lub tswv yim rau Kev tsim kho ATP yog creatine phosphate, anaerobic glycolysis, thiab aerobic metabolism. Creatine phosphate muab txog thawj 15 vib nas this ntawm ATP thaum pib ntawm cov nqaij ntshiv. Anaerobic glycolysis ua rau me me ntawm ATP thaum tsis muaj oxygen rau lub sijhawm luv.
Tom qab ntawd, lo lus nug yog, yuav muaj dab tsi tshwm sim thaum tsis muaj ATP muaj rau kev cog lus? Hauv qhov tsis muaj ATP , lub taub hau myosin yuav tsis cais los ntawm actin. Ib feem ntawm myosin lub taub hau txuas rau qhov chaw khi ntawm actin, tab sis lub taub hau muaj lwm qhov chaw khi rau ATP . Tsuav yog ATP yog muaj , nws nkag tau yooj yim rau myosin, kev hla tus choj hla kev tuaj yeem rov tshwm sim, thiab leeg nqaij kev cog lus tuaj yeem txuas ntxiv.
Tom qab ntawd, lo lus nug yog, dab tsi txuas ntxiv ntawm ib kab Z mus rau tom ntej?
Cov Cuab Yeej Sib Cais hauv Cov leeg pob txha Cov leeg nqaij yog cov loj loj uas muaj ntau lub hlwb sib txuas uas nws pom tseeb tshaj plaws yog qhov sib txawv. Chav ua haujlwm ntawm kev cog lus yog sarcomere, uas txuas los ntawm ib Z -disk rau tom ntej no . Tag nrho cov ntsiab lus ntawm cov leeg yog xa lub zog rau sab nraud ntawm cov leeg.
Cov organelle twg muab ATP lub zog rau cov leeg sib zog?
Pob txha nqaij tau ua los ntawm cov cell ntev, nyias uas tau ntim nrog cov protein ntau thiab organelles . Thaum lub zog qoj ib ce, tus nqi ntawm zog siv hauv cev pob txha nqaij tuaj yeem nce ntau dua 100-fold yuav luag tam sim. Kom tau raws li qhov no zog xav tau, nqaij cov hlwb muaj mitochondria.

Dab tsi yog tus pab tsim nyog thawj pab?
Lub hauv paus pib yog txiav txim siab seb hom neeg pab neeg twg uas koj xav tau yog: tus neeg muaj peev xwm pab tau thawj zaug, lossis tsuas yog tus neeg saib xyuas lub thawv pab thawj zaug. Tus pab thawj zaug yog ib tus neeg uas tsim nyog muab kev kho mob thawj zaug thaum raug mob lossis mob
Dab tsi yog lub npe ntawm cov khoom tsim uas yog qhov tseem ceeb rau kev pib tsim cov ntshav khov?
Thrombocytes (platelets) Megakaryocytes tsim los ntawm hemocytoblasts hauv cov pob txha liab. Thrombocytes dhau los ua nplaum thiab sib sau ua ke los ua cov platelet ntsaws uas kaw qhov tawg thiab kua muag hauv cov hlab ntshav. Lawv kuj pib tsim cov ntshav txhaws
Dab tsi yog qhov laj thawj rau muab kev teeb tsa thib ob los ua kom rov tsim lub mis?
Dab tsi yog qhov laj thawj rau kev teeb tsa zaum thib ob los ua lub tsev kho lub mis tom qab hloov kho qhov mob mastectomy vim yog kev ua phem? Txhawm rau khaws cov qog nqaij hlav cancer kom deb ntawm cov cuab yeej uas yuav siv los tsim kho dua tshiab
Nyob rau theem dab tsi ntawm kev tsim cov kab mob fungal yog diploid cells tsim?
Hauv lub neej voj voog ntawm kev sib deev kis tus kab mob hu ua fungus, theem haploid hloov nrog qib diploid. The haploid theem xaus nrog nuclear fusion, thiab theem diploid pib nrog kev tsim zygote (diploid cell ua los ntawm fusion ntawm ob haploid cells)
Cov kab mob hauv qhov ncauj dab tsi metabolize sucrose tsim cov nplaum glucans thiab tsim cov quav hniav?
GTF yog qhov tseem ceeb enzyme uas catalyzes sucrose rau nplaum glucans thiab pab txhawb kev tsim cov hniav plaque nyob rau hauv uas lub tsub zuj zuj ntawm metabolic acids uas ua los ntawm cov kab mob colonies ua rau lub zos demineralization ntawm cov enamel nto (Loesche, 1986)
