Interphase yog tsim los ntawm G1 Phase (kev loj hlob ntawm tes), ua raws li S theem (DNA synthesis), ua raws li G2 Phase (kev loj hlob ntawm tes). Thaum kawg ntawm interphase los ntawm mitotic theem , uas yog tsim los ntawm mitosis thiab cytokinesis thiab ua rau kev tsim ntawm ob tug ntxhais hlwb.
Ua li no, ua li cas hauv g2 theem?
Gap 2 ( G2 ): Thaum lub sij hawm sib txawv ntawm DNA synthesis thiab mitosis, lub cell yuav loj hlob mus ntxiv thiab tsim cov proteins tshiab. Mitosis los yog M Theem : Kev loj hlob ntawm tes thiab kev tsim cov protein nres nyob rau theem no hauv lub voj voog ntawm tes.
Ib yam li ntawd, qhov txawv ntawm g1 thiab g2 theem yog dab tsi? Ib qho tseem ceeb qhov sib txawv ntawm kev loj hlob theem yog tias thawj qhov kev loj hlob theem yog hais txog kev loj hlob ntawm tes thaum G2 yog hais txog kev faib cell.
Khaws qhov no hauv kev txiav txim siab, dab tsi tshwm sim ntawm g1 theem?
G1 Phase . G1 yog ib qho nruab nrab theem tuav lub sijhawm ntawm qhov kawg ntawm kev faib cell hauv mitosis thiab pib ntawm DNA replication thaum S theem . Lub sijhawm no, lub cell loj hlob hauv kev npaj rau DNA replication, thiab qee yam khoom siv hauv lub cev, xws li cov centrosomes tau txais kev rov ua dua tshiab.
Puas organelles replicate hauv g1 lossis g2?
Nyob rau theem no, organelles yog luam tawm thiab cov proteins yog synthesized. Cov G2 theem ua raws DNA rov ua dua uas tshwm sim thaum lub sij hawm S-phase. Lub voj voog ntawm tes pib nrog lub sijhawm so hu ua G0, ua raws li cov G1 Phase, S thiab G2 cov theem uas hu ua interphase.
Pom zoo:
S sawv rau dab tsi thiab dab tsi tshwm sim hauv theem no?
S theem sawv rau 'Synthesis'. Qhov no yog theem thaum DNA replication tshwm sim. The G2 stage stands for 'GAP 2'
Ob theem tseem ceeb ntawm photosynthesis yog dab tsi thiab txhua theem tshwm sim nyob qhov twg?
Ob theem ntawm photosynthesis: Photosynthesis yuav siv sij hawm qhov chaw nyob rau hauv ob theem: lub teeb-dependent kev tshwm sim thiab lub Calvin voj voog (lub teeb-yooj yim kev xav). Lub teeb-nyob ntawm cov tshuaj tiv thaiv, uas tshwm sim hauv thylakoid daim nyias nyias, siv lub teeb lub zog los ua ATP thiab NADPH
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
4 theem ntawm cellular respiration yog dab tsi thiab lawv tshwm sim qhov twg?
Cov txheej txheem ua pa ntawm tes muaj xws li plaub theem lossis theem pib: Glycolysis, uas tshwm sim hauv txhua yam kab mob, prokaryotic thiab eukaryotic; tus choj cov tshuaj tiv thaiv, uas stets theem rau aerobic ua pa; thiab lub voj voog Krebs thiab cov saw hlau thauj hluav taws xob, txoj hauv kev nyob ntawm oxygen uas tshwm sim nyob rau hauv ib ntus
