Cov ob theem ntawm photosynthesis : Photosynthesis siv qhov chaw hauv ob theem: lub teeb-nyob ntawm cov tshuaj tiv thaiv thiab Calvin lub voj voog (lub teeb-yeeb yaj kiab). Lub teeb-dependent tshuaj tiv thaiv, uas coj qhov chaw nyob rau hauv thylakoid daim nyias nyias, siv lub teeb lub zog los ua ATP thiab NADPH.
Ib yam li ntawd, koj tuaj yeem nug, Phase 1 ntawm photosynthesis tshwm sim nyob qhov twg?
Theem Ib : Lub teeb Reactions Nyob rau hauv lub teeb-dependent txheej txheem, uas yuav siv sij hawm qhov chaw nyob rau hauv lub grana, lub stacked membrane qauv nyob rau hauv chloroplasts, lub zog ncaj qha ntawm lub teeb pab cov nroj tsuag ua molecules uas nqa lub zog rau kev siv nyob rau hauv qhov tsaus ntuj nti. theem ntawm photosynthesis.
Ib tug kuj yuav nug, dab tsi yog peb theem ntawm photosynthesis thiab lawv tshwm sim qhov twg? Nws yog qhov yooj yim los faib cov photosynthetic txheej txheem hauv cov nroj tsuag ua plaub theem , cwb tshwm sim nyob rau hauv ib cheeb tsam ntawm chloroplast: (1) nqus lub teeb, (2) electron thauj mus rau qhov txo ntawm NADP+ rau NADPH, ( 3 ) tiam ntawm ATP, thiab (4) kev hloov pauv ntawm CO2 nyob rau hauv carbohydrates (carbon fixation).
Ib sab ntawm no, qhov thib ob theem ntawm photosynthesis tshwm sim?
Cov theem ob ntawm photosynthesis tshwm sim nyob rau hauv lub stroma nyob ib ncig ntawm lub thylakoid daim nyias nyias ntawm chloroplast. Cov tshuaj tiv thaiv ntawm no theem tuaj yeem tshwm sim tsis muaj lub teeb, yog li lawv qee zaum hu ua lub teeb-yooj yim lossis tsaus ntuj.
Photosystem 1 thiab 2 nyob qhov twg?
Photosystems yog pom nyob rau hauv thylakoid daim nyias nyias ntawm cov nroj tsuag, algae thiab cyanobacteria. Lawv yog nyob nyob rau hauv chloroplasts ntawm cov nroj tsuag thiab algae, thiab nyob rau hauv lub cytoplasmic membrane ntawm photosynthetic kab mob. Muaj ob hom kev yees duab : II i.
Pom zoo:
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
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
Cov kauj ruam ntawm mitosis yog dab tsi thiab dab tsi tshwm sim hauv txhua qhov?
Mitosis muaj tsib theem sib txawv: interphase, prophase, metaphase, anaphase thiab telophase. Cov txheej txheem ntawm cell faib tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sij hawm anaphase thiab telophase. Txhua theem ntawm mitosis yog tsim nyog rau cell replication thiab faib
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
