Mibvunzo Yemuenzaniso Pakukurukurirana kwePhotosynthesis
Photosynthesis inzira yebiochemical inoitwa nezvirimwa, algae, uye mamwe mabhakitiriya kushandura simba rezuva kuita simba remakemikari muchimiro cheglucose. Maitiro aya akakosha kuhupenyu hwePasi nekuti anogadzira okisijeni uye anoumba hwaro hwecheni yechikafu. Muchinyorwa chino, tichakurukura mienzaniso yakati wandei yematambudziko ane chekuita nephotosynthesis netsananguro dzawo kuti tikubatsire kunzwisisa pfungwa iyi.
Nhanganyaya kuPhotosynthesis
Tisati tapinda mumatambudziko emuenzaniso, zvakakosha kunzwisisa zvakakosha zve photosynthesis. Photosynthesis inoitika muma chloroplasts, ma organelles anowanikwa mumasero emiti. Maitiro aya anosanganisira matanho maviri makuru: reaction yechiedza uye Calvin cycle. Maaction echiedza anoitika mu thylakoid membrane, achishandisa chiedza kupatsanura mamorekuru emvura uye kugadzira ATP neNADPH. Calvin cycle, kune rumwe rutivi, inoitika mu chloroplast stroma, uko ATP neNADPH zvinoshandiswa kushandura carbon dioxide kuita glucose.
Mibvunzo yemuenzaniso nekukurukurirana
Mubvunzo 1: Maitiro Ekupatsanura Mvura
Mubvunzo:
Chii chinoitika panguva yekupatsanura mamorekuru emvura mu photosynthesis, uye izvi zvinoitika kupi?
Kukurukurirana:
Kupatsanurana kwemvura, kana kuti photolysis, inzira iyo mamorekuru emvura anopatsanurwa kuita okisijeni, mapurotoni, nemaerekitironi. Kuita uku kunoitika muthylakoids yema chloroplast panguva yekuchinja kwechiedza. Photolysis yakakosha nekuti maerekitironi akasunungurwa anoshandiswa muketani yekufambisa maerekitironi kuumba ATP neNADPH, uye okisijeni inoburitswa sechinhu chinobatsira pakurarama.
Mubvunzo 2: Pigments dzePhotosynthetic
Mubvunzo:
Tsanangura basa rechlorophyll mu photosynthesis uye nei zvirimwa zvichiita sezvine ruvara rwegirini?
Kukurukurirana:
Chlorophyll ndiyo pigment huru inopinza chiedza panguva ye photosynthesis. Kune mhando mbiri huru dze chlorophyll: chlorophyll a ne chlorophyll b. Pigments idzi dzinopinza chiedza chitsvuku nebhuruu-violet asi dzinoratidza girini, ndosaka zvirimwa zvichiita segirini. Chlorophyll yakakosha pakushandura simba rechiedza kuita simba remakemikari muchimiro cheATP neNADPH kuburikidza neketani yekufambisa maerekitironi.
Mubvunzo 3: Kutenderera kwaCalvin
Mubvunzo:
Chii chinoguma chaitika mushure mekutenderera kwaCalvin, uye molekile iyi inogadzirwa sei?
Kukurukurirana:
Chibereko chekupedzisira cheCalvin cycle iglucose, kunyange hazvo molekyuru inogadzirwa iri glyceraldehyde-3-phosphate (G3P). Kutenderera uku kunotanga nekusunga kabhoni dioxide neribulose-1,5-bisphosphate (RuBP), iyo inosanganisirwa neenzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). G3P inoshandiswa munzira dzakasiyana-siyana dzekugadzirisa glucose nemamwe makabhohaidhiretsi.
Mubvunzo 4: Zvinhu Zvakatipoteredza
Mubvunzo:
Dudza uye tsanangura zvinhu zvitatu zvakatipoteredza zvinopesvedzera mwero we photosynthesis.
Kukurukurirana:
1. Kusimba Kwechiedza: Photosynthesis inoda chiedza kuti chitungamirire mashandiro echiedza. Pakusimba kwechiedza kushoma, kumhanya kwephotosynthesis kunowedzera nekusimba kwechiedza kunowedzera. Zvisinei, pane imwe nguva, kumhanya kwephotosynthesis kunomira kuwedzera kunyangwe kusimba kwechiedza kuchiwedzera nekuda kwezvimwe zvinhu zvinokudzivisa.
2. Kuwanda kweCarbon Dioxide: Carbon dioxide ndiyo inonyanya kushandiswa muCalvin cycle. Kuwedzera huwandu hweCO2 kunogona kuwedzera mwero wephotosynthesis kusvika pane imwe nguva, mushure mezvo enzyme RuBisCO inova chinhu chinogumira.
3. Tembiricha: Tembiricha inokanganisa mashandiro ema enzyme, kusanganisira ayo anobatanidzwa mu photosynthesis. Mwero we photosynthesis unowanzo kuwedzera nekupisa kusvika panzvimbo yakanaka; kupfuura apa, mwero unoderera sezvo ma enzymes achipera.
Mubvunzo 5: Kufema Mufananidzo
Mubvunzo:
Chii chinorehwa nekufema nemufananidzo uye maitiro aya anokanganisa sei mhedzisiro yefotosinthsi?
Kukurukurirana:
Kufema nechiedza (Photorespiration) inzira inoshandiswa neRuBisCO okisijeni kuti iokisijeni yeRuBP, ichigadzira phosphoglycolate, iyo inozoshandurwa kuita glycate mu photorespiration cycle. Maitiro aya anoderedza kushanda kwe photosynthesis nekurasikirwa nekabhoni nesimba raigona kushandiswa kugadzira glucose. Kufema nechiedza (Photorespiration) kunowanzoitika kana paine chiedza chakawanda uye huwandu hweCO2 hwakaderera.
Penutup
Kunzwisisa photosynthesis kwakakosha nekuti maitiro aya akakosha kuhupenyu hwepanyika. Nekukurukura matambudziko akasiyana-siyana ane chekuita ne photosynthesis, tinogona kunzwisisa zvakadzama mashandiro ayo nezvinhu zvinoipesvedzera. Maitiro aya haasi ekungokosha chete kuzvinhu zvipenyu zvezvirimwa asiwo ane basa guru muzvinhu zvipenyu zvepasi rose uye kutenderera kwekabhoni. Tinovimba kuti matambudziko aya achakubatsira kunzwisisa zviri nani pfungwa ye photosynthesis.
