Muenzaniso weMibvunzo yeKukurukurirana yeZvifambiso Zvisina Kushandiswa
Kutakurwa kusingafambi (passive transport) inzira yakakosha yekufambisa mamorekuru kana maion kuburikidza nemasero pasina kushandisa simba kubva kuATP (adenosine triphosphate). Kutakurwa uku kunoshandisa musiyano wekuwanda kwezvinhu pakati pemativi maviri emembrane, zvichibvumira zvinhu kufamba kubva pakakwirira kusvika pakaderera. Muchinyorwa chino, tichakurukura nezvekutakura kusingafambi zvakadzama uye tichapa mienzaniso yakati wandei yezvinetso kutibatsira kunzwisisa maitiro aya.
1. Tsanangudzo yeKutakura Kusina Kushanda
Kutakurwa kusingafambi (Passive transport) kufamba kwemamorekuru kana maion kuburikidza nemembrane yesero pasina kushandisa simba. Maitiro aya anoenderana nekuwedzera kwehuwandu hwezvinhu, musiyano wehuwandu hwezvinhu mukati nekunze kwesero. Kune mhando dzakasiyana dzekutakura kusingafambi: kupararira kuri nyore, kupararira kuri nyore, osmosis, uye kusefa.
– Kupararira Zviri Nyore: Mamorekuru anofamba zvakananga nepakati pemafuta maviri emembrane pasina rubatsiro rwemapuroteni. Muenzaniso wekufamba kwemagasi akadai seokisijeni nekabhoni dioxide.
– Kupararira Kunobatsira: Mamorekuru anofamba nepakati peganda achibatsirwa nemapuroteni emugero kana anotakura. Mamorekuru makuru kana epolar, akadai seglucose, anowanzoda kupararira kuri nyore.
– Osmosis: Yakagadzirirwa kufamba kwemvura nepa membrane inopindika zvishoma kubva mumushonga une huwandu hwakaderera kusvika pahuwandu hwakawanda hwezvinhu zvakanyungudutswa.
2. Mibvunzo yemuenzaniso nekukurukurirana
Inotevera mimwe mienzaniso yemibvunzo ine chekuita nekufambisa zvinhu zvisina basa pamwe chete nehurukuro dzekusimbisa kunzwisisa pfungwa iyi.
Mubvunzo 1: Kupararira Kuri Nyore
Sero dzvuku reropa rinoiswa mu hypotonic solution. Chii chinoitika kusero dzvuku reropa?
Kukurukurirana:
Mumushonga we hypotonic, huwandu hwe solute kunze kwesero hunenge hwakaderera pane huri mukati. Nekuda kweizvozvo, mvura inopinda mumasero matsvuku eropa kuburikidza ne osmosis. Mvura painopinda, masero matsvuku eropa anozvimba uye anogona kuputika kana mvura yakawandisa ikapinda.
Mubvunzo 2: Kuparadzirwa Kwakareruka
Glucose inofanira kupinda mumasero kuburikidza nekufambisa kusingafambi. Zvisinei, haigone kuyambuka membrane yesero zvakananga. Tsanangura kuti glucose inopinda sei mumasero.
Kukurukurirana:
Glucose imorekuru hombe, ine polar. Saka, haigone kuyambuka membrane yesero nekungopararira nyore nyore. Mukupararira kuri nyore, glucose inopinda musero nerubatsiro rwemapuroteni anotakura glucose chaiwo. Mapuroteni aya anobatsira glucose kuyambuka membrane pasina kuda simba, nekushandisa gradient yakakwira yeglucose iri kunze kwesero zvichienzaniswa neiri mukati.
Mubvunzo 3: Osmosis
Kana chirimwa chikaiswa mumushonga une hypertonic, chichava nemigumisiro yei pamasero echirimwa?
Kukurukurirana:
Mumhinduro ine hypertonic, huwandu hwezvinhu zvinonyungudutsa kunze kwesero hwakakwira kupfuura huri mukati. Mvura inobuda musero remuti kuburikidza ne osmosis, zvichiita kuti sero rirasikirwe ne turgor uye riderere. Nekuda kweizvozvo, sero remuti rinoitwa plasmolysis, uko plasma membrane inobuda pamadziro esero nekuda kwekuderera kweprotoplasm.
Mubvunzo 4: Kusefa
Nzira yekusefa yakasiyana sei nedzimwe mhando dzekutakura dzisingashande?
Kukurukurirana:
Kusefa inzira iyo mamorekuru anofamba nepakati peganda zvichibva pakumanikidzwa kwehydrostatic. Kusiyana nekupararira kana osmosis, iyo inotsamira pakuyera kwehuwandu, kusefa kunoenderana nekusiyana kwekumanikidzwa, senge kunoitika muitsvo kana ropa richisefa.
3. Mashandisirwo ePassive Transport muhupenyu hwezuva nezuva
Kunzwisisa mafambiro asingashande kune zvakunobatsira muminda yakaita semishonga nesainzi yezvakatipoteredza. Semuenzaniso, dialysis yeitsvo, iyo inoshandisa kupararira uye osmosis kubvisa tsvina kubva muropa, inopa nzira yakakosha yehupenyu kune varwere vane dambudziko reitsvo. Saizvozvowo, kuchengetedzwa kwechikafu kuburikidza ne osmosis nekushandisa shuga yakawanda kana munyu kubudisa mvura kubva mumasero ehutachiona uye kudzivirira kukura kwawo ndeimwe nzira inoshanda.
4. Kuenzanisa neActive Transport
Kutakurwa kusingafambi kwakasiyana zvikuru nekutakurwa kunoshanda. Kutakurwa kunoshanda kunoda simba kuti zvinhu zvifambiswe zvichienderana nehukuru hwehuwandu. Izvi zvakakosha mumamiriro ezvinhu apo masero anofanira kutora zvinhu kubva munzvimbo ine huwandu hwakaderera pane huri mukati mesero, zvakaita sekutorwa kwemaion kuburikidza nemapombi eion, senge pombi yesodium-potassium.
5. Mhedziso
Kutakurwa kusingafambi kunoita basa rakakosha muhupenyu hwemasero, zvichibvumira mamorekuru nemaion kuchengetedza kuenzana pasina kuda simba rakawedzerwa. Nekunzwisisa kupararira kuri nyore, kupararira kuri nyore, osmosis, uye kusefa, tinogona kunzwisisa zviri nani mabasa ekutanga emasero mukuchengetedza homeostasis uye mabasa awo ehupenyu.
Kuburikidza nemienzaniso yakasiyana-siyana yakurukurwa, tinotarisirwa kukwanisa kushandisa pfungwa dzekutakura zvinhu zvisina kufambiswa zvakanaka mumamiriro ezvinhu akafara, kusanganisira zvinorehwa muhupenyu hwezuva nezuva uye minda yesainzi yakakodzera. Kunzwisisa kwakakwana nzira dzekutakura zvinhu zvisina kufambiswa zvakanaka kwakakosha kwete chete kuvadzidzi vanodzidza biology asiwo kune nyanzvi dzesainzi yehutano nezvakatipoteredza dzinogara dzichishandisa pfungwa idzi mubasa radzo.
