Mubodilai modda dar organizmho

Hamai organizmhoi zinda qobiliyati mubodilai moddahoro bo muhiti beruna dorand. Onho moddahoi baroi gizo zarurro girifta, mahsuli faoliyati hayoti kheshro khorij mekunand.

obmen_vDar tabiati gayrizinda niz mubodilai moddaho vujud dorad. Vale dar gardishi gayribiologii modda onho az yak jo ba joi digar burda meshavand (masalan, hodisai eroziyai khok yo bodkhurdashavi, obshuyshavii zamin) yo holati agregatiashon tagiyr meyobad (masalan, tabdilyobii ob ba bug yo yakh).

Mubodilai moddaho dar tabiati zinda az tabiati gayrizinda farq mekunad. Dar gardishi moddahoi organiki joi muhimro ravandi tabdilyobii modda – jarayoni sintez va tajziya ishgol menamoyad.

Organizmhoi zinda az muhiti beruna moddahoi gizoiro furu mebarand. Dar natijai tabdilyobihoi murakkabi khimiyavi onho ba moddahoi organizmi zinda monand khohand shud. CHunin ravand assimilatsiya nom dorad.

Jonibi digari mubodilai moddaho ravandi dissimilyatsiya meboshad. Dar natijai dissimilyatsiya moddahoi murakkabi organiki ba moddahoi sodda tabdil yofta, shabohati onho ba moddahoi organizm az bayn meravad va energiyae khorij megardad, ki baroi reaksiyai biosintez zarur ast. Az hamin sabab, dissimilyatsiyaro mubodilai energetiki niz menomand.

Mubodilai moddaho gomeostazi organizmro tamin mesozad. Onho omili tagyirnopazirii sokhtori khimiyavi va hama qismathoi organizm meboshand. Mubodilai moddaho dar sharoiti beist tagyiryobandai muhiti beruna qobiliya-

ti hayoti va faoliyati organizmhoro tamin mekunad.
