Roba metabolism, da asalinta da kuma rawa a cikin jiki

Roba metabolism wani sunan anabolism ko assimilation, kuma shi ne mai tarin dukan enzymatic biochemical halayen da haifar da bioorganic mahadi an hada.

Roba musayar hada da biosynthesis sunadarai, lipids, carbohydrates, nucleic acid. Lokacin da anabolism ma wuce aiwatar da photosynthesis da chemosynthesis.

Idan muka magana game da roba metabolism a cikin jikin mutum, shi wajibi ne a ce a lokaci daya da cewa duk da na gina jiki da cewa shigar da jiki da abinci, da wani babban kwayoyin abun da ke ciki, don haka ba za su iya ba za a assimilated. A kan aiwatar da narkewa, wadannan mahadi fada cikin mutum monomers, wanda aka riga amfani ga kira na musamman macromolecular abubuwa muhimmi a cikin jikin mutum.

Daya daga cikin mafi muhimmanci azuzuwan na mahadi sunadaran. Protein yanayi da duk enzymes daga cikin jiki, kazalika da wasu hormones. Sunadaran suna haemoglobin (samar da numfashi aiki), antibodies (rigakafi martani samar da kwayoyin), actin da myosin (predetermine tsoka ƙanƙancewa), collagen da keratin (yi da wani tsarin aiki a cikin jiki).

Ganin muhimmiyar rawa na gina jiki ga jiki zuwa aiki, wajibi ne a yi la'akari da aiwatar da su kira a matsayin wani muhimmin ɓangare na roba musayar.

Dole ne in ce cewa duk rayayyun kwayoyin halitta suka sãɓã wa jũna a gaban takamaiman sunadaran, wanda ake hada amino acid. Shi ne da dangi matsayi na amino acid da kayyade musamman Properties na gina jiki mahadi.

Sunadaran suna hada a cikin cell cytoplasm a musamman da wasu gabbansa - ribosomes. Wadannan Tsarin kunshi manyan da kananan subunits. Suna da hannu a gina jiki kira. An muhimmiyar rawa a cikin biosynthesis sunadaran wasa nucleic acid, wanda sun hada da DNA da RNA. Saboda haka, tsarin raka'a DNA (genes) ya žunshi masu lamba bayanai game da farko tsarin da sunadaran (amino acid jerin), da kuma RNA ne alhakin karatu da kuma ta sufuri zuwa shafin na amino acid, inda a can ne gina jiki kira.

Gina jiki kira na faruwa a matakai biyu: kwafi da kuma fassara. A core na kwafi ne tsari na canja wurin bayanai game da tsarin da gina jiki to DNA to RNA.

Translation - ne kai tsaye kira na a polypeptide sarkar da wani daidai da amino acid jerin bisa ga kwayoyin code, tare da taimako na wani matrix (bayanai) RNA. A dukan tsari na translation ke ta uku, saukarwa: qaddamarwa, elongation, terminanatsii. A sakamakon watsa labarai kafa gina jiki da primary tsarin.

Yana da daraja ambaton cewa musayar daga cikin roba - shi ne ba kawai da kira sunadarai ko wasu kwayoyin mahadi, amma photosynthesis, wanda shi ne mai hadaddun da multistage tsari, shi wuce a biyu bulan.

The haske lokaci gudana a chloroplast (a kan thylakoids), a cikinsa ATP da aka kafa da kuma secreted kwayoyin sunadarin oxygen da kuma duhu lokaci kara kullum chloroplast abu kuma Yanã shigar da sha na carbon dioxide da kuma samuwar carbohydrates.

Ina bukatan ba su zauna a kan rawar da photosynthesis, isar da shi a ce, godiya ga wannan tsari a shekara samar game da 150 biliyan. M abubuwa da kwayoyin halitta, kazalika kamar 200 biliyan. T oxygen.

Dole ne in ce cewa roba metabolism aka nasaba, makamashi matakai da faruwa a cikin jiki. Saboda haka, makamashi metabolism (catabolism) ne wani m aiwatar da anabolism da ya hada da duka da tsakiyan nonon dauki, a lokacin da hadaddun mahadi decompose zuwa sauki da kuma high-kwayoyin abubuwa suna tuba a cikin jerin low kwayoyin nauyi. Lokacin da wannan makamashi da aka saki, wadda aka yi amfani da roba metabolism tafiyar matakai.

Saboda haka, roba da kuma samar da makamashi metabolism a Kwayoyin samar da tushen daga cikin jimlar musayar - metabolism, wanda qunshi duk matakai na kira da kuma bazuwar daga abubuwa.
