Dissimilation - ichi ... Steps dissimilation

Dissimilation - kunzwisisa nemakemikari umo mune zvishoma nezvishoma manyowa kunzwisisa Organic yeimwe kuti nyore. Izvi achabatsirwa nokusunungurwa simba, zvikuru iyo inoshandiswa ATP usage.

Dissimilation mu zvipenyu

Dissimilation kwacho pakatarisana kuitwa. Sezvo kutanga zvinhu pasi kuora, kuita nucleic acids, mapuroteni, kwemafuta uye makabhohaidhiretsi. A yokupedzisira zvigadzirwa - mvura, carbon dioxide uye amoniya. The manyowa zvibereko muviri mhuka pamwe zvishoma nezvishoma kuwanda asunungurwa kuti kunze. Uye chirimwa carbon dioxide inobvisa asunungurwa omei uye zvakazara amoniya zvaishandiswa nedanho kuitwa, somurongi kutanga mashoko biosynthesis kuti makemikari yeimwe.

The ukama dissimilation uye kuitwa rinobvumira munyama muviri vari kuramba achiudza. Somuenzaniso, mazuva 10 ari sealbumin yoku- mumasero hafu yeropa revanhu, uye nokuda 4 months panoda erythrocytes zvose. kusimba reshiyo maviri akatarirana metabolic pezvakaitwa anoenderana zvinhu zvakawanda. Danho iri kutanga nhengo, uye zera uye vasiri mamiriro. Panguva kukura muviri kuitwa rikunde, zvichiita chimiro itsva masero, nyama uye nhengo ndiyo Kusiyanisa yavo, ndiko, body mass inowedzerawo. Kana pathologies nokutsanya dissimilation kwacho chitonge kuitwa uye kuderedzwa muviri uremu.

Kupatsanura pakati zvipenyu zvakasikwa dissimilation

Utachiona All inogona mapoka mapoka maviri, zvichienderana nemamiriro ezvinhu umo yacho dissimilation. Hazvina Kurovedza uye anaerobic utachiona. Wokutanga kunoda vakasununguka okisijeni, ekupedzisira havafanire kuedza nayo upenyu. At anaerobic dissimilation kubudikidza chinovira mberi, inova okisijeni isina enzymatic kugayiwa makemikari nyaya kupinda nyore. Somuenzaniso, lactic kana zvinwiwa chinovira.

Matanho dissimilation muna Kurovedza zvinenge: asi regadziriro Danho

Cleavage kuti Organic zvinhu zviri aerobes kuitwa matanho matatu. At nomumwe wavo pane dzakawanda chaiwo enzymatic siyana.

Danho rokutanga - regadziriro. Huru basa panguva ino ndezvako mu zvipuka zvine masero akawanda zvinenge zvomudumbu makemikari riri nemudumbu. In unicellular - lysosomal enzayemu. Mumwedzi wokutanga kutotanga mapuroteni anoora kupinda amino acids, mafuta vanoumba glycerol uye mafuta acids, polysaccharides yaora kupinda monosaccharides, nucleic asidhi nucleotides.

glycolysis

Danho rechipiri dissimilation - glycolysis. It kunoitika pasina oxygen. The chaivo sangano glycolysis ndechokuti zvinomirira Kuvamba kukamurwa uye shuga oxidation zvichiguma vakasununguka simba mumabhatiri muchimiro mamorekuru maviri ATP. It unowanikwa akatevedzana akatevedzana siyana rinova yokupedzisira mugumisiro paumbwe imwe morekuru shuga mamorekuru maviri pyruvate uye zvakafanana ATP. Zviri muchimiro adenosine triphosphate mumabhatiri simba chikamu inoganhura somugumisiro glycolysis vakasara kupararira uchava muchimiro kupisa. Nemakemikari pamusoro glycolysis: S6N12O6 2ADF + + + 2F → 2S3N4O3 2ATF.

In ezvinhu okisijeni kushayiwa iri chirimwa masero uye mbiriso masero piruvirat rwakakamukana zvinoriumba maviri: ethyl doro uye carbon dioxide. Ndicho chidhakwa chinovira.

Huwandu simba akasunungura panguva glycolysis haina kukwana kuti vaya zvinenge izvo chinofema oxygen. Ndokusaka mhuka uye vanhu panguva yakakwirira mumuviri nesimba muna tsandanyama iri synthesized lactic acid, anoshanda sezvo negadziriro yeparutivi simba kunobva uye rinoungana muchimiro lactate. A maitiro chinoratidza izvi ndiko kwaita kurwadziwa netsandanyama.

The okisijeni Danho

Dissimilation - chinhu yakaoma chaizvo kwacho, okisijeni uye Danho rechitatu uyewo inoumbwa maviri anotevedzana siyana. Tiri kutaura pamusoro Krebs kutenderera uye oxidative phosphorylation.

Munguva oxidation pamusoro okisijeni kufema piruvirata kune wokupedzisira zvigadzirwa, zviri CO2 uye H2O. Izvi anosunungura simba mumabhatiri muchimiro 36 ATP mamorekuru. Zvadaro, izvi chete simba zvinopa kwetunhu Organic zvinhu nenzira epurasitiki sikirini. Shanduka panowanikwa danho iri nokuda kuunganidza samolecular okisijeni mumhepo uye chitarisiko Kurovedza zvipenyu.

Nzvimbo oxidative phosphorylation (cellular afemeruke) vari munyika membranes pamusoro mitochondria, iyo vane samolecular transporter vakatakura chokufambisa pamusoro maerekitironi kuti samolecular okisijeni. The simba anobudiswa Panguva iyi diffuse aoma muchimiro kupisa, uye vamwe anoenda inotungamirwa ATP.

Dissimilation mu zvipenyu - ndiwo simba Exchange, maitiro riri sezvinotevera: S6N12O6 + 6O2 → 6SO2 + + 6N2O 38ATF.

Saka, dissimilation - kuva wanda kuitika nokuda Organic zvinhu kuti vave kare synthesized nokuda muchitokisi, uye vakasununguka okisijeni, izvo akapinda kubva kwokunze ezvinhu panguva afemeruke.
