Dark chokutambudzika photosynthesis

Okisijeni - anokosha chezvinonhuwira kuvapo zvose upenyu Panyika. Zvinoshamisa, chaikosha ichi panyika, kunyange zvazvo pfungwa yaro mudenga vanotozvikuvadza zvinoderedza maererano mamwe masayendisiti, ndiye vospolnimo kumucheto. Kunyange zvakawanda zvinoshamisa zvinoita kuti synthesized kubva kupfuura iripo zviwanikwa - mvura, chiedza chezuva uye carbon dioxide. Uye anoita muitiro uyu chirimwa chinoshamisa.

Chokwadi, tiri kutaura pamusoro photosynthesis - zvinoshamisa chisikwa zvakasikwa. Pasinei chokwadi kuti masayendisiti akadzidza kwazvo nyaya iyi, kudzokorora nhanho photosynthesis murabhoritari shamisa nhasi.

Izvi zvinogona rakakamurwa muzvikamu zviviri:

• Light-nemataundi zvinoitwa photosynthesis.
• Dark chokutambudzika photosynthesis.

zita ravo zvakajeka kuti chikamu muitiro wokutanga kunoitika muchiedza, kureva kuti kutora chikamu chezuva. It rinowanikwa chete egirini zvinomera, nokuti ane chloroplasts - chaiwo okunze ari membranes rakanzi ATP kwetunhu - mamorekuru umo simba inochengeterwa.

Kana paine chezuva photons pamusoro Mashizha miti ine chlorophyll rikauya rokutendeutsa chezuva simba kupinda nesimba ATP mamorekuru kare ataurwa pamusoro. Uyezve, nokuda kubviswa rehydrogen maatomu maviri kubva mvura mamorekuru (izvo kunoitika achishandisa chezuva) kuumbwa NADPH Morekuru. Manyowa mvura Morekuru anobviswa rehydrogen maatomu maviri, unoramba uinemi vakasununguka okisijeni, izvo anopinda mhepo. Saka, zvibereko photosynthesis muchiedza chokutambudzika - ndiko:

• okisijeni;
• simba Morekuru ATP;
• NADP mabhomba rehydrogen H2.

Chinoshamisa paumbwe okisijeni iri kwacho hakusi chinangwa chikuru. Asi, ndiko divi kushanda. Next anouya The rima chokutambudzika photosynthesis kana chemosynthesis, izvo zvakananga nidzwa zvibereko wokutanga chokutambudzika. Ngationgororei izvozvo zvizere.

Zvechokwadi, chinangwa kwacho hakusi paumbwe okisijeni. Nerima chokutambudzika photosynthesis kunoitika mune imwe chikamu shizha - zvayo chloroplast stroma. Pakazopera chiedza kutotanga chirimwa Rinotarisira wemari anoyevedza simba rakawanda mamorekuru - ATP uye NADP H2 saka chiedza chikamu chiri zvisisadiwi. Zviri kuburikidza mamorekuru aya synthesized Organic okunze. Hazvina musoro kuti dambudziko simba Morekuru ATP - simba anopa dzinotsanagura kwetunhu, apo basa NADPH H2 - kupora.

Pakutanga kuyaruka, morekuru iri oxidized achidzikisa mumiriri, yokuti vaviri rehydrogen maatomu kunyangarika, kuti goho anopa wakachena morekuru NADPH. Panguva iyoyowo, ATP anopa phosphoric iine acid vakasara, akatendeuka kupinda ADP. pezvakaitwa maviri izvi zvichiitika mukati chizvaro pakati jira. The richangobva kuwana mamorekuru ipapo kudzokera vatarisana mashizha, izvo zvinoita kuti tikwanise kudzokorora yose muitiro chechiedza chokutambudzika. Zvisinei, ichi hachisi chinhu chinokosha nedanho photosynthesis, isu chete kuzivikanwa cyclicity uye kutevedzana remapazi kuti kuitika mashizha.

The yokupedzisira yemudzimu kuyaruka anova Shuga - ane Organic remubatanidzwa kwakakonzerwa nyore shuga. Kokutanga rondedzero yakatodzama kubatana kwetunhu Morekuru ichi aigona Melvin Calvin. It Vakawana kuti zvose mamorekuru vanoonekwa sevamwe chiedza kutotanga - simba uye kuderedza mumiririri - urimowo kwetunhu. Uyezve chinokosha yokuva nyore shuga vari 6 mamorekuru kuti carbon dioxide inobvisa (CO2), rehydrogen maatomu 24 6 mamorekuru mvura:

6SO2 + 24H + ATP C6H12O6 + 6N2O.

Nerima chokutambudzika photosynthesis zvinomera zvinokosha nokuti kuwedzera Shuga iyi pave zvakasiyana siyana amino acids, nucleotides, mafuta acids uye glycerol.

Photosynthesis - zvikuru nemamwe dzinongoitika muitiro. It kwete chete ndiyo kiyi kuramba kuramba azvipire okisijeni iri muchadenga uye ari ozone layer asiwo ari kukwana hunhu apo zvinhu vakasikwa kubva inorganic Organic.
