Potosintesis
An potosintesis (Ingles: photosynthesis) iyo an proseso na ginagamit kan tinanom asin iba pang organismo para maliwat an enerhiya kan liwanag pasiring sa enerhiyang kimikal, na sa paagi nin selular na respirasyon, pwedeng mailuwas dagos para magamit sa metabolikong aktibidad kan organismo. An enerhiyang kimikal na ini iyo natatago sa mga molekula kan karbohidrato, arug kan asukar, na iyo nasintesa gikan sa karbon dioksido asin tubig – kaya pigpangaranang photosynthesis, gikan sa Griyegong phōs (φῶς), "liwanag", asin sunthesis (σύνθεσις), "sabay na pagkaag".[1][2][3]
Harus pigluluwas an oksiheno bilang ati na produkto. Kadaklan nin mga tinanom, algae, asin cyanobakterya iyo minaakto nin potosintesis asin an mga organismong nasambit iyo inaapod na potoawtotropo. An potosintesis iyo may dakulang responsable sa pagmokna asin pagmantinar kan oksihenong kontento sa atmospera kan Kinaban, sagkod iyo nagsusuplay kan kadaklan nin mga kinakaipong enerhiya para sa mga buhay sa Kinaban.[4]
An pinakaenot na potosintetikong organismo iyo pwedeng nag-ebolbar nin amay sa ebolusyonaryong uusipon kan buhay, sagkod iyo harus pwedeng naggamit nin mga ahente kan reduksyon arug kan hidroheno o hidrohenong sulpido, imbes na tubig, bilang gunuan nin mga elektron.[5] Dagos nagluwas an mga cyanobakterya; an sobrang oksiheno na saindang namokna iyo direktang nag-ambag sa oksihenasyon kan Kinaban,[6] kaya nagin posible an ebolusyon kan komplikadong buhay. Sa ngunyan, an normal na rikas kan pankinabang enerhiyang naguguno nin potosintesis iyo harus 130 terawatts,[7][8][9] na iyo harus walong beses kadakula kan presenteng pagkonsumo nin kuryente kan katawohan.[10] An mga potosintetikong organismo iyo nagliliwat man nin harus 100–115 na bilyong tonelada (91–104 petagramo) nin karbon sa biyomas kada taon.[11][12] An penomena na an mga tinanom iyo nakakakua nin enerhiya sa liwanag – dugang sa ere, daga, asin tubig – iyo enot na nadiskobre kan 1779 ni Jan Ingenhousz.
