Fotosynthese
chlorofyl
6 CO2 + 6 H2O  C6H12O6 + O2
licht


 Fotosynthese
o ≠ namen voor = proces
o Fotosynthese (nadruk op noodzaak van licht)
o Zetmeelsynthese (ook zetmeel wordt gevormd)
o Bladgroenwerking (vind plaats in bladgroenkorrels)
o Koolstofdioxide assimilatie of C-assimilatie



1. PIGMENTEN VAN DE FOTOSYNTHESE
 Met behulp van chromatografie (scheidingstechniek om mengsels van
moleculen te scheiden)
 Schrijven met kleur
 Oplossen in de loopvloeistof – absorberen aan de drager
 Stationaire fase (papier) + mobiele fase (loopvloeistof)
 Soort zoekt soort (polair – apolair)
 Chlorofyl b – chlorofyl a – xanthofyllen – carotenoïden
 P132 weetje
Absorptiespectra van fotosynthetisch actieve pigment
 Alle bladpigmenten ( < chromatografie) betrokken
bij de fotosynthese
 Ze absorberen licht van ≠ golflengten
(absorptiespectrum: waaier van golflengtes die
geabsorbeerd worden)
 Voornaamste: chlorofyl a (absorbeert rood en blauw
– reflecteert groen)
 Chlorofyl a en b samen: groter bereik
 Carotenoïden (ϐ-caroteen en luteïne: absorberen
blauw – reflecteren geel en oranje


2. FOTOSYNTHESEPROCES
 Waar? In chloroplast
 2 deelprocessen
o Lichtreactie: vorming van ATP en NADPH (licht E -> chemische E)
o Calvincyclus: omzetten van CO2 naar glucose
met verbruik van ATP en NADPH
