A photosystem possesses an antenna complex (contains around 200-300 light-harvesting pigment molecules) and a reaction centre. Sammanfattning - Photosystem 1 vs Photosystem 2 De viktig skillnad mellan fotosystem 1 och fotosystem 2 är det fotosystemet 1 har ett reaktionscentrum som består av klorofyll en molekyl av P700 som absorberar ljus vid en våglängd på 700 nm. Å andra sidan har fotosystemet II ett reaktionscenter innefattande klorofyll, en molekyl av P680 som absorberar ljus vid en våglängd på 680 nm. Start studying photosystem 1 and 2.
