Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Biosynthesis na lycopene mara izini a cikin tsire-tsire eukaryotic da a cikin cyanobacteria na prokaryotic iri ɗaya ne, kamar yadda enzymes ke ciki. Haɗuwa yana farawa da mevalonic acid, wanda aka canza zuwa dimethylallyl pyrophosphate. Wannan sai a hada shi da kwayoyin uku na isopentenyl pyrophosphate (wani isomer na dimethylallyl pyrophosphate), don samar da 20-carbon geranylgeranyl pyrophosphate. Biyu kwayoyin na wannan samfurin ne sa'an nan condensed a cikin wani wutsiya-to-wutsiya sanyi don ba da 40-carbon phytoene, na farko aikata mataki a carotenoid biosynthesis. Ta hanyar matakai da yawa na desaturation, phytoene ya canza zuwa lycopene. Ƙungiyoyin isoprene biyu na lycopene za a iya yin amfani da su don samar da beta-carotene, wanda za'a iya canzawa zuwa nau'ikan xanthophylls.  Tambaya: Wace sinadarai ake buƙata don fara nazarin halittu na lycopene a cikin tsire-tsire eukaryotic?
