U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Gelitaanka: Biyosynthesis aan shuruud lahayn ee lycopene ee dhirta eukaryotic iyo prokaryotic cyanobacteria waa isku mid, sida ay yihiin enzymes-ka ku lug leh. Isku-darka wuxuu ku bilaabmaa mevalonic acid, kaas oo loo beddelo dimethylallyl pyrophosphate. Ka dibna waxaa lagu dhejiyaa saddex molecule oo ah isopentenyl pyrophosphate (isomer of dimethylallyl pyrophosphate), si loo helo 20-carbon geranylgeranyl pyrophosphate. Laba molecule oo ka mid ah badeecadan ayaa markaa la isugu keenayaa qaab isku xiran si loo helo 40-carbon phytoene, oo ah tallaabada ugu horreysa ee loo maro biosynthesis-ka carotenoid. Kadib dhowr marxaladood oo qallafsanaan ah, phytoene waxaa loo beddelaa lycopene. Labada kooxood ee isoprene ee ugu dambeeya ee lycopene ayaa loo wareejin karaa si loo soo saaro beta-carotene, kaas oo markaa loo beddeli karo noocyo kala duwan oo xanthophylls ah.  Su'aal: Waa maxay kiimikada loo baahanyahay si loo bilaabo biosynthesis ee lycopene ee dhirta eukaryotic?
mevalonic acid (maadada loo yaqaano mevalonic acid)
