WebSep 15, 2024 · In the brown-colored diatoms, fucoxanthin absorbs green light and transfers the energy to photosynthetic chlorophylls that emit part of this energy as red fluorescent light (right). WebThe genome revealed similarities between nonphotosynthetic diatoms and apicomplexan parasites for provisioning NADPH in their plastids and highlighted the ancestral absence of a plastid oPPP as a potentially important constraint on loss of photosynthesis, a hypothesis supported by the higher frequency of transitions to parasitism or ...
Web2 days ago · Between the PSII and the cytochrome b6-f, the photosynthetic chain of diatoms can contain plastocyanin (PCn), a Cu-containing protein carrying electrons. The decrease in rETR PSII suggests that P. delicatissima may contain some PCn, which functioning might have been limited by Cu. A lack of PCn electron carrier might have … WebOver the eons,diatoms acquired new genes, shapes and complex metabolisms. They’ve becomechampions of photosynthesis, while retaining many properties of animal cells. With other photosynthetic protists, they produce oxygen and absorb CO2.
