Anaboler Stoffwechsel

  • Helmut Kindl
Part of the Springer-Lehrbuch book series (SLB)

Zusammenfassung

Bei der Biosynthese der für die Zelle notwendigen Stoffe kommt es in vielen Fällen zu Arbeitsteilungen. Cytosol und Plastiden arbeiten zusammen. Ein Beispiel dafür ist die Bildung der Membranlipide, die je nach Verwendungsziel im Plastiden oder im ER gefertigt werden. Viele Wege der Synthese von Kohlenhydraten, in erster Linie der Transport-Metaboliten, sind im Cytosol lokalisiert. ATP und eine Menge an Hexose-Bausteinen kostet es die Pflanze, die Strukturen in Form der Zellwand herzustellen. Reservestoffe werden in eigens dafür spezialisierte Organellen eingelagert: Triglyceride in den Lipidkörpern, Proteine in den Proteinkörpern. Isoprenoide, Abkömmlinge der Aminosäuren und der Fettsäuren dienen der Pflanze als Signale.
