Packet 4: Tossup 11

Plants possess a variant of this organelle called the glyoxysome (15[1])(“GLY-ock-see-zohm”) in which (15[1])acetyl-CoA (15[1])(“uh-SEE-til koh-AY”) is converted into succinate (-5[1])(“SUHK-suh-nate”) to allow carbohydrate (-5[1])synthesis prior to germination. This organelle is where very-long-chain fatty acids are oxidized, a process that is dysfunctional in disorders (-5[1])such as (-5[2])adreno•leuko•dystrophy (-5[1])and (*) Zellweger (10[1])syndrome. (10[1])Firefly luciferase is localized to this organelle, which contains the catalytically-perfect enzyme catalase. (-5[1])Reactive oxygen species (10[1])are digested by this organelle (10[1])and converted to its namesake molecule. (10[1]-5[1])For 10 points, name this organelle (10[1])that produces and breaks down H2O2. (10[1]-5[1])■END■ (10[3]0[13])
