Round 4: Tossup 11

Plants possess a variant of this organelle called the glyoxysome (“GLY-ock-see-zohm”) in which acetyl-CoA (“uh-SEE-til koh-AY”) is converted into succinate (“SUHK-suh-nate”) to allow carbohydrate 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[1])adreno•leuko•dystrophy (-5[1])and (*) Zellweger 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 that produces and breaks down H2O2.
