Our apologies for the Antarctic ocean oversight-this came up at the Mizzou mirror and was a simple oversight. It's been added to the line for future mirrors.Amizda Calyx wrote:I am curious to see the tossup on the mitochondrial inner membrane, since I don't think my submitted evo-bio tossup on mitochondria contained explicit membrane stuff.
I really liked the DSCAM clue for Down syndrome and the Jablonski clue for PS2. Overall I thought the bio was quite good, although the answerline for lysogeny needs to be expanded to include a prompt for "viral latency". I also got a bit tripped up by the combination of hearing what sounded like "tenocytes" (I think this was actually "tanycytes") and then later hypogonadism + anosmia for the hypothalamus tossup and answered with cilia, although I'm sure the clues made it obvious that the structure was much larger.
The answerline for the Southern ocean needs to include Antarctic ocean -- that was a really frustrating neg that I'm surprised didn't affect the earlier mirror.
The Mitochindrial inner membrane tossup:

Carboxyatractyloside and bongkrekic acid are toxins that inhibit a protein in this structure. In humans, the SLC25 family of genes code for proteins in this structure, which includes the citrin protein and three AAC [A-A-C] proteins. Glutamate and alpha-ketoglutarate are respectively antiported with (*) aspartate and malate through this structure, because this structure is impermeable to NADH [N-A-D-H] and NAD+ [N-A-D-plus]. Cyanide poisoning affects a protein in this structure that converts diatomic oxygen into water. Complexes one through four aid in pumping protons across this structure, which contains folds called cristae. For 10 points, proteins used in oxidative phosphorylation are found along what organellar phospholipid bilayer?
ANSWER: inner mitochondrial membrane [accept word forms do not accept “cell membrane”, prompt on partial answer of “mitochondrial membrane” or “membrane” with “Which one?”, prompt on “inner membrane” with “inner membrane of what?”, prompt on just “mitochondria” or “mitochondrion” with “Where?”] <Ed.
