Biology SAT II POST-EXAM discussion!

<p>For 28 Chemical II, I think its a coenzyme rather than an inhibitor.</p>

<p>again according to wikipedia :stuck_out_tongue:

</p>

<p>Didn’t the enzyme trigger a greater rate of action? If so it could be a coenzyme, since it required the help of Chemical I to induce the original reaction, and then increased the rate of reaction afterwards.
But I really don’t know…</p>

<p>^No. Chemical II was the one that resulted in the straight horizontal line, showing a stop in the enzyme action, meaning that it WAS an inhibitor. </p>

<p>What did you guys get for the graph? I put the one where it eventually flattens out, but without the little bump.</p>

<p>ouch, i got that one totally wrong then. youre talking about the inversely proportional one right?!</p>

<p>the graph that I chose is the one that looks similar to what the graph of sqrt(2) would have been like.</p>

<p>sour i put the same graph, can we get a confirm on this? and add it to the updated list?</p>

39which graph is bad - pie graph, can’t go off of a 100% total basis
40, 41, 42?-tree plots - no difference in number of conifers between plot 1 and 2, cedar affected by everything but available nutrients
43,44,45pediegree chart of hemophilia - all the square blacks were xry, all the circle white where xRxr or xRxR, all the circle black where xrxr

75which of the following is right DNA combination- cytosine to guanine
76what does graph look like when there is no more substrate left in enzyme reaction: it goes up and then levels off (quantity of products)</p>

<h1>39 about the wrong graph fixed, added 76 confirms what we just said! :P</h1>

<p>“there were no questions about urey and miller right”
On the E section, there was a set of questions on their recreating-life-on-early-earth experiment.</p>

<p>can i get what the questions were exactly for 40-42? these were the questions referring to removed deciduous trees</p>

<p>damn, what were those last 4</p>

<p>there was a question that went, “total interrelationship with the environment blah blah …” ANYONE got the answer?</p>

<p>WOW. Last year we were only able to recreate about half the test (although we did all the hard questions). That’s a very impressive list.</p>

<p>OH, i said niche! add that to the list!</p>

<p>WHich book did you use?
And was it helpful? Thanks!
TM</p>

<p>I used:</p>

<p>Kaplan
REA
PR
Cliff’s AP</p>

<p>umm I used Barron’s with some Sparknotes practice tests, and found that surprisingly, a tiny bit of the random stuff Barron’s includes for no good reason showed up. It would be really easy to pinpoint your weaknesses using any practice test though (for me, it was circulatory and respiratory systems, classification, and some molecular details) Good Luck if you’re planning to take it soon!</p>

<p>3 until completion! we have to do this. come on guys!</p>

<p>niche! (?)</p>

<p>So the FINAL list so far:</p>

77 The total interrelation with an organism to its environment is its niche</p>

<p>yes niche! for the “total interrelationship with the environment blah blah …”</p>

<p>blargh u guys have “waves that plants dont absord” and “waves that insects use” on there twice. ur missing the ones that snakes use to detect other animals and the highest energy one that humans can see (violet)</p>

<p>nvm sorry, but u do have those 2 on there twice i believe</p>
