AP Bio Recap

<p>^ I think they're boring for everybody :)</p>

<p>Plus I don't see how lab questions test your ability to do labs anyway, nor do they really test if you have done a lab(though it would be an advantage)</p>

<p>My teacher obsessed over the AP labs, none of which worked as expected :(
,and of course the one that shows up looks like Greek to me</p>

<p>my teacher drilled the concept of notochord in which would be a pt for 4 b. a fool i am, i wrote everything i knew (and/or could fabricate) and wrote but forgot notochord.</p>

<p>How big of a deal is it if I wrote cortical instead of acrosomal?</p>

<p>


</p>

<p>That is exactly how an AP Bio essay should be written.</p>

<p>Concise is good, as long as you hit all the points. Concise with little substance might not be so good. Writing long drawn out answers without any helpful details won't give you any more points.</p>

<p>hmm... i have a feeling that even though some of my answers were "right", maybe a little creative, they won't be on the rubric >.<</p>

<p>for 2, do you think its right to talk about gastrulation and neuralation?</p>

<p>^Thats how you do it. During gastrulation the ectoderm gives rise to the nervous system. And nerulation is another Must in order to get credit probably.</p>

<p>I used carrier proteins with gated channels, mhc I & mhc II, and aquaporins. I'm hoping they give more points for aquaporins, since it is a relatively new topic in Biology.</p>

<p>lol thats great. aquaporins r very appropriate</p>

<p>did no one talk about the proteoglycan complexes for carbohydrates?</p>

<p>I mentioned glycoproteins, but I forgot their name. I just called them "proteins with carbohydrate chains that are attached" and said they were important for cellular identification. I hope thats good enough for credit; I think I can get one point for that; it would probably be two or three if I remembered the actual names and details. </p>

<p>For FRQ 2, the part about shattering glass; what should we have written about. I wrote about how neuron signals are communicated, because that's what I actually know enough to write about, but the question was pretty vague to me. Was it something where you could have written lots of different things and still get points?</p>

<p>^ I just put this.
External stimulus (sensory neuron) --> brain / cerebrum / spinal cord (interneuron) --> reaction (motor neuron). I thought this was ok for the glass shattering. I also talked about na / k+ pumps etc.</p>

<p>Also about that aquaporins. I think its fine but you wont get extra points. You would get it right still though.</p>

<p>ok, ok for #1 (not because its hard, but confusing) what did you meantioned, would glucose count?
others menitoned cholesterol does that count? i was really lost because i didnt know what that question was looking for i was almost about to write about lysosomes and microtubules and stuff like intill i realized they said macro.
Any ideas
What 3 did you guys choose?</p>

<p>i chose proteins, phospholipids, and cholestrol. I am pretty sure I read somewhere that carbohydrates ARE NOT in the actual membrane but outside of it.. but I could be wrong.</p>

<p>darn i thought that glucose was that big molecule that could not fit and those smaller molecules could, something like that, i was more confused by the wording of the question that the difficulty of it, i know i dominated #3, that was easy, but that wont get me a 5 or a 4. Oh well i never liked bio.</p>

<p>Yea same here. I thought plasma membrane was at first like mitochondria but then i remembered last year 2006 the first quesiton dealed with organelles and they wouldn't do it twice in a row.</p>

<p>glycocalyx, although many of you say that it is not IN the membrane, it is still part of and attached to the membrane. I'm pretty sure all books teach it as being part of the membrane, even though it's not within the phospholipid bilayer.</p>

<p>I definitely didn't think this test went that well... I left feeling more uneasy about this exam than any of my 7 other tests.</p>

<p>for the membrane question, it is proteins, lipids, and carbohydrates. The macromolecule that is not used is nucleic acids. </p>

<p>Also, according to 2002, a perfect score on the MC plus 0 on the FR was a 5 haha...not like that happened though...</p>
