<p>the process of deammonification is a break down... but taking ammonia and making urea is a production... so it was a trick question..</p>
<p>wikipedia:
"The individual atoms that make up a urea molecule come from carbon dioxide, water, aspartate and ammonia in a metabolic pathway known as the urea cycle, an anabolic process."</p>
<p>either way its a bad question...while rbc's may have been the best answer choice its still a wrong answer choice.</p>
<p>Deammonification of urea (or something)....
....breakdown of ammonia to create urea.</p>
<p>i can only find online for deammonification that it deals with taking ammonia and making Nitrogen gas.... for plants... if u deammonified urea... you would remove it...</p>
<p>de in latin= away, off, to pull, from, down.....</p>
<p>do u agree now?</p>
<p>no..........</p>
<p>barrons says-
"liver produces nitrogenous waste urea from protein metabolism"</p>
<p>idk if that helps...</p>
<p>Like doubledian, no.
I've researched a bunch of websites (too lazy to name and list) and NONE of them, except wikipedia, have mentioned red blood cells as a MAIN function of the liver. All of them have mentioned a relationship b/t ammonia and urea.
Now whether or not this relationship fits into your nicely described latin root bullcrap, i do not know.</p>
<p>I don't wish to argue with you anymore, thank you.
You believe what you want, I'll believe what i want.</p>
<p>doubledian,... you are just too ignorant, when the facts are starring you straight in the face.... w/e..... it's still a minus 1/4 on the sat... believe it or not.</p>
<p>if u even took biology or chemistry, i'm surprised you passed... by thinking that deammonifying is an anabolic process, when it is clearly catabolic.
I'M DONE..... we need more smart science ppl in here.. thanks for tryiny ac37</p>
<p>The answer to a question isn't necessarily always the RIGHT answer, it is the BEST answer! Just because all the choices were possible that doesn't make the liver question a bad question. I disagree with you GAclassof2008, just because the liver does it in an embryo, the bone marrow takes over later, making the "the liver does not produce red blood cells" the BEST answer.</p>
<p>And seriously, you need to chill. Who died and made you genius?</p>
<p>Lol i don't know why you're trying to be so mean, i'm not saying you're wrong or anything. Like Sam said, it's about the best answer. they're all right, but just the red blood cell answer is the best.
:</p>
<p>The liver does not produce red blood cells, so, I don't see why it wouldn't be the right answer. And didn't the question ask about primary functions of the liver? If the liver produced red blood cells in the embryo, but the bone marrow takes over later, for the rest of life, then one of the liver's dominant functions is not producing red blood cell. It may seem like a leap in logic, but really, that is the best answer. That's what I put as well.</p>
<p>Well if RBC isn't right..than the nation got the question wrong. LOL
so It will help the curve. haha
But I think that everyone else is right. Red blood cell production mainly occurs in bone marrow not in liver.</p>
<p>we will all argue the answers we put down until death. </p>
<p>i think if you honestly look at the damn liver question its obvious the answer is red blood cells. the reason that is a choice is because the liver breaks down red blood cells to make bile, as to trick people.</p>
<p>i also remember it saying "adult" liver and "primary function"</p>
<p>also don't trust wikipedia! i could post a made up article on there if i wanted the information has no merit</p>
<p>deammonifying was not even an answer choice</p>
<p>deamination not deammonification. I don't know who confused it, but the sat definitely said deamination, which is the removal of amine groups from peptides. It's how protiens are digested.</p>
<p>I recall seeing this question and thinking, ohh, barrons has a list of 4 things the liver does and making red blood cells is the only one not on there. this question is really not that hard.</p>
<p>*** we really need some ppl who really studied bio.
Bone marrows make RBCs, not liver.
what liver does is recycle RBCs, not produce RBCs.
damn, even confusing me.</p>
<p>GA stop trying to make yourself feel better because you got it wrong. its you who will be losing a 1/4 of a point</p>
<p>seriously... this test was pretty easy... i don't expect an 800, nor do i really care if i get one. I mean it would be nice and sure, i'm shooting for it, but i'm not gonna get upset if i get like a 700... i expect a 700 or above.</p>
<p>that's exactly what i'm thinking</p>
