I had form CT, and one of the answer choices was astrocyte. Does anyone remember this question? Do you know what the answer was? I think it was "which is least likely" so I chose astrocyte since it sounded like it was an astronomy answer! And another question was something like ATP is part of a. b. c. ogliosaccharides d. something else. I don't even remember what I chose, but I don't think I did ogliosaccharides. Does anyone know which was the right answer? And muscles contract--does Z get shorter? Or actin, myosin, or both actin and myosin get shorter? There was an orgo passage where it referred to 2a and 2b and 3a and 3b but it only showed 2 and 3 so I assume that they were referring to enantiomers? Am I right? and 5a and 5b were enantiomers? So in that question where it said which were conformational isomers, was it 4a and 3a, or something like that? Thanks! I hope I guessed right!!! <img border="0" alt="[Clappy]" title="" src="graemlins/clappy.gif" /> Oh and the first passage there was a question with c. no ERGs or whatever that was, and d. no estrogen receptor. I put c, is this right? I hope!
