<p>wait are they just there for future storage? so in case the same pathogen comes into the body again they can then differerentiate into plasma cells for the secretion of antibodies?</p>
<p>I think they just kind of circulate the body and wait until they match up to the antigen right? I don’t think they have any other function than differentiating when needed</p>
<p>Yeah, I agree with Batman. It’s only when they receive an antigen that they mature into plasma and memory B cells.</p>
<p>hmm. i see. thanks</p>
<p>that’s my line 8888</p>
<p>thanks guys</p>
<p>hmm. i see gracias.
so what’s the triple threat process?</p>
<p>What is this bicarbonate business and respiration? On the online quiz…it buffers other acids? I thought hemoglobin does that. And then carbon dioxide moving through blood…in the form of bicarbonate ions? In the diagram itself, it clearly shows that Hb does that (although i understand that it travels in the form of the ion too</p>
<p>The oxygen gets combined with a protein called hemoglobin, and the CO2 gets combined in a few ways. It actually reacts directly with water to form carbonic acid. Some of it can combine with hemoglobin molecules by a reaction with N-terminals of hemoglobin chains. But most of the CO2 is carried in the form of bicarbonate.</p>
<p>did anyone ask Forte how similar the online quizzes would be to the test?</p>
<p>Didn’t go to one lecture. lol But I mean that’s so double-edged. Both have the truth and it’s not like it asks for the best answer.</p>
<p>oh man that suuuucked.</p>
<p>good ****ing game, i had to guess on a lot of those</p>
<p>what was the one where it asked about the equilibrium membrane potential at rest of the K+?</p>
<p>that was butt rape trickery.
what were the answers mech? Is that the graph one or the regular? I think for the graph, I put A where the threshold is. I was trying to remember those diagrams but they weren’t helping. All I know is that at rest, it’s more negative inside and allows for K+ permeability because it reabsorbs back in if that helps</p>
<p>i put D for K+, at the lowest point when it’s most hyperpolarized, but it was just a guess</p>
<hr>
<p>i’m looking in the book and i think i guess that right, yes!</p>
<p>was it just me or was this exam extra tough? i didn’t really study enough for this so i dunno if it was just me or if it was hard for everyone…</p>
<p>Well I finished lectures last night at 9 and studied until 2. haha There was a good amount of questions (like 15-20) for me that was either tough as **** or just tricky. Like the action potential moving down the axons: i got confused by the answers b/c isn’t it true that myelin go faster but then also it switched the potential one at a time?</p>
<p>i thought it was hard, but i certainly did not study as much for this one as i did for Malkin’s. i didn’t even review the muscle lecture…so the last page was pretty much epic fail for me lol.</p>
<p>i’m pretty sure the answer to that one was the myelin choice…</p>
<p>well **** I thought it was too until I saw the other choice.</p>
