Yay, we finally got to see our Java teacher! He’s a really cool guy, and he explains stuff in a really clear way. I wish he had been here the first few lessons so he’d get us acquainted with it better. Anyway, now I’m all inspired to program and stuff! Okay, I’d better get to bed now though.

Oo omg! Last night, at around 1:30 (right before going to bed), I saw Miller and Urie (ew is that how you spell it? it looks wrong) on the Discovery Channel, and they were demonstrating how organic compounds were first formed! They like electrocuted this thing, it was so awesome. Then these things accumulated on the sides of the flask, and they looked at them under the microscope and they were like little cells! Only, they were actually phospholipid bilayers, and they were so cute! Just little circles with nothing in them. But the phospholipid bilayer is an awesome kickass thing. *gets excited about bio all over again*

Textbooks should be funny. If I were writing a textbook, I’d put in odd little comments in there, just to entertain, like in some parts of my chem book: “Asking for a sophisticated explanation from a simple model is like expecting to get an accurate mass for a diamond using a bathroom scale,” and “We often learn by making mistakes. (Try to remember this when you get back your next chemistry test.)” Hahahha! I also love that thing I found in my biology book back in 9th grade – “What would you do if you were interested in heredity, had several kinds of purebred peas, and also knew how to cause cross- pollination? No, pea soup is not a good answer.”

Grr. I was planning on memorizing the whole packet tonight and memorizing stuff on my own tomorrow night, but that seems unlikely; however, I’ve finished memorizing all the enzymes! I suspect that I might have memorized every single piece of information Gaida has typed up for me, but we’ll find that out tomorrow when I get people to quiz me.. it’s fresh in my mind right now (although the word I’m having the most trouble with is Rhizobium, the species of bacteria which does nitrogen fixation in the root nodules of legumes). Nitrosomona makes nitrite, and Nitrobacter makes nitrate, yeah baby. Chem knowledge rules! Now I have a great appreciation of bio! Let me see if I’ve memorized these words.. oxaloacetate.. acetaldehyde.. *looks them up* .. good! *feels good* But I think I memorized Rhizobium by now too. BIO KICKS BUTT. Today I am so happy. Why didn’t I think of studying bio before?! Now, whenever I’m feeling down, I’ll just whip out my notes from last year and study them, mwahahahah! Alright, so maybe that’s just a bit dorky. *cough* But some enzymes scare me because some are produced in the pancreas and the others in the small intestine.. and enterokinase is a weird little thing which activates trypsin (from trypsinogen), and then trypsin turns procarboxypeptidase into carboxypeptidase (which removes amino acids one at a time from its carboxyl terminus) and chymotrypsinogen into trypsinogen. Although I don’t quite get the function of peptidyl transferase.. I think he worded it a bit wrongly so I’ll just ask him tomorrow. And I also don’t get splicesomes. Grr.

Sorry for throwing out all these weird names at you. I’m just trying to make you as happy as I am right now!! Hehe j/k.. But I’m not really bragging.. or maybe I am. You decide, because I don’t care. Tis my blog and I can write about whatever I want! Besides, it helps me learn, believe it or not.

Besides, geez, maybe there’s SOMEone out there who’s interested!

Learning bio makes me happy! I’ve already memorized over half the enzymes that Mr. Gaida gave to me on a list. Some of them I’d never heard of before, and the others I didn’t really get detailed information on. I sooo want to take AP Bio again! In fact, I just had a weird urge to buy books on biochemistry and just read them in my free time.. haha.. yeah right. Anyway, this is so fun! Yaaay!

By the way, a recap: the light reactions on the thylakoid membrane produce ATP and NADPH (also oxygen), and photosynthesis uses up 12 NADPH and 17 ATP to make one molecule of glucose (done in the stroma of the chloroplast). Glycolysis is done in the cytoplasm and produces 2 pyruvates (pyruvic acid) and a net gain of 2 ATP and 2 NADH. Then, there is alcohol fermentation (done in bacteria and stuff; pyruvate to acetaldehyde to ethanol) and lactate fermentation (done in humans; pyruvate to lactate). Anyway, in the Krebs cycle a CO2 is removed from a pyruvate molecule and NADH is formed, and coenzyme A turns it into acetyl CoA, which is then attached to oxaloacetate (a 4-carbon compoud) into citric acid (a 6-carbon compound) then those Cs are taken off and out come 8 NADH, 2 FADH2, and 2 ATP (from one molecule of glucose). Then, the ATP is used in energy and stuff, but then in oxidative phosphorylation the NADH and FADH2 give their electrons to the electron transport chain and that forms, like, 32 ATP which is oh-so-fun. And there ya go, that’s a total of 36 ATP produced by breaking down glucose. Cool, huh?

Of course, there are other details that I didn’t care to go into in a blog. Sorry – in my last entry I said I wouldn’t explain the whole process and I just did.

Also, did you know that the enzyme lysozyme is contained in bacteriophages, and the host bacteria produces this enzyme that breaks down their bacterial cell walls? Did you also know that this antibacterial enzyme is contained in tears, saliva, and other bodily fluids? Well, you know now!

Science and music are my biggest passions.

Yaaay! I just memorized all of the energy cycles in, like, half an hour! It took me hours to memorize them last year!! I guess it was also because of the AP pressure and I had to know everything and explain it well. But Science Bowl is better (even though there’s pressure), because there are just one word answers. On the other hand, there’s more risk there and you need to know everything 100% because you can’t BS your way through like you do in the AP. *grin*

Yaaahh! So now I’m taking a small dinner break, and then I’m going to memorize some biochemicals.. namely, a list of antibodies, enzymes, proteins, and other goodliness. OMG! I’m so happy. I would right now write out all the steps of photosynthesis and respiration (I swear I would), but I suspect that not many people would understand or get it. AP Bio pride!!!!!

*rushes to eat*

Today I went tutoring at school to fulfill the National Honors Society requirement… We have to have 6 hours, and I completed 3 hours just by sitting there chatting with Andrea.. well, at this one point I showed people from my AP Chem class how to solve yesterday’s quiz problems and I explained the angiosperm life cycle to Andrea, but that took about an hour. At least I got the hours!

I’m so happy! My tummy tickles from happiness, the sun’s out, and everything looks so great. *smiles*

Okay, I’m snapping out of the “not writing on my blog and not changing imood because I’m feeling bad” crap, because things are going so well now. Besides, imood got new faces to put up, so it’d be a shame to not use them!

It’s been a hectic week, and it’s also a hectic weekend. I have to read about 671 pages until Tuesday night, preferably earlier than that, but I don’t think that’s happening anytime soon. I also have to memorize Honor Choir music and miss school on Friday because of it, but I’ll worry about that after I am done with my timed writing on Wednesday. I also need to save all my e-mails from gurlmail until November 15th, but I really don’t see that happening. It just requires too much time and I need all the time I can get to read. So maybe I’ll sign up for the “premium” deal they’re offering until I find the time to download e-mails. That will be a great load off my back, because the last thing I want is to lose years’ worth of very valuable e-mail.

I saw K-Pax yesterday with a bunch of friends. GO SEE IT. It is soo friggin awesome. That is all I have to say about that.

I don’t think I have anything else to report for now. Oh, I’d paid $10 to get my AP Biology answer booklet back, so I just got that in the mail today. There are no correction markings on it or anything, but I just wanted to see the essays I’d written under time pressure. I’d drawn more diagrams than I thought I had! It’s such a shame that I don’t remember any of that stuff now. Also, it really sounded like I’d crammed in a lot of information the night before, because I’d stuck in all these terms that probably would have been impossible to just remember off the top of my head.. like I remember I’d memorized all the energy cycles and everything. I never remember those for more than a day. Haha. I want to show my friends. I am so proud of it. Yaay.

Alright. That’s it for today. I am back to blogging, woohoo.

Speaking of blogging, I’ve been reading this blog for a couple of months now. It’s an anonymous blog that was started when the guy broke up with his girlfriend. He occasionally writes down his thoughts, feelings, and encounters. It’s really cool.. I love reading it. Just scroll down to the very, very bottom and start from there while I continue doing homework. Until next time!

I’m soo tired today.. Ugh!! All these people keep calling me all the time! Soha calls me every night anyway, and yesterday Nuruddin called me and we talked for hours! Damn it, I went to bed at 12:30. That ain’t healthy. So tonight, I’m just going to go to sleep as soon as (well.. perhaps an hour or two after) I come from class.

Tomorrow’s going to be a very busy day! I’m gonna get out of the house at 8:00 and come back home at around 7:30 or so! But I like days like that.

Yay!! I got a 5 on my AP Bio exam! I won $2,500! Hehe. Good to know that my first AP class has been a success.. hopefully I’m not traumatized. I hear that the AP Chem test is really hard, though.. I gotta take that next year. I hope I don’t slack off too much.. but, as Mr. Gaida said, I’m a slacker! But.. he says that to everyone. *grin* Even those who aren’t slackers. And that really pisses those people off. Hehe!

Today in the morning my mom and I weren’t really getting along so well, and I come home after class and find an e-card from her! She rules! Yay mom! *big grin*

Ugh… headache! We have TONS of French homework tonight. We haven’t had this much before.. Heck, I usually don’t have this much schoolwork during a regular school day! Hehe.. Oh well. Ooo! We learned past tense in French today! And tomorrow — commands! Yes! This thing is so fast-paced! Yahaha!

Oh man, my mom just brought me the calzone we took home last night, and it’s sooo good! And she also made me ayran.. it’s this drink and there’s yogurt, water, and salt in it. Now that I think about it, the Americans here would probably think it’s weird. But it’s a really common drink in Turkey, it’s almost as common as coke. And now I shall eat.

I got a 770 on my biology SATII test!! (That’s good.. it’s out of 800.) Hm.. it said something about a 99 percentile, I don’t know what that means.. but… hey! IT’S A GOOD THING! YAH MON!!

In Gaida’s class we’d been doing a pig fetus dissection lab that we started last week, and I hadn’t touched it at all until today.. Today I did all the dissection myself because I felt like it.. and it was the most important part, too.. last week we had to take off the skin and look at the muscles, and today we opened it up and looked at the organs and stuff. Now that I think about it, it’s so sad. It makes me wanna cry just about now. But back then I was having fun. Soha was so disgusted because I squeezed the stomach and juice came out. It is sort of nasty. Mr. Gaida had said that we didn’t need gloves, so I was the only one not using gloves.. I figured it’d be more worthwhile that way. I don’t like putting on gloves. It was really fun, but my hands smelled until lunch.. because the chemical that preserves it smells really bad. Oh well. Somebody from 2nd period said that their group took out the intestines and made the pig jump rope with it and took pictures. Okay, that’s all I’m writing for now because my mom just brought me food. I’d like to keep it in my stomach, thank you.
