<p>Cyclic phosphorylation is a primitive method plants use to create ATP through an electron transport chain. They use it when NADP+ isn't available for H+ to bind to. (I'm not sure if that was entirely correct...correct me if it's wrong) Electrons are again energized through photosystem I until NADP+ is available.</p>
<p>Noncyclic phosphorylation is the ideal pathway, a watered down version: Water broken down, electrons enter photosystem II and are energized, go through electron transport chain to make ATP, go to photosystem I and are energized again, NADPH created when NADP+ binds with H+ from water</p>
<p>I have a feeling that was completely wrong :P sorry its off the top of my head</p>
<p>Describe plasmogamy, karyogamy, and meiosis in fungi.</p>
<p>only a few more days till bio...time to cram?
oh and on the essays, remember to define define define! lots of points available for that..
be ready for the lab essay question.. my teacher is predicting a lab over dissolved oxygen..not good since we haven't covered that lab yet.</p>
<p>vin09 - that's kinda funny (lack of a better word), my teacher told us the exact same thing (she has a hunch the essay will be on dissolved oxygen).</p>
<p>I guess I'll review it the day before the tests.</p>
<p>kr0nnik - some of the ATP from the light reactions of photosynthesis are broken down and used in the dark reactions of photosynthesis. that's where the ATP goes.</p>

ATP is generated in photosynthesis, so why does photosynthesis convert light energy into Glucose, and then into ATP in cell respiration?? This seems like an "extra", even wasted, step.

</p>
<p>Glucose is used for storage and gradual, controlled release. If it were not produced, the plant could only live during the day (or maybe not because the ATP overload may kill the plant)....it would be dead at night...lol and OF COURSE, what do you think. the glucose is made for us to survive...duhhh.</p>
<p>and a very brief answer to koolmaria's question:
transduction- dna transfer process in bacteria
transpiration- plants losing their water
transcription- changing from dna to rna
transformation- a cell becoming cancerous</p>
<p>describe the functions of at least three plant hormones.</p>
<p>does anyone have any GENERAL studying tips for AP Bio? (especially if your teacher doesn't teach and you never really learned anything the first time around) </p>
<p>I took notes on the book up to 4th quarter and stopped b/c I was busy every weekend with school activities.We have not (and will not) cover the systems in class as well as classification of animals -- due to lack of time.</p>
<p>I generally do HORRIBLY (Ds and Cs) on the tests, even when I do study (by reading the book, reading over outlines, I have like 5 bio prep books, too...), so any advice would be appreciated.</p>
<p>Oh and I'm not taking the AP exam but we do have a 3 day final starting tomorrow.</p>
<p>i heard from my teacher who heard from his student hes tutoring who heard from her AP Teacher who heard from the college board that one FR might be on the nitrogen cycle. haha</p>
<p>How does the 5-4-3-2-1 thing work? Like, I know it's curved or something, but how many can you get wrong? I just took a practice and got 69 out 100 right on the multiple choice (terrible, I know!). So lets say I get a 30 of 40 on the essay. Percentage wise, that's a 71.4. So do I get a 4? Or what? I don't understand?</p>
<p>and 30 would be a really good essay score. if you are just trying to estimate your score i would lower it, its better to be surprised with a higher score on the real test than a lower score.</p>
<p>andreaaaaaaaa -
isn't transformation putting foreign dna into a cell? like that one lab our class did (i dunno if others have done it) with the transformed bacteria and the penicillin with the colony & lawn growth</p>
