<p>Hi guys so I thought I was pretty good at AP Bio and then we came across cellular respiration which is sooooo hard I dont understand it ahhhhh. Are there any great websites or anything that helps simplify it? How do I study this so that I get it and pass my tests? Our other topics were so easy and then wham cellular Respiration is so hard. how did you learn this chapter? What worked for you?
P.S. If it helps I am using campbell ap edition, and I have cliffs ap, barrons, and crash course as my review books thank you!</p>
<p>My advice to you is just go on google and type in cellular respiration ap biology. You’re bound to hit a site that explains it better then your textbook. I was having trouble w/ a lab+concepts in campbells (Organic Chemistry) so I just looked up the concept w/in Ochem that I was having trouble w/ and I found the better explanation online. After wards I added that to my notes (to explain it better). It’s the process of finding the info that’s rewarding and helps you learn best. Peace and best of luck.</p>
<p>I had a little trouble with Cell Respiration too. The bottom line for this is that you don’t need to memorize every single chemical reaction that occurs in it; Typically AP books note that there are never questions on the exam about, say, acetyl coenzyme A or any of those other complicated sorts of things :P</p>
<p>However, you need a very strong understanding of the process and what allows it to happen, chemiosmosis and all of that fancy stuff. IF you don’t get that, I recommend you read the chapter on it really carefully, and if that doesn’t work try reading multiple sources on it. Often if I had trouble with a topic I’d go and read the description of it in multiple books and I’d be able to connect all of the information into one coherent explanation.</p>

<p>These are invaluable.</p>
<p>I have not taken AP Bio, but I took an introductory Bio course at a university this summer. The main thing to know about cellular respiration is that it is basically the oxidation of glucose taken out in many steps. Know about coupling reactions, using exergonic reactions to drive endergonic reactions, the three main parts (glycolysis, Krebs/citric acid cycle, electron transport chain). The most ATP is produced during chemiosmosis (also oxidative phosphorylation). Also know about phosphorylation and the structure of ATP. ATP is an unstable molecule and carries the most energy in the between the second and third phosphate group. ATP is produced in oxidative phosphorylation because the electron transport chain provides energy to establish a proton gradient across the inner membrane. The protons then flow back through the gradient while going through the ATP synthase which provides energy to phosphorylate ADP into ATP. During the Krebs cycle, remember that oxaloacetate is regenerated, which allows the cycle to continue.
I hope this helps. Good luck!</p>
<p>As michaelwiggins said, the most important thing is getting the gist of it, the overall purpose, function, and mechanisms. A lot of the nitty gritty details in the Campbell’s book can be really confusing, and unnecessary!
For cell respiration, I did what it looks like you’re doing and read a lot of different test prep books to understand it in simpler terms.
Also, does your Campbell’s book come with a CD? The CD has links to animations and things that really help, (the links are also in the review sections at the end of the chapter, under Media) but you’ll need an access code that you might have to get from your teacher. Those really helped me to visualize it. Good luck! :)</p>
