Barron's Bio E\M test ERRORS

<p>I had recently purchased the latest Barron's Bio book and I am quite disappointed. The book offers good information in an easy to learn way. There is one major glaring problem though, the book is often WRONG and convoluted. </p>

<p>Case 1: </p>

<p>Which is the following is the most important thing that occurs during cell respiration?</p>

<p>4 out of 5 of the answer choices are essential to the workings of cell respiration. </p>

<p>The book answer key however answers this question: "the purpose of cell respiration is to produce ATP. Therefore answer E is correct." </p>

<p>Am I wrong in saying this, but how in the world can this be the correct answer when 3 other ones are equally correct? Plus the book key doesn't even answer the question is answers a totally different one. </p>

<p>Case 2: Which of the following is correct about Glycolysis, krebs cycle, and the electron transport chain? </p>

<p>A: Glycolysis requires energy
B: Krebs cycle requires energy
C: Electron transport chain requires energy
D: Glycolysis depends on a gradient
E: Krebs cycles releases oxygen </p>

<p>The book key answer is A. That means C is wrong?? The transport chain creates a gradient, potential energy. How can energy be created without energy input?? That is saying the electron transport chain doesn't need any kind of energy and can go on forever?? </p>

<p>Case 3: The Calvin cycle occurs during light-dependent reactions. </p>

<p>This is obviously wrong and a typo. What makes it even more confusing is that the book key skirts on explanations! How hard is it to write a simple explanation for an answer? Instead I get this for case 3: "NADP gains hydrogen (is reduced to NADPH) during the light dependent reactions and carries the hydrogen to the Calvin cycle" obviously the Calvin cycle is in the independent reaction but just reading the answer makes it very unclear. </p>

<p>Case 4: Carotenoids absorb all colors of light EXCEPT</p>

<p>A: Green
B: Blue
C: Yellow
D: Red
E: Violet</p>

<p>Book answer key: C, yellow </p>

<p>Book explanation: Carotenoids are yellow, orange, and red and are responsible for the colors of carrots. Wait....RED??? You just told me it reflects only yellow!! :( </p>

<p>The worst part of it is that I am only on chapter 7 out of 18. Who knows how many more errors are out there???? Please, if anyone can offer explanations and can prove me wrong for any of these problems please do so!</p>

<p>Case 1) Without seeing the other options, I can’t comment on this.</p>

<p>Case 2) Good pickup, they should have said “requires ATP” instead of “requires energy”</p>

<p>Case 3) yup, typos happen. It’s only the 2nd edition, sometimes I see typos in a 7th ed!</p>

<p>you’re right about case 4. barrons makes a lot of typos/ errors, but usually they’re so obvious you don’t have to worry about it. I can help you with the rest if you can give the page numbers (i have the book)</p>

<p>I emailed barron’s about these questions and they replied back. Their answer…well it didn’t really answer my questions. They actually told me that there were more typos in the book and they gave me two corrections I didn’t even find lol. They answer questions I didn’t have and didn’t answer questions I did have. Oh well, try again next time I guess.</p>

<p>Holy shiz bro, they actually e-mailed you back!?!?!?!!</p>

<p>Man, I’m going to try e-mailing them now about the two Barron’s books I have. </p>

<p>–
Entering my soapbox:</p>

<p>Barron’s books should be burned. They are worthless for the APs. At least their AP Euro one was. </p>

<p>

<p>^Well, no one gets barrons for euro xD</p>
