Noncompetitive inhibition and allosteric inhibition

Note: This is not a homework question. This is part of a study effort for a big test coming up soon. What's the difference between noncompetitive inhibition and allosteric inhibition????????? The progress I made on this problem: In Deborah Goldberg's AP Biology , "In noncompetitive inhibition, ...

Re: Pedigree problem

Your first batch of offspring tell you everything: it's sex-linked, or you wouldn't get traits in all females different from traits in all males; it's recessive, or your first generation females would show it. Thanks Darby!!!!!!!!!!!!!!!! I just have one question: But can you explain to me WHY woul...

Simple Protein Question

This is not a homework question: I was reading in Deborah Goldberg's AP Biology and when I was reading about the 1952 Hershey and Chase experiment, I got really confused. In the same book: "Proteins consist of the elements S[ulfur], P[hosphorus], C[arbon], O[xygen], H[ydrogen], and N[itrogen].&...

Re: Heme group question

Thanks for replying! Just making sure: My textbook lists heme and heme group as different entries. So they are still the same???? According to my textbook, a heme is a "Each subunit has a nonpolypeptide component, called heme, with an iron atom that binds oxygen." The definition does not i...

Re: Another biochemical question

Thanks blcr11 for the wonderful insight !!!!!!!! I just have a couple of questions: 1) What's a metal hydroxide? 2) How do you tell, just by looking at the molecular formula, that something is a metal hydroxide? 3) Does the fact that a molecule is a metal hydroxide mean automatically that it is a ba...

Re: A biochemical question

Thanks a lot, blcr11 !!!!!!!!! I just need to clarify up some points: 1) For the "catalyzing" part, I was thinking more about catabolism (as opposed to anabolism) and totally forgot about catalysts. 2) The problem starts out with the assumption of one enzyme - "In a lab experiment, on...

Another biochemical question

This question is also excerpted from Deborah Goldberg's AP Biology : "4. Which of the following is NOT a base? (a) NaOH (b) KOH (c) Mg(OH)2 [2 is the subscript to OH, but I can't type subscripts here] (d) C2H5OH (e) BaOH" Many lines, again, are skipped so that the reader can formulate his ...

Re: A biochemical question

Thanks a lot, blcr11 !!!!!!!!!!!!!!! So just to clarify: So are you saying that there are two possible interpretations , but based on the answers to the questions, you deduced that only one interpretation worked? If so, selection (2) was correct, right (because 1 would not work because as the soluti...

Thanks stopherlogic! :)

I'm sorry, but I just can't see the words "heme group" on the web page...
Are you sure wikipedia has heme group and not just heme????
