Biology/Kerbs cycle

Question
I am a high school science teacher and I had an excellent text that showed the conversion or entry point for proteins and lipids into the kerbs cycle would you happen to know where I can get another copy online or in a text?
Thanks for using AllExperts. Good examples of Krebs cycle diagrams can be found in the book Rapid Review: Biochemistry by Pelley and Goljan. This text is actually a review book for the medical licensing exam, and it has a very concise and thorough chapter on the Krebs cycle. I might also recommend a text called Lippincott's Illustrated Reviews: Biochemistry by Champe, Harvey, and Ferrier. It is a longer text, though still primarily oriented toward review, with good overviews of all the major biochemical processes.
Online, there is a complete diagram here:

Unfortunately, the enzymes are not named directly on this diagram--they are described with a standard numbering system used for that purpose (the Enzyme Commission number). For instance, the enzyme 6.4.1.1 that converts pyruvate into oxaloacetate is pyruvate decarboxylase. It is entirely possible to look up all the EC numbers and reference them with the actual enzyme names. You can do that here:

You may also wish to try this diagram: http://www.sigmaaldrich.com/etc/medialib/docs/Sigma/General_Information/2/ee_min... If the link does not work, try a Google search for "anaplerotic reactions" and select the third or fourth link. Good luck!

Expertise
I will answer all biology-related questions through the undergraduate level. I will explain unclear concepts and suggest approaches to solving problems, but would prefer not to completely solve homework problems for you. If you are completely stumped on homework, tell me what you already know and I will help you as much as possible. Please do not ask me for ideas on school research projects; part of research is determining a suitable area of investigation, and that's not a task that should be completed by someone else. Please don't simply send me your homework for solutions. If you are having difficulty after you have started an analysis, I will be happy to direct your thinking; in particular, I would prefer to not simply solve pedigrees for students, but I will be happy to assist in solving pedigrees that you have already started. If you don't understand how to analyze a pedigree, I'd highly recommend watching this video, in which a biology professor explains the basic concepts of pedigree analysis: http://www.youtube.com/watch?v=HbIHjsn5cHo
