Please backing.. im stressed just about enzymes!?

Well i have this science report/coursework due in about enzymes and i cant find anything roughly speaking them that i could put in my own words as it all confuses me.

I need to put contained by it: what they are, their shape, how they work, what effects their activity and what are the best conditions they need.

And it says something roughly including pictures, key words, diagrams and graphs.

If anyone could help me by posting something they know which could help or any really willing websites then id be thankful as im really stressed in the region of all of the coursework which has been given to me to do over the weekend and in recent times need sleepto be honest!.
Thanks x

http://en.wikipedia.org/wiki/Enzymes for starters
and look for biology/ biochemistry textbooks on google books
or this textbook: http://www.ncbi.nlm.nih.gov/books/bv.fcg… and look at chapter 8 (enter it in the check out box to access)
I have an electronic biochemistry textbook on my computer. If you can manage to find an online copy of Lehninger Principles of Biochemistry or a Horton Biochemistry textbook online you will be biddable to go. It has a complete chapter on enzymes which would cover everything you need to know. Also I use http://www.youtube.com/watch?v=f7jRpniCs… http://www.youtube.com/watch?v=26ho8zCSo… http://www.youtube.com/watch?v=KCG5fDKr9… These are links to lectures on enzymes. Good luck beside your paper!
