contents of enzymes?

Answer 1

A very complex array. A simple explanation that I was able to find is located in the links in this site.

Answer 2

Enzymes are molecules that make reactions happen faster. Most of the ones you hear about are made of proteins, although there are also enzymes made out of RNA and even DNA! The protein enzymes are made up of a chain of amino acids (think of beads on a string) which then fold up into a special shape. This special shape is made to do atleast one or two of the following: bring the reactants (those are the things that are taking part in your reaction of interest) together, position the reactants in a special way to make the reaction more likely, create a "mini-environment" around the reaction that is favorable, supply special chemical groups that make the reaction easier, or put stress or tension on a bond that you want to break. Well, atleast that is a good start. Some times enzymes have other things with them called cofactors that make them work better - sometimes it is a metal ion or a little molecule that is found in the cell. Hope this helps!

Answer 3

Enzymes are proteins, and may have cofactors which may be free or bound covalently or noncovalently.

Answer 4

cofactor?
substrate?
co-enzyme?
