enzymes and substrate....

[sallyfly27]

i have no background in science really, but have 1 module of it in uni, i need to talk about what

 

enzymes are, include about temperature, equilibrium, non-protein (conjugated proteins) and protein

 

ones (globular proteins), their structure (tertiary which is three dimensional).

 

say what they are used for and why the body needs them. and i genuinel dont have a clue can

 

then talk about how substrate can alter the rate of reaction.

 

anyone help??

Probably you should read up on basic info about enzymes and proteins, as it is too broad to cover in one or two posts. However, depending on what they told you and whether you accurately quoted it, it seems that you may be confusing things about protein and non-protein enzymes. Conjugated enzymes are still proteins, even if they are coupled to something else. Non-protein enzymes are required to be free of peptides or proteins. This include, for instance, ribozymes, which are made from nucleic acids.

 

Again, read up first on basics of proteins, then go to protein structures (including primary, secondary and tertiary structures). Enzymes are a subclass of proteins, which you should read up after that. And only after you got a grasp of it I would go to enzyme kinetics and equlibrium reactions.
