Hey,

So that's my question any help would be appreciated.

Thanks

Do a google search for how enzymes work (or look in your text book) and you should be able to work this out.
Look out for the lock-and-key model and the induced-fit model

That should be enough for starting research. If you still have questions after researching OP then come back here with them.
Each enzyme has a specific amino acid sequence in its primary structure, which determines the enzyme's tertiary structure. This gives the enzyme an active site with a unique shape that is complementary to only a certain substrate, hence why it can only bind to that certain substrate.
