Science and enzymes and yea

Question

Explain what would happen if a reactant molecule with a different shape to the enzyme came in contact with the enzymes active site

 

 

I need need the answer ASAP 

thanks dudes 

Answer 1

The active site amino acid side chain electrons and protons that normally "prepare" the reactant, than then "attack" the reactant would be stereochemically in the wrong positions to do so.  As a result the reactant would either not be "attacked" at all, or "attacked" inefficiently.  A less likely scenario is that the enzyme would attack the reactant, and form the "wrong" product.
