i think it's the shape of the active site, the region where the enzyme comes into direct contact with the substrate. the shape of the active site is in turn determined by the structure of the enzyme, which is determined by the number and sequence of amino acids in the primary strucutre.(note that pH affects the shape of the active site as well.) just my guess.
Each enzyme has a characteristic shape
With a lot of heat, the enzyme will be denatured meaning it will lose its shape and therefore its function.
Because of the unique three-dimensional shape of the active site
A large number of reactions occur in the cell, many of which requiring enzymes to work. From the creation of the ATP used to energize the cell to the creation of proteins from RNA, each new type of reaction needs its own enzyme to work, and often need dozens if not hundreds of that enzyme to do the reaction at the pace it needs.

Each enzyme has a characteristic shape
All enzyme's are catalysts for certain chemical reactions. Each enzyme will only work with a certain substrate one analogy being that the enzyme is a key and the substrate is a keyhole, and each enzyme has a unique enzyme.
if a function has a unique y value for each x value the function is one to one.

Because of the unique three-dimensional shape of the active site
The structure is important because each enzyme's shapes allows only certain reactants to bind the enzyme.
Each enzyme has a characteristic shape
Each variable has an exponent equal to one.
each one has different patterns

The different number of electrons
Any function is a mapping from a domain to a codomain or range. Each element of the domain is mapped on to a unique element in the range by the function.
