Most enzymes handle a substrate that is larger than an electron (with the exception of cytochromes!). In all these cases the space-filling needs of reactants and products are obviously different in the enzyme active site. the ronto group naplesWebbenzymes are proteins and serve as catalyst (anything that speeds up chemical reaction) an enzyme is protein catalyst enzymes are an evolutionary advantage that.
