    Enzymes
    All enzymes are bio-chemically classed as ----------------. By convention their names end in -----------. They speed up ------------------ reactions by lowering the --------------- ----------- Their tertiary structure results in them having a ----------------- shape, but more importantly determines the shape of the ------------- ----------- . It is in this region that the -------------- attaches. Two theories have been suggested to explain this relationship 1) Lock and Key 2) ------------- ----------. It is also sometimes necessary for an ------------- ----------------------- to attach first to make the correct shape.
    Many enzymes also work in conjunction with co-enzymes such as --------------------- and --------------------. Some substances such as cyanide act as enzyme ------------------.
    Enzymes are v. sensitive to temperature their rate of reaction usually doubles for each rise of --------- and this is known as ------. The ----------------- temperature for most plant enzymes is 25 degrees C– human enzymes operate best at -------- degrees C- some bacterial enzymes can operate at high temps 80-90 and are called --------------------enzymes but normally an enzyme would be ------------------------ at these temperatures. Enzyme activity also depends on suitable --------- .
