The substrate is the molecule that
reacts inis formed by
Increasing the substrate concentration
decreasesincreasesdoes not effect
the rate of reaction. This is because more substrate molecules will be
with enzyme molecules, so more product will be formed.
However, after a certain concentration any increase will have
a lota littelNo
effect on the rate of reaction, since
concentration will no longer be the
factor. The enzymes will effectively become
, and will be working at their maximum possible rate. The rate of reaction will not be able to increase any further.
