    substrate does not increase the reaction rate. The line begins to level off and stay level at B on the graph. We call the maximum velocity of reaction. What happens is this, at first there is very little substrate and a lot of enzyme. An increase in the concentration of substrate means that more...

    Of course, enzyme concentration also affects the rate of reaction. This is my aim: to see to what extent this is true. If there are too many enzyme molecules, then there is unoccupied active sites- thus the rate of reaction would be great. As the ratio between the enzyme and the substrate becomes...
