How Enzyme Concentration Affects Reation Rate


The graph shows that when a large excess of substrate is maintained, the reaction rate will increase as the concentration of enzymes is increased. This is a linear relationship.

An analogy to help explain this phenomenon would be an automobile factory. One assembly line can crank out a dozen or so cars a day. Two assembly lines might crank out two dozen cars a day. Three assembly lines might build 3 dozen cars a day and so on....

In this example, enzymes are like the auto assembly line. Just like the enzyme, the assembly line helps convert individual auto parts into a complete auto, and as the completed car leaves, they begin to build a new auto.
