2.4.5 Enzyme Activity: Enzyme Concentration

Enzyme Activity: Enzyme Concentration

  • Enzyme concentration affects the rate of reaction
  • The higher the enzyme concentration in a reaction mixture, the greater the number of active sites available and the greater the likelihood of enzyme-substrate complex formation
  • As long as there is sufficient substrate available, the initial rate of reaction increases linearly with enzyme concentration
  • If the amount of substrate is limited, at a certain point any further increase in enzyme concentration will not increase the reaction rate as the amount of substrate becomes a limiting factor
