Factors affecting enzyme action

• what are examples of environmental conditions that can change the 3D structure of an enzyme molecule?

  • temperature
  • pH
• what happens when environmental conditions causes the 3D structure of an enzyme molecule to change?

  bonds are broken and the configuration of the active site is altered, changing the rate of the reaction
• how do the concentrations of the enzyme and substrate affect the rate of reaction?

  by changing the number of enzyme-substrate complexes formed
