Factors Affecting Enzyme Activity
Factors Affecting Enzyme Activity
Cellular Conditions
Misplacement or redistribution can reduce activity by separating enzymes from their substrates.
Enzymes often operate in specific cell locations.
Genetic Factors
Changes in enzyme shape affect its ability to bind to substrates, decreasing activity.
Mutations in the DNA coding for the enzyme can alter its structure.
Concentration
Enzyme and substrate concentrations that determine the rate of reaction.
Physical Structure of the Enzyme
Effect
Structural changes may block substrate access, decreasing enzyme activity.
The presence of specific shapes and structures at the active site.
Regulatory Molecules
Inhibitors, activators, and cofactors that modify enzyme activity.
Enviromental Factors
Cause
Factors like temperature and pH, which impact enzyme structure and function.
