Factors Affecting Enzyme Activity
Enzymes are biological catalysts that are essential for numerous biochemical reactions in living organisms. Their activity can be influenced by various factors, including cellular conditions, physical structure, regulatory molecules, concentration, genetic factors, and environmental factors.

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.
