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

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.
