Enzyme Activity Modulation

Flashcards covering key concepts regarding factors that modulate enzyme activity.

Enzyme Activity

The rate at which an enzyme catalyzes a reaction, affected by environmental factors.

Factors affecting enzyme activity

Temperature, pH, and inhibitory molecules.

Brownian motion

Random movement of molecules that increases with temperature, enhancing enzyme-substrate interactions.

Optimal temperature

The temperature at which an enzyme operates most effectively before activity decreases.

Ectotherms

Organisms that regulate their body temperature based on the ambient environment, affecting enzyme activity.

Endotherms

Organisms that maintain a constant body temperature, minimizing the impact of external temperature on enzyme activity.

Denaturation

The loss of an enzyme's three-dimensional structure and activity due to high temperatures or extreme pH.

Inhibitory molecules

Chemicals that interact with enzymes and affect their catalytic activity.

pH

A measure of acidity or alkalinity that can influence enzyme structure and function.
