Factors that Effect Enzyme Reactions

Front

What are the main factors that affect enzyme activity?

Back

High temperature and pH levels.

Front

What is the optimum temperature for enzyme action?

Back

Approximately 37°C.

Front

Which enzyme's activity decreases in both acidic and basic environments?

Back

Chymotrypsin.

Front

Why does enzyme activity decline at high temperatures?

Back

Enzymes denature, changing the shape of the active site.

Front

What is the term for the pH at which an enzyme is most efficient?

Back

Optimum pH.

Front

What happens to enzymes at low temperatures?

Back

Enzyme activity decreases due to reduced molecular movement.

Front

How does pH affect enzyme activity?

Back

Each enzyme has an optimum pH; deviations can lead to decreased activity or denaturation.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where enzymes lose their functional shape, affecting their activity.

Front

What is the role of the active site in enzyme function?

Back

The active site is where substrate molecules bind and undergo a chemical reaction.

Front

How does substrate concentration affect enzyme activity?

Back

Increasing substrate concentration increases enzyme activity until a saturation point is reached.
