Biochemistry & Enzyme Review

Front

What is the main function of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.

Front

How does pH affect enzyme activity?

Back

Different enzymes have optimal pH levels at which they function best; deviations can reduce their activity.

Front

What is the relationship between enzyme structure and function?

Back

The physical shape of an enzyme determines its ability to bind to substrates and catalyze reactions.

Front

What is dehydration synthesis?

Back

Dehydration synthesis is a chemical reaction that involves the formation of a bond between two molecules with the removal of water.

Front

What is hydrolysis?

Back

Hydrolysis is a chemical reaction that breaks down compounds by adding water.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without undergoing permanent change itself.

Front

What role do temperature and pH play in enzyme activity?

Back

Temperature and pH can affect the shape of enzymes, which in turn influences their activity and efficiency.

Front

What is the significance of maintaining homeostasis in relation to enzymes?

Back

Maintaining a constant internal environment ensures that enzymes can function optimally, as fluctuations can alter their shape and activity.

Front

What is the difference between an enzyme and a hormone?

Back

Enzymes are biological catalysts that speed up reactions, while hormones are signaling molecules that regulate physiological processes.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where substrate molecules bind and undergo a chemical reaction.
