Enzyme Practice Questions

Front

What is the definition of a parasitic relationship?

Back

A parasitic relationship is one in which one organism benefits at the expense of another, often harming the host organism.

Front

What is the optimum pH for enzyme activity?

Back

The optimum pH is the pH level at which an enzyme is most active and efficient in catalyzing a reaction.

Front

What happens to an enzyme when its shape changes?

Back

If the shape of an enzyme changes, it may no longer be able to bind to its substrate, thus losing its ability to catalyze the reaction.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process by which an enzyme loses its three-dimensional structure due to extreme conditions, such as high temperature or pH, leading to loss of function.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme's activity is highest.

Front

What is a substrate in enzymatic reactions?

Back

A substrate is the specific reactant that an enzyme acts upon during a chemical reaction.

Front

How do environmental factors affect enzyme activity?

Back

Environmental factors such as temperature and pH can influence the shape and activity of enzymes, affecting their ability to catalyze reactions.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts that speed up chemical reactions in biological systems without being consumed in the process.

Front

What is the significance of enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to select and bind to a specific substrate, ensuring that only particular reactions occur.

Front

What is the effect of high temperatures on enzyme function?

Back

High temperatures can lead to denaturation of enzymes, causing them to lose their functional shape and activity.
