Enzyme Review B

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed at the end of a chemical reaction.

Front

How does the shape of an enzyme relate to its function?

Back

The shape of the enzyme is specifically designed to fit certain substrates, allowing it to perform a specific reaction.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme works best, often around 30°C for many enzymes.

Front

What is the significance of the human body maintaining a temperature of around 98.6 degrees?

Back

This temperature is important because enzymes function best at specific temperatures, which is crucial for metabolic processes.

Front

What is the optimal pH for enzyme activity?

Back

The optimal pH is the pH level at which an enzyme is most active; for some enzymes, this is around pH 9.

Front

Define enzymes.

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms.

Front

What is a substrate in relation to enzymes?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What happens to enzymes at high temperatures?

Back

High temperatures can denature enzymes, altering their shape and rendering them inactive.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external stress, such as extreme temperature or pH.

Front

How do enzymes lower activation energy?

Back

Enzymes lower activation energy by providing an alternative reaction pathway, making it easier for the reaction to occur.
