Enzymes

Front

What is an enzyme?

Back

A protein that acts as a catalyst to speed up chemical reactions in biological processes.

Front

What is the role of a substrate in enzyme activity?

Back

The substrate is the reactant that an enzyme acts upon to form a product.

Front

What is the enzyme-substrate complex?

Back

The temporary complex formed when an enzyme binds to its substrate.

Front

What factors affect enzyme activity?

Back

Temperature, pH, substrate concentration, and enzyme concentration.

Front

What is the optimal temperature for enzyme activity?

Back

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

Front

How do enzymes speed up chemical reactions?

Back

By lowering the activation energy required for the reaction to occur.

Front

What does it mean for an enzyme to be specific to a substrate?

Back

It means that the enzyme can only catalyze a reaction for a particular substrate due to its unique shape.

Front

What happens to an enzyme after it catalyzes a reaction?

Back

The enzyme is not consumed in the reaction and can be reused for subsequent reactions.

Front

What is denaturation in relation to enzymes?

Back

The process in which an enzyme loses its shape and functionality due to extreme conditions, such as high temperature or pH.

Front

What are the main types of enzymes?

Back

There are several types, including hydrolases, oxidoreductases, transferases, and ligases.
