Proteins and Enzymes

Front

What are proteins?

Back

Proteins are large, complex molecules made up of amino acids that perform a variety of functions in the body, including building tissues, acting as enzymes, and supporting immune function.

Front

What are enzymes?

Back

Enzymes are specialized proteins that act as catalysts to speed up chemical reactions in the body without being consumed in the process.

Front

What is the primary structure of a protein?

Back

The primary structure of a protein is the unique sequence of amino acids that make up the protein chain.

Front

What is denaturation?

Back

Denaturation is the process by which a protein loses its native structure due to external factors such as heat or pH changes, leading to a loss of function.

Front

What factors can affect enzyme activity?

Back

Enzyme activity can be affected by temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme functions most efficiently, often around 30°C for many human enzymes.

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.

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can become denatured, meaning their shape changes and they can no longer function properly.

Front

What are amino acids?

Back

Amino acids are organic compounds that serve as the building blocks of proteins, consisting of an amino group, a carboxyl group, and a unique side chain.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes lower the activation energy required for biochemical reactions, allowing them to occur more quickly and efficiently.
