Proteins and Enzymes

Front

What is the primary function of proteins in the body?

Back

Proteins serve various functions including structure, transport, and catalyzing reactions, but they do NOT store genetic information.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes speed up biochemical reactions by lowering the activation energy required for the reaction to occur.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, essential for various bodily functions.

Front

How do enzymes affect the speed of reactions?

Back

Enzymes make reactions go faster and use less energy.

Front

What nutrient is primarily used to build and repair muscle?

Back

Protein is primarily used to build and repair muscle.

Front

What is the relationship between enzymes and activation energy?

Back

Enzymes lower the activation energy needed for a reaction, allowing it to proceed more quickly.

Front

Can proteins store genetic information?

Back

No, proteins do not store genetic information; that function is performed by nucleic acids like DNA.

Front

What are the four main types of biological macromolecules?

Back

The four main types are proteins, carbohydrates, lipids, and nucleic acids.

Front

What is a substrate in the context of enzymes?

Back

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

Front

What happens to enzymes after they catalyze a reaction?

Back

Enzymes are not consumed in the reaction and can be reused multiple times.
