Back

Hemoglobin transports oxygen from the lungs to the body's tissues and carries carbon dioxide back to the lungs for exhalation.

Front

What are proteins?

Back

Proteins are macromolecules made up of amino acids that perform a variety of functions including structural support, catalyzing biochemical reactions, and transporting molecules.

Front

What is the monomer of proteins?

Back

Amino acids are the building blocks (monomers) of proteins.

Front

What does the primary structure of a protein refer to?

Back

The primary structure of a protein refers to the specific sequence of amino acids in the polypeptide chain.

Front

What type of reaction is used to break down proteins into amino acids?

Back

Hydrolysis is the reaction used to digest and break the bonds in proteins.

Front

What are the two main types of protein structures?

Back

The two main types of protein structures are fibrous proteins (structural) and globular proteins (functional).

Front

What role do enzymes play in biological systems?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.

Front

What is denaturation in proteins?

Back

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

Front

What is the significance of the R group in amino acids?

Back

The R group (side chain) of an amino acid determines its properties and role in protein structure and function.

Front

What is the difference between essential and non-essential amino acids?

Back

Essential amino acids cannot be synthesized by the body and must be obtained from the diet, while non-essential amino acids can be produced by the body.
