AP Biology - Unit 1 Review

Front

What is the main bonding in the secondary structure of a protein?

Back

Hydrogen bonding.

Front

What happens to a hydrophobic amino acid sequence when placed in water?

Back

The amino acids will bunch up.

Front

What is the term for multiple, fully folded protein chains interacting with each other?

Back

Quaternary structure.

Front

What primarily causes the folding in the tertiary structure of proteins?

Back

Interactions of the 'R' groups.

Front

What gives a protein its unique shape?

Back

The unique sequence of amino acids in its polypeptide chain, the unique folding due to the sequence of amino acids, and hydrogen bonding & unique interactions between the 'R' groups.

Front

Define primary structure in proteins.

Back

The unique sequence of amino acids in a polypeptide chain.

Front

Define secondary structure in proteins.

Back

The local folding of the polypeptide chain into structures such as alpha helices and beta sheets, primarily stabilized by hydrogen bonds.

Front

What is tertiary structure in proteins?

Back

The overall three-dimensional shape of a polypeptide, determined by interactions among the 'R' groups.

Front

What role do 'R' groups play in protein structure?

Back

They determine the interactions that lead to the folding and stability of the protein.

Front

What is the significance of hydrophobic interactions in protein folding?

Back

Hydrophobic amino acids tend to cluster together away from water, influencing the overall shape of the protein.
