HB Lipids, Proteins & Nucleic Acids

Front

What is the primary sequence of a protein?

Back

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

Front

Can the structure of proteins be changed by environmental factors?

Back

True, the structure of proteins can be altered by changes in temperature or pH.

Front

What is a long chain of amino acids called?

Back

A long chain of amino acids is called a polypeptide.

Front

What type of protein structure do alpha helix and beta sheet represent?

Back

Alpha helix and beta sheet are examples of secondary protein structure.

Front

What is the secondary structure of a protein?

Back

The secondary structure of a protein is formed by hydrogen bonds creating alpha helices and beta pleated sheets.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

What is the role of hydrogen bonds in protein structure?

Back

Hydrogen bonds help stabilize the secondary structure of proteins, such as alpha helices and beta sheets.

Front

What is the difference between primary and secondary protein structure?

Back

Primary structure refers to the sequence of amino acids, while secondary structure refers to the local folding patterns like alpha helices and beta sheets.

Front

What is a tertiary structure in proteins?

Back

Tertiary structure is the overall three-dimensional shape of a protein, formed by the interactions between the side chains of amino acids.

Front

What is quaternary structure in proteins?

Back

Quaternary structure refers to the assembly of multiple polypeptide chains into a single functional protein.
