Question

proteins are complex carbon - based polymers made from amino acids. proteins have many different functions in living organisms.
determine whether each statement is true or false.

	true	false
all proteins have a quaternary structure.
some proteins are hormones that help regulate body processes.
the types of amino acids in a polypeptide influence the structure of a protein.

Explanation:

For "The structure of a protein impacts its function."

Protein structure (e.g., shape) determines its interaction with other molecules, thus affecting its function (e.g., enzymes' active sites).

For "All proteins have a quaternary structure."

Quaternary structure (multiple polypeptide chains) is only present in some proteins (e.g., hemoglobin), not all (e.g., myoglobin has only one chain).

For "Some proteins are hormones that help regulate body processes."

Examples like insulin (a protein hormone) regulate blood glucose, showing some proteins act as regulatory hormones.

For "The types of amino acids in a polypeptide influence the structure of a protein."

Answer:

True
