Question

Which statement best describes the molecular structure of protein, along with one of the functions of proteins?

Answer 1

Proteins are made up of amino acids and have four structural levels: primary, secondary, tertiary, and (optionally) quaternary. Their structures are closely related to their functions, which include roles as enzymes, structural components, and molecules involved in transport and regulatory processes.

Step-by-step explanation:

Protein Structure and Function

Proteins are essential macromolecules in living systems, comprising polymers of amino acids arranged in a linear sequence. The molecular structure of proteins includes several levels of organization, from the primary structure of a unique amino acid sequence to higher levels such as the secondary (alpha helices and beta-pleated sheets), tertiary (the overall three-dimensional structure), and quaternary structures (where multiple polypeptides combine).

Protein functions are diverse, including acting as enzymes, providing structural support, and playing roles in transport, metabolism, and cellular communication. The conformation of a protein is closely tied to its function, as it dictates the location and properties of functional groups, with each protein typically having a different and specific function.

Proteins have diverse functions such as being structural, regulatory, contractile, or protective. They may also be involved in transport, act as toxins, or function as enzymes. The structure of a protein greatly influences its function, with changes in shape leading to changes in functionality or even loss of function through denaturation.

Answer 2

I am not sure what the answer choices are for your question but I hope my answer helps.

Proteins are formed as chains of amino acids. Bonds within protein molecules will assist stabilize the structure. To add, the ending folded-forms of proteins can also be well adapted for the functions they consist of.
