The shape of a protein molecule is influenced by

The answer is C. its sequence of amino acids.

The protein's shape is influenced by its sequence of amino acids or primary structure.

Explanation:

The primary structure of a protein molecule is dependent on the amino acid chain sequence it has. The amino acid chain's linear structure is composed of covalently bonded amino acids via peptide bonds. This serves as the overall backbone of the protein.

Secondary structure of protein

It defines the 3-dimensional shape of the locally folded polypeptide. They come in two forms, the alpha helices and beta sheets. During the formation of the primary structure, acidic and basic amino residues may cause kinks and turns, re-configuring the 3-D shape of the local polypeptide.

Tertiary structure of protein

This determines the overall 3-dimensional structure of the protein. The structure is due to the linking of the R groups of the related amino acids, hydrophobic bonds, and disulfide bonds. These bonds are highly stable and are not easily changed or destroyed.

Quaternary structure of protein

It is a structure that consists of multiple folded polypeptide chains or subunits. This allows the protein to have multiple functions. Non-covalent forces keep these structures together, making it prone to rapid conformational changes.
