Question

The shape of a protein is primarily determined by

a) type and sequence of amino acids
b) size
c) cell location

Answer 1

The shape of a protein is fundamentally determined by the type and sequence of its amino acids, which directly influence its function and unique three-dimensional structure.

Step-by-step explanation:

The shape of a protein is primarily determined by the type and sequence of amino acids. This sequence, known as the protein's primary structure, dictates how the protein will fold into its secondary and tertiary structures, and, if applicable, quaternary structure. The three-dimensional shape of a protein is critical for its function, just as specific utensils are needed for different types of food. The adjustments and folding driven by the amino acid sequence give each protein a unique shape and function after protein synthesis is complete.

Answer 2

The best answer is A.

The shape of a protein is determined by its primary structure. The primary structure is the sequence of amino acids in each polypeptide chain which make up a protein.

The sequence of amino acids is basically a list of amino acids that are linked to each other to form a chain which is known as a polypeptide chain.

The structure of the finished protein will depend largely on the first (primary) chain of amino acids to be produced to make up that protein.
