Chapter 2: Problem 10

The tertiary structure of a protein is directly determined by a. genes. b. the primary structure of the protein. c. enzymes that "mold" the shape of the protein. d. the position of peptide bonds.

Short Answer

Expert verified
The correct answer is (b). The tertiary structure of a protein is directly determined by its primary structure (the amino acid sequence) within the polypeptide chain. The specific interactions among amino acids and their side chains lead to the folding of the protein molecule in a precise three-dimensional conformation, which is crucial for its stability and functionality.

Step by step solution

01

Understand protein structures

Proteins have four levels of structure: primary, secondary, tertiary, and quaternary. The primary structure is the sequence of amino acids in the polypeptide chain. Secondary structure refers to the formation of local structures such as alpha-helices or beta-sheets within the protein. Tertiary structure is the overall three-dimensional folding of the protein, and quaternary structure occurs when multiple polypeptide chains associate to form a complete protein complex.
02

Evaluate the choices

Now, let's evaluate each of the given choices: a. Genes encode for the primary structure of proteins (the amino acid sequence) but do not directly determine the tertiary structure. b. The primary structure of the protein (amino acid sequence) determines how the protein folds into its tertiary structure. c. Enzymes can facilitate the folding process for some proteins, but they don't "mold" the shape of the protein, the amino acid sequence does. d. The position of peptide bonds is essential for the primary and secondary structure, but not the tertiary structure directly.
03

Select the correct answer

Based on our evaluations, option b is the correct answer. The tertiary structure of a protein is directly determined by its primary structure, i.e., the amino acid sequence within the polypeptide chain. The specific interactions among amino acids and their side chains lead to the folding of the protein molecule in a precise three-dimensional conformation. This is important for its stability and functionality.
