Question

What provides the information necessary to specify the three-dimensional shape of a protein? Choose the best answer in the context of which generally applies to most proteins.

Choose one:
A. protein's interactions with other polypeptides
B. protein's peptide bonds
C. protein's interactions with urea
D. protein's interactions with molecular chaperones
E. protein's amino acid sequence

Answer 1

The three-dimensional shape of a protein is determined by its amino acid sequence, which influences how the protein folds and its final structure and function.

Step-by-step explanation:

The information necessary to specify the three-dimensional shape of a protein is provided by the protein's amino acid sequence. This sequence determines the unique way each protein folds into its final shape through various types of chemical interactions and bonds such as hydrogen bonds, ionic bonds, disulfide bridges, and hydrophobic interactions.

The tertiary structure is the overall three-dimensional structure of the protein, which is crucial for its functionality, and any alteration in shape can lead to protein denaturation and loss of function.
