Chapter 21, Problem 1STP

Interpretation Introduction

Interpretation: The correct option for the order or sequence of amino acids in the protein chain needs to be determined.

Concept Introduction:

Protein − proteins are composed of the different types of amino acids and they are bonded together with the help of the peptide bonds.

Based on the arrangement of the amino acids proteins classified into four structures, such as primary, secondary, tertiary and quaternary structure.

Answer to Problem 1STP

Correct answer: Option (A) primary structure.

Explanation of Solution

Reason for correct option:

The linearly arranged amino acids form the primary structure of the proteins. this simpler structure of the proteins.

Conclusion

Reasons for incorrect options:

Option (B) secondary structure of proteins is not the sequence of the amino acids, hence it is the incorrect option.

Option (C) tertiary structure of proteins is not the sequence of the amino acids, hence it is the incorrect option.

Option (D) polypeptide is not the sequence of the amino acids, hence it is the incorrect option.
