Question

Which of the following is true regarding the formation of a peptide strand (aka forming primary structure). (Select all that are true)

a. ATP is used in this process to transform the OH on the carboxylic acid into a good leaving group.
b. The process does not need enzymes to occur
c. No ATP is needed, just enzymes.
d. The primary structure is formed from the coupling of an amine of one amino acid to the carboxylic acid of another.

Answer 1

The formation of a peptide strand, or primary structure of a protein, involves the coupling of amino acids through the formation of a peptide bond. Enzymes called aminoacyl-tRNA synthases are required for this process, but ATP is not needed. The answer is options C and D.

Step-by-step explanation:

The formation of a peptide strand, also known as the primary structure of a protein, involves the coupling of an amine group of one amino acid to the carboxylic acid group of another amino acid. This process occurs through the formation of a peptide bond, which is a covalent bond between the amino acids. No ATP is needed for the formation of the peptide bond. However, enzymes called aminoacyl-tRNA synthases are required to attach the appropriate amino acid to tRNA, which then interacts with the ribosome during translation to form the peptide strand.
