Biochemistry which of the following is not true about the peptide bond formation reaction? a) generates one molecule of atp b) releases a water molecule c) is a condensation or dehydration reaction d) links the carboxyl group of one amino acid to the amino group of another amino acid e) happens in the ribosome

A) Generates one molecule of ATP

Explanation:

Peptide bond formation is not an exergonic process and does not release the energy to support the process of ATP synthesis. Rather, activation of amino acids to attach them to their respective tRNAs during protein synthesis requires ATPs as an energy source. The reaction is catalyzed by aminoacyl-tRNA synthase.

The formation of the first peptide bond between the first two amino acids consumes GTP as an energy source.

Two successive amino acids are joined together by a peptide bond which is formed by removal of one water molecule from the alpha carboxyl group of one amino acid and alpha-amino group of another amino acid.

Since the reaction joins two amino acids together while releasing one water molecule, it is a condensation reaction.

dna is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).
