The joining of two amino acids via a peptide bond (the process of protein synthesis) has a positive $\Delta$G value. What does this imply?
A) Forming a peptide bond is endergonic and must be coupled to another reaction.
B) Forming a peptide bond is exergonic and must be coupled to another reaction.
C) Forming a peptide bond is spontaneous and does not need to be coupled to another reaction.
D) Forming a peptide bond is spontaneous and can sometimes be coupled to another reaction.
E) Forming a peptide bond increases the entropy of a system.

Question

Quizplus · Accepted Answer

A positive ΔG value indicates that the reaction (in this case, the formation of a peptide bond) is non-spontaneous or endergonic, meaning it requires an input of energy to proceed. This energy is typically provided by coupling the reaction to another process that releases energy, such as the hydrolysis of ATP.
