An endergonic reaction is a chemical reaction that requires an input of energy to proceed. These reactions are non-spontaneous and have a positive Gibbs free energy change.
5 Must Know Facts For Your Next Test
Endergonic reactions require the absorption of energy from their surroundings.
They are characterized by a positive change in Gibbs free energy (ΔG > 0).
In microbial metabolism, these reactions often involve anabolic processes, such as the synthesis of macromolecules.
ATP hydrolysis can be coupled with endergonic reactions to make them energetically favorable.
Endergonic reactions are typically associated with biosynthetic pathways in microorganisms.
