A good example of an endergonic reaction is photosynthesis.
5. Briefly describe how ATP is generated by chemiosmosis during the light-dependent reactions of photosynthesis.

Energy, exergonic reactions, and endergonic reactions.
Each antenna complex is able to trap light and transfer energy to a complex of chlorophyll molecules and proteins called the reaction center (see Fig. 1). As photons are absorbed by chlorophyll and accessory pigments, that energy is eventually transfered to the reaction center where, when absorbed by an excitable electron, moves it to a higher energy level. Here the electron may be accepted by an electron acceptor molecule of an electron transport chain (see Fig. 1) where the light energy is converted to chemical energy by chemiosmosis.
(Audio - Important) illustrates endergonic and exergonic reactions.
In an electron transport system, energy from electron transfer during oxidation-reduction reactions enables certain carriers to pump protons (H+) across a membrane. As the (H+) concentration increases on one side of the membrane, an electrochemical gradient called proton motive force develops. As the accumulating protons follow the electrochemical gradient back across the membrane through an ATP synthase complex, the movement of the protons provides energy for synthesizing ATP from ADP and phosphate.
The glycolytic pathway is an arrangement of these kinds of
coupled reactions, where exergonic steps push or pull endergonic steps, with the
favorable net free energy change of the steps taken together, allowing the
series of reactions to go on.
Distinguish between exergonic and endergonic reactions.
The exergonic light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH. These reactions occur in the thylakoids of the chloroplasts. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions.

This effect "orients" the water molecule in the field, and is the well-known "orientation factor" of electrochemistry which serves to catalyse the rate of oxygen dissociation from the water molecule, and thereby causes the reaction rate to proceed at the lowest energy levels.
