MSG is mistakenly thought of as being high in sodium. However, MSG contains only one-third the amount of sodium as table salt (MSG contains about 12 percent sodium while table salt contains 39 percent sodium). Moreover, MSG represents a minor contribution to the overall sodium level of a typical diet.
Endergonic reactions. In an endergonic reaction the free energy of the initial state is lower than the free energy of the final state. This kind of reaction is not termed a spontaneous reaction. In order to go from the initial state to the final state a considerable amount of energy must be imparted to the system.
Ernest Z. An exergonic reaction is one in which #Î´G# increases, and an endergonic process is one in which #Î´G# decreases. #Î´G# is the energy that is available to do work. An example of an exergonic reaction that occurs in our body is cellular respiration. This reaction releases energy that the cell uses for its activities. The above value of #Î´G# is for the conditions found within a cell. The tabulated value of #Î´G^Â°# = -2870 kJ refers to standard conditions (1 atm, 25 Â°C).
