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.
An exergonic reaction will release energy from the reaction, while an endergonic reaction will absorb free energy from its surroundings. In order for an endergonic reaction to go to completion it needs an outside source of energy. In the cell this energy source comes from the chemical compound ATP. ATP helps the cell carry on 3 main types of work. Mechanical ( cell movement), chemical ( anabolism ), and transport ( pumping materials into and out of the cell ).
