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.
Exergonic reactions involve the formation of bonds; endergonic reactions involve the breaking of bonds. Exergonic reactions release energy; endergonic reactions absorb it. In exergonic reactions, the reactants have less chemical energy than the products; in endergonic reactions, the opposite is true. 54. Glucose molecules provide energy to power the swimming motion of sperm.
