MUSCLE PHYSIOLOGY

Detailed explanation-1: -A chemical reaction with a positive ∆G means that the products of the reaction have a higher free energy than the reactants (see the right panel of Figure 2). These chemical reactions are called endergonic reactions, and they are NOT spontaneous.

Detailed explanation-2: -Endergonic reactions A reaction forms weaker chemical bonds than a reaction that breaks chemical bonds. This leads to the system’s free energy increase. An endergonic reaction has a positive (greater than zero) change in Gibbs free energy (G). This decreases entropy (S).

Detailed explanation-3: -Reactions with a positive ∆G (∆G > 0), on the other hand, require an input of energy and are called endergonic reactions.

Detailed explanation-4: -Endergonic reactions are those that have a positive G value. Reactions that have negative G values are called exergonic reactions.

Detailed explanation-5: -Endergonic reactions are nonspontaneous. The progress of the reaction is shown by the line. The change of Gibbs free energy (G) during an endergonic reaction is a positive value because energy is gained (2).
