In chemical thermodynamics, an exergonic reaction is a chemical reaction where the change in the free energy is negative (there is a net release of free energy). [1] This indicates a spontaneous reaction if the system is closed and initial and final temperatures are the same.
A net energy gain is achieved by expending less energy acquiring a source of energy than is contained in the source to be consumed. That is =. Factors to consider when calculating NEG is the type of energy, the way energy is used and acquired, and the methods used to store or transport the energy.
A classic example of this might be the first stage of a reaction which proceeds via a transition state. The process of getting to the top of the activation energy barrier to the transition state is endergonic. However, the reaction can proceed because having reached the transition state, it rapidly evolves via an exergonic process to the more ...

For example, when constructing an optimality model for bee foraging time, researchers looked at whether energetic efficiency (energy gained/energy spent) or net rate of gain ((energy gained − energy spent)/time) was optimized. It was found that the bees maximized energetic efficiency when foraging for nectar. [4]

For example, if you buy a house for $200,000 and the value goes up to $210,000, your basis is $200,000 and you have a $10,000 unrealized gain. If the value drops to $190,000, you have a $10,000 ...
The cycle does generate heat, and may be used to maintain thermal homeostasis, for example in the brown adipose tissue of young mammals, or to generate heat rapidly, for example in insect flight muscles and in hibernating animals during periodical arousal from torpor. It has been reported that the glucose metabolism substrate cycle is not a ...
