Exergonic because they release more energy than they use

Exergonic because they use more energy than they release

Endergonic because they release more energy than they use

During transfer of energy, some is lost in a form that is unusable, such as heat energy.

Kinetic energy is efficiently converted into potential energy.

Once energy is lost, it reaches equilibrium.
