entropy: the degree of disorder or randomness of a system.
environmental fitness: an individual's ability to adapt to an environment and reproduce.
enzymes: proteins that catalyze the chemical reactions within cells.

entropy The degree of disorder in a system. As energy is transferred from one form to another, some is lost as heat; as the energy decreases, the disorder in the system&emdash;and thus the entropy&emdash;increases.
