7832859312anabolicconstructive metabolism; the synthesis in living organisms of more complex substances from simpler ones (opposed to catabolism ).0
7832863451catabolicdestructive metabolism; the breaking down in living organisms of more complex substances into simpler ones, with the release of energy (opposed to anabolism ).1
7832890097first law of thermodynamicsEnergy can be transferred or transformed, but never created or destroyed.2
7832920944second law of thermodynamicsstates that the total entropy can never decrease over time for an isolated system, meaning - a system which neither energy nor matter can enter or leave. The total entropy can remain constant in ideal cases where the system is in a steady state (equilibrium). In all other real cases, the total entropy always increases and the process is irreversible.3

7851203549over nourishmentOvernutrition or hyperalimentation is a form of malnutrition in which the intake of nutrients is oversupplied. The amount of nutrients exceeds the amount required for normal growth, development, and metabolism.9
7851210123malnutritionlack of proper nutrition, caused by not having enough to eat, not eating enough of the right things, or being unable to use the food that one does eat.10
