Life

a series of intricate, precisely timed chemical reactions

Bioenergetics

life depends on energy, and energy transfers to maintain the organization

Metabolism

the sum total of all of the chemical activities of the cell

Anabolism

chemical activities which build larger molecules into smaller ones

Catabolism

chemical activities which break down larger molecules into smaller ones

Kinetic energy

energy of movement

potential energy

energy of position

calorie

amount of energy needed to raise the temperature of one gram of water one degree celsius

oxidation

loss of electrons, gain of oxygen, loss of hydrogen

reduction

the gain of electrons, loss of oxygen, gain of hydrogen

First Law of Thermodynamics
