Metabolic System

metabolic system governs the chemical and physical changes that take place within the body that enable it to continue to grow and function.
Metabolism involves the breakdown of complex organic compounds within the body in order to generate energy for all bodily processes.
Metabolism generates energy for the synthesis of complex substances that form the tissues and organs.
During metabolism, organic compounds are broken down to provide heat and energy in the process called catabolism.
Simple molecules are also used to build more complex compounds like proteins for growth and repair of tissues as part of anabolism.
Many metabolic processes are facilitated by enzymes.
The overall speed at which an organism carries out its metabolic processes is termed its metabolic rate (or when the organism is at rest, its basal metabolic rate).
DNA (deoxyribonucleic acid): A double helix molecule that contains the genes that provide the blueprint for all of the structures and functions of a living being.
Gene: a fundamental unit of heredity
Metabolism: The physical and chemical processes of cells burning food to produce and use energy. Examples include digestion, elimination of waste, breathing, thermoregulation, muscular contraction, brain function, and circulation.
Mitochondria: The part of the cell that is responsible for energy production. The mitochondria are also responsible for converting nutrients into energy and other specialized tasks.
Osteomalacia: softening of the bones
Osteopenia: low bone mass; deprivation of bone
Osteopetrosis: increased bone density
