Organics are generally complex molecules, such as - macromolecules, vitamins,
neurotransmitters, hormones, and drugs
Organic elements make up ___ percent of body mass - 97
Most of the macromolecules in our body are - proteins (17% body mass) or lipids
(15%) body mass
Inorganics are generally ____ - salts. AKA: electrolytes. Don't forget that H2O is an
inorganic molecule
Major inorganic elements of the body include - Na+, K+, Ca2+, Cl-, and Mg2+ (all
together make up about 3% body mass)
