Question Answer
Makes up ⅔ of all body mass and affects all systemsWater
Lubricates joints and other passageways (allows low friction and cushioning)Water
Ability to absorb heatHeat capacity
Has a high heat capacityWater
Uniform mixtures (physical combinations) of substancesSolutions
Medium in which other atoms ions, or molecules are dispersedSolvent
Dispersed substancesSolute
Solution in which water is the solvent Aqueous solution
Solution with medium-large solute particles, like proteins; often viscousColloid
Solution with very large particles that can settleSuspension
React with polar molecules and ionsWater
Hydrophilic because they interact well with waterPolar molecules and ionic compounds
Hydrophobic because they do not mix well with wellNonpolar molecules like fats and oils
Breakup of a solid ionic compound into its constituent ionsDissociation or ionization
Dissolved ions in solutionElectrolytes
Hydrogen ion concentration measuredpH
Acids release this when dissolved in waterHydrogen ions
Accept hydrogen ions in solutionBase
Ionic compounds that do not release either hydrogen ions or hydroxide ionsSalts
AcidosisLower blood pH (Can cause coma)
AlkalosisHigher blood pH (Can cause uncontrollable muscle contractions)
Used to regulate pHBuffers
All molecules that can be synthesized or broken down by chemical reactions in the bodyMetabolities
Essential metabolities normally obtained by dietNutrients
Sugars, fats, and protiensOrganic compounds
Carbon dioxide, oxygen, water, acids, bases, and saltsInorganic compounds
Carbon, hydrogen, and oxygen 1:2:1 ratioCarbs
Most important metabolic fuelGlucose
Polysaccharide stored in the liver and muscles (can break down into individual glucose molecules)Glycogen
Plant-made polysaccharidesStarches
