and Answers| Latest Update
Kinetic energy Energy resulting from the movement of an object
Activation energy Minimum energy that the reactants must have to start a chemical
reaction
Enzymes Catalysts that lower the activation energy
Water Stabilizes body temperature, protects against friction and trauma, makes chemical
reactions possible, directly participates in chemical reactions, and is a mixing medium
Mixture Combination of two or more substances physically blended together
Solution Any liquid, gas, or solid in which the substances are uniformly distributed with
no clear boundary
Solute Dissolves in the solvent
Solvent Substance in which the solute dissolves
Acids Proton donors; less than 7pH
, Bases Proton acceptors; more than 7pH
Neutral solution 7pH
Buffer Solution of a conjugate acid-base pair that resists changes in pH when acids or
bases are added to the solution
Monosaccharides Basic building blocks of other carbohydrates
Disaccharides Formed by dehydration reactions between two monosaccharides
Polysaccharide Composed of many monosaccharides bound together to form a long chain
Triglycerides Composed of glycerol and fatty acids
Phospholipids Lipids in which fatty acid is replaced by a phosphate-containing molecule
Steroids Lipids composed of four interconnected ring molecules
Proteins Composed of amino acids
