Basic Chemistry (part two) Flashcards
(24 cards)
Enzyme
proteinaceous catalysts that increase the rate of chemical reactions by lowering the activation energy
Activation energy
minimum energy reactants must have to start a reaction
Inorganic energy
substances that do not contain carbon
Organic energy
substances that contain carbon
Biochemistry
substances that are biologically active
Cohesion
the attraction of water molecules to other water molecules
Adhesion
attractive force of hydrogen bonds of water attracting other molecules
Specific heat
a large amount of heat required to raise the temperature of water
Mixture
substances that are only physically combined
Solution
mixture of anything that is chemically combined
Suspension
the separation of materials unless stirred
Colloid
dispersal of tiny particles in a medium
Solvent
what dissolves the solute
Solute
what is being dissolved in the solvent
Concentration
measure of number of particles of solute per volume of solution
Osmoality
reflects the number of particles dissolved in one kilo of water
Osmole
Avogrado’s number of particles in one kilogram of water
Acid
a proton donor or any substance that releases hydrogen bonds
Base
any substance that binds or accepts hydrogen ions
Salt
a compound consisting of a cation other than a hydrogen ion
Buffer
a solution of a conjugate acid-base pair
pH
hydrogen ion concentration in a solution
Carbohydrate
consists of C, H, and O
Lipid
composed of C, H, and O
