Cards

Term
Ionic bonding
Definition
atoms exchange electrons
Term
Covalent bonding
Definition
2+ atoms share electron pairs
Term
Ion
Definition
charged particle (atom or molecule)
Term
Cation
Definition
positively charged particle
Term
Anion
Definition
negatively charged particle
Term
Physiological Saline
include names of solute and solvent
Definition
.9% NaCl (solute) in H2O (solvent)
Term
Three most prominent ions in body
Definition
Na+ Cl- & K+
Term
Polar covalent bond
give example
Definition
electrons are shared unevenly, creating partial charges.
(H2O, H's are more positive, O is more negative)
Term
How to find the molecular mass of Glucose
Definition
C6-H12-O6; multiply the atomic masses of C and O by 6, and the a.m. of H by 12, and find the sum.
Term
electrolyte
Definition
any substance containing dissociated ions which allows for electrical conduction
Term
anabolism
include purposes (3)
Definition
a metabolic reaction in which a substance is synthesized. Responsible for growth, maintenance, and repair.
Term
catabolism
Definition
a metabolic reaction in which a substance is broken down
Term
dehydration
Definition
a catabolic reaction through which water is produced (a -OH and a -H are removed, bonding the two molecules, and forming H2O)
Term
hydrolysis
Definition
catabolic reaction where water is used to break a bond. (given a -O- bond, an H is added to the O for one side, and the remaining -OH is added to the other).
Term
Oxidation
Definition
An atom/molecule loses an electron making it a cation (positively charged).
Mnemonic: OIL RIG (Ox. Is Loss, Red. Is Gain)
Term
Reduction
Definition
An atom gains an electron making it an anion (negatively charged).
Mnemonic: OIL RIG (Ox. Is Loss, Red. Is Gain)
Term
Oxidation-Reduction Reactions
Definition
Chemical reaction where the oxidation of one substances is coupled with the reduction of another
Term
Three things that effect rate ("speed") of reactions
Definition
1. Temperature 2. Concentration of reactants 3. Catalysts
Term
4 physiological uses of water
Definition
1. temperature stabilization 2. protection 3. chemical reactions 4. solvent
