Equilibrium - CORRECT ANSWER-The state in which a chemical reaction's rate of product
formation is equal to the rate of reactant formation
4 Properties of H2O - CORRECT ANSWER-1) Stabilizing Body Temperature
2) Protection
3) Facilitating Chemical Reactions
4) Transporting Substances
Carbohydrates - CORRECT ANSWER--Consist of monosaccharides
-Can be stored and broken down and used as an energy source
-2:1 ratio of H to O for each C atom
Monosaccharides - CORRECT ANSWER-Building block of carbs; forms longer chains of carbs
,Disaccharides - CORRECT ANSWER--2 sugars
- 2 monosaccharides are joined by a covalent bond
Polysaccharides - CORRECT ANSWER--Many monosaccharides bound in long chains
-Glycogen, cellulose
Lipids - CORRECT ANSWER--Consists of glycerol and fatty acids; hydroxyl and carboxyl groups
-Only dissolves in nonpolar solvents
-Organic; composes of phosphorus and nitrogen
-Stores energy
Triglycerides - CORRECT ANSWER-Most common type of fat molecule
Saturated Fatty Acids - CORRECT ANSWER-Contains only single covalent bonds between carbon
atoms
Unsaturated Fatty Acids - CORRECT ANSWER-Has 1+ double covalent bonds
-Monosaturated
-Polyunsaturated
,Trans Fatty Acids - CORRECT ANSWER-Unsaturated fats that have been chemically altered by the
addition of H atoms
Phospholipids - CORRECT ANSWER--Component of cell structure and membrane
-Hounded to a phosphorus containing molecule instead of glycerol
-Has a hydrophobic and hydrophilic end
Eicosanoids - CORRECT ANSWER-regulatory molecules
Denaturation - CORRECT ANSWER-Broken hydrogen bonds in the protein; cannot maintain
shape
Enzymes - CORRECT ANSWER-Protein catalyst; increases the rate of chemical rxn by lowering
the activation energy
lock-and-key model - CORRECT ANSWER-Can quickly join amino acids to synthesis a protein;
after the reaction is finished the enzyme is released and can be used again.
Facts that Affect Rate of Chemical Rxn - CORRECT ANSWER-1) Different reactants have different
abilities
2) greater the concentration of the reactant, the greater the rate
3) Environmental temperature effects molecular motion
, Nucleic Acids - CORRECT ANSWER--Has phosphorus and nitrogen
-Transferred from one generation of cells to the next
-Are made up from a series of nucleotides; is an organic molecule
-Has hydrogen bonds
Proteins - CORRECT ANSWER--Has oxygen and sulfur
-Obtainable from food
-Made from amino acids and bonded by H2 bonds
-Consists of an amine group and a carboxyl group
-Macronutrient
-Function depends on the protein molecule's structure
Nucleotides - CORRECT ANSWER-Building block of nucleic acids; composed of a
monosaccharide with a nitrogenous organic base and a phosphate group are attached
Deoxyribonucleic Acid (DNA) - CORRECT ANSWER--Genetic material of cells; copied from one
generation of cells to the next
-Determines the structure of proteins
