ULTIMATE AP Biology Exam Review |\ |\ |\ |\ |\
QUESTIONS WITH ANSWERS |\ |\
Define the following: isotope, valence shell, covalent
|\ |\ |\ |\ |\ |\ |\
bond, ionic bond - CORRECT ANSWERS ✔✔Isotope- one of
|\ |\ |\ |\ |\ |\ |\ |\
several atomic forms of an element, each with the same
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
# of protons, but different number of neutrons
|\ |\ |\ |\ |\ |\ |\
Valence shell- the outermost energy shell of an atom,
|\ |\ |\ |\ |\ |\ |\ |\ |\
containing valence electrons involved in chemical |\ |\ |\ |\ |\ |\
reactions
Covalent bond- bond where the electrons are shared
|\ |\ |\ |\ |\ |\ |\
Ionic bonds- a chemical bond resulting from the
|\ |\ |\ |\ |\ |\ |\ |\
attractions between oppositely charged ions |\ |\ |\ |\
Hydrogen bonds result in.... pH is... - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\
✔✔Hydrogen bonds result in a weak, polar, and covalent |\ |\ |\ |\ |\ |\ |\ |\ |\
bond between a H+ and a negative ion.
|\ |\ |\ |\ |\ |\ |\ |\
pH is the measure of hydrogen ion concentration
|\ |\ |\ |\ |\ |\ |\
,How many covalent bonds can carbon form? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔4 bonds |\ |\
Hydrogen bonds form between... - CORRECT ANSWERS |\ |\ |\ |\ |\ |\ |\
✔✔a H+ and a negative ion
|\ |\ |\ |\ |\
pH is a measure of.... What is a buffer? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔pH is a measure of ion concentration |\ |\ |\ |\ |\ |\ |\
A buffer minimizes the changes in a solution when acids
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
and bases are added
|\ |\ |\
What are the differences between catabolic and anabolic
|\ |\ |\ |\ |\ |\ |\ |\
reactions? - CORRECT ANSWERS ✔✔Catabolic reactions |\ |\ |\ |\ |\ |\
break down complex molecules and anabolic reactions
|\ |\ |\ |\ |\ |\ |\
build them up. |\ |\
What is an isomer? Define structural, geometric, and
|\ |\ |\ |\ |\ |\ |\ |\
stereoisomers? - CORRECT ANSWERS ✔✔An isomer is |\ |\ |\ |\ |\ |\ |\
when different compounds the same molecular formula
|\ |\ |\ |\ |\ |\ |\
but different structure. A structural isomer is an isomer
|\ |\ |\ |\ |\ |\ |\ |\ |\
that has different covalent arrangements of their atoms;
|\ |\ |\ |\ |\ |\ |\ |\
geometric isomers have the same covalent bonds but |\ |\ |\ |\ |\ |\ |\ |\
differ in spacial arrangment; enatimors mirror images of
|\ |\ |\ |\ |\ |\ |\ |\
each other |\
, Name the following functional groups: -OH -C=O -COOH -
|\ |\ |\ |\ |\ |\ |\ |\
NH2 -SH -OPO3 - CORRECT ANSWERS ✔✔Hydroxyl;
|\ |\ |\ |\ |\ |\ |\
carbonyl; carboxyl; amino; sulfhydryl; phosphate
|\ |\ |\ |\
What is the general formula for a monosaccharide?
|\ |\ |\ |\ |\ |\ |\
What is the function of monosaccharides?
|\ |\ |\ |\ |\
What are polysaccharides?
|\ |\
What are the differences between glycogen, starch,
|\ |\ |\ |\ |\ |\ |\
cellulose, and chitin? - CORRECT ANSWERS ✔✔C1H2O1
|\ |\ |\ |\ |\ |\
energy storage and structural support
|\ |\ |\ |\
Chain of monosaccarides
|\ |\
Starch (plants) and glycogen (animals) store energy in
|\ |\ |\ |\ |\ |\ |\ |\
carbohydrate form, whereas cellulose (plant wall) and |\ |\ |\ |\ |\ |\ |\
chitin (exoskeleton) provide structural support.
|\ |\ |\ |\
What are the structural components of fats,
|\ |\ |\ |\ |\ |\ |\
phospholipids, steroids? |\
Fats store....
|\
Phospholipids form.... |\
