Biochemistry TEST 2 2025- 2026 Review GRADED A+ QUESTIONS WIT H
CORRECT ANSWERS GRADED A+
biochemistry test
made of many smaller units called monomers
polymers
poly means
many
"really big" molecules made of smaller molecules
Macromolecules
small molecule or unit
building blocks of a macromolecule (polymer)
monomers
everything is made of
atoms
atoms that are chemically bonded together form __________
molecules
all living matter must contain carbon
organic matter
all living matter must contain _________
IT IS ESSENTIAL!!!!!!
carbon
four main types of organic matter
carbohydrates
lipids
proteins
nucleic acids
most common elements in organic matter
Carbon
Hydrogen
Oxygen
Nitrogen
Phosphate
Sulfur
when monomers are combined chemically, they join in a way that releases a
_________ ____________
water molecule
the process that releases a water molecule when monomers are chemically
combined
dehydration synthesis
making something by using water
process by which 2 or more monomers chemically bind to form polymers
dehydration synthesis
dehydration synthesis needs __________
enzymes
the process by which polymers are taken apart
during this process a water molecule is added
needs enzymes
hydrolysis
, Page 2 of 6
example of __________
sucrose + water --> glucose + fructose
hydrolysis
the LYSIS in hydrolysis means
break down/destroy
proteins that help chemical reactions take place in living things (catalyst)
enzymes
substance that increases the rate of a chemical reaction
catalyst
this is needed for dehydration synthesis and hydrolysis
enzymes
enzymes allow reaction to take place with ____________ energy at normal
temperatures
less
names of enzymes end in -ase _____________ breaks apart _______ (sugars
end in -ose)
sucrase
sucrose
lipids contain
Carbon
Hydrogen
Oxygen
lipids monomers
fatty acids
glycerol
lipids polymers
phosphides
fats
oils
waxes
steroids
lipids are _________ to all lipids
essential
long term energy storage in animals
provides insulation for animals
fats
all bonds between carbons are single so lots of hydrogens
saturated fatty acids
(saturated in hydrogens)
long term energy storage in plants
oils
unstable
one or more bonds between carbons are double or triple bonds
not as many hydrogens
unsaturated fatty acids
usually solid at room temperature
(lard or fat on steak)
saturated fatty acids
usually liquid at room temperature
(corn oil, peanut oil, canola oil, olive oil)
