MacromoleculesPut your names at the bottom of your boardDraw a box in the upper right corner to keep
scoreQuietly write your answer on the white board
and keep it from roaming eyesWhen I say- hold your board up for me to
review (if you are still writing after I say then your answer does not count)
Keep your own score- each question = 1 point unless otherwise instructed
Cheating will result in -5 on the actual assessment
1st place= +2; 2nd place = +1; 3rd place = +1
What are the 3 elements that are common in all ORGANIC substances?
Carbon, Hydrogen, Oxygen
How many chemical bonds can Carbon make with other elements?
four
What is the name of the process by which water is removed and
monomers are combined to form polymers?
Dehydration synthesis
Name a monomer of a carbohydrate.
Monosaccharide (either glucose, galactose,
fructose)
Name a macromolecule that can be used to provide energy for the human
body.
Carbohydrate or Lipid
Look at the image below. What type of macromolecule is pictured here?
Lipid (triglyceride)
2 point question:What are the two types of molecules that make up the molecule pictured
here:
Glycerol and fatty acid chains
Look at the fatty acid chains pictured. Are these fatty acids saturated or
unsaturated?
Saturated
List one characteristic of an unsaturated fat.
Double bonds within the carbon chainLiquid at Room TemperatureBent carbon chains“better” for you in diet
Provide on example of a food that contains saturated fat.
Meat, dairy….anything from an animal
Look at the image below. What is the name of this type of
monomer?
Nucleotide
Look at the image below. 3 points: Name the three parts of a
nucleotide.
Phosphate group, sugar, nitrogenous base
Which of the following polysaccharides is found in plants and
is used for storage in roots?STARCH, GLYCOGEN, CELLULOSE
STARCH
Which of the following polysaccharides is found in animals in
liver/muscles?STARCH, GLYCOGEN, CELLULOSE
GLYCOGEN
Which of the following polysaccharides can be broken down and used as energy for animals? (2
points for 2 answers)
STARCH, GLYCOGEN, CELLULOSE
STARCH & GLYCOGEN
The picture below is the monomer of proteins. What is it called?
Amino acid
If you wanted to break the peptide bond below, what process would you
have to do?
Hydrolysis
Which two macromolecule groups contain nitrogen? (2 points)
LIPIDS CARBOHYDRATES PROTEINS NUCLEIC ACIDS
Proteins & Nucleic Acids
What type of protein is used as a catalyst to speed up chemical
reactions?
An enzyme
2 points: Name 2 differences (be specific)
between DNA and RNA
DNA= deoxyribose, RNA= ribose
DNA= 2 strands, RNA = 1 strand
DNA= thymine, RNA = uracil
Why are nucleic acids important?
They determine who you are and what proteins your body
needs to make.
Look at the diagram of a phospholipid below. Draw how these would be
arranged if you found them in a cell membrane.
The function of a protein is dependent upon its shape.
What level of structure is pictured below?
Tertiary structure
When a protein changes shape and no longer works it is called
denaturing. List 2 things that can cause denaturation to occur. (2
points)
Drastic change in pHDrastic change in
temperatureUV light
What molecule is pictured below?
DNA (deoxyribonucleic acid)or
Nucleic acid
What kind of bonds hold the two strands in DNA together (between 2
base pairs)?
Hydrogen bonds
Using the letters A,C,U,G pair them up to show which bases will pair
together.
A—UG—C
If the nitrogenous bases found in a string of nucleotides contain A,C,U,G would you be looking at a strand of
DNA or RNA?
RNA- because it contains uracil and DNA doesn’t have
uracil
What type of macromolecule is pictured below?
Lipid (cholesterol)
List 2 characteristics of this molecule.
-acts as a chemical messenger-precursor to sex hormones-hydrophobic, nonpolar-is a lipid
