Answers
1
Which of these is NOT one of the three most common elements in organic compounds?
hydrogen
carbon
sulfur
oxygen
2
In which group would you find this monomer?
lipids
protein
Nucleic Acids
Lipids
3
What type of bond links carbon atoms together in long chains?
covalent
hydrogen
ionic
emotional
4
Lipids are used
storing genetic info
source of immediate energy
structural support
long term energy storage
5
Why is a water molecule polar?
H donates an electron to O because oxygen is more electronegative
there is an unequal sharing of electrons between the atoms
oxygen donates an electron to hydrogen
H and O have opposite charges and opposites attract
6
Which of the following water properties is most closely related to surface tension?
freezing and expansion
polarity
solubility
high specific heat
7
This is the monomer of which group of Macromolecules?
Nucleic Acids
Carbohydrates
Proteins
Lipids
8
Because water has high specific heat/heat capacity it
Is a good solvent
Acts as a buffer
Changes temperature slowly
Is less dense as a solid.
9
Which of the following is NOT a shape that carbon backbones take in organic chemistry?
quadruple bonds
branching
chains
cyclic/rings
10
Identify this functional group
Carbonyl
Carboxyl
Methyl
Amine
11
Which of water's properties is MOST closely related to ice floating in water?
water's ability as a solvent
surface tension between the water and the ice
distance between water molecules
high specific heat
12
Why do humans really need water?
So they won't become dehydrated.
To dissolve other molecules
Synthesis reactions
To provide energy to the body.
13
Who is this?
Zoe
Abby Cadabby
Prairie Dawn

Carbohydrate
Protein
Lipid
Nucleic Acid
18
You are lost and alone in a forest. Help is not coming. Which do you choose to eat and why?
Carbs: quick energy
Lipids: most energy per gram.
Lipids: 2nd source of energy
Carbs: provides 4 calories/g
19
Which of the following is NOT a reason that C is an ideal atom for a macromolecule backbone?
Can make chains, branches and cyclic structures
Easily bonds with SPONCH
Can make ionic bonds easily
Makes four bonds
