18
Water is a polar molecule.
Explain this statement. Describe
how water is able to dissolve salts
such as NaCl.
19 Water has a positive and a negative
pole. The positive (hydrogen) end
surrounds and attracts negative Clions. The negative (oxygen) end
attracts and surrounds positive Na+
ions.
20
What is an acid?
What is a base?
What is a buffer?
21
An acid – gives of hydrogen (H+)
ions in solution. Ex: HCl
A base – gives off hydroxide (OH-)
ions in solution. Ex: NaOH
A buffer – helps resist pH change
22

reaction. What substance is
represented by the letter X?
Dipeptide + X  amino acid + amino
acid
29
Dipeptide + X  amino acid +
amino acid

biomolecules. Which class of
biomolecule is not a polymer?
31
Monomer
Polymer
Monosaccharide
Polysaccharide
Nucleotide
Nucleic Acid
Amino Acid
Protein
Lipids are not polymers because they are
not made of repeating subunits. Fat is
composed of 1 glycerol and 3 fatty acids.
32
Give 2 examples of lipids, and 2
examples of nucleic acids.
33
Lipids: triglycerides (fats and
oils), waxes, steroids,
phospholipids

34
DNA is a polymer consisting of
repeating units known as _____.
There are 4 of these… name
them.
35
What are nucleotides?
A - Adenine, C - Cytosine,
G - Guanine, T - Thymine
36 Use the following words to
completely describe the
structure of a DNA molecule:
Sugar/phosphate
Nucleotide
Nitrogenous base
Hydrogen bond
Double helix
37 DNA is 2 long chains of
nucleotides, twisted together in
a double helix. Each chain
consists of a sugar/phosphate
backbone, and nitrogenous
bases. The 2 strands of DNA
are held together by hydrogen
bonds between the nitrogenous
bases.
38
What type of
lipids are
represented in
this picture?
Describe the parts of the molecules
above in terms of being
hydrophobic and hydrophilic.
39
Non-polar
(hydrophobic)
fatty acid tail
Polar
(hydrophilic)
head
What are phospholipids?
40
DNA codes for traits in organisms.
Specifically describe how a
molecule of DNA is translated into
an organism’s traits.
41
DNA codes for proteins.
Sequence of nucleotide bases
determines the sequence of
amino acids in the polypeptide
chain. Sequence of a.a.
determines protein folding and
shape, which determines
function.
42
Movement of water molecules
from areas of high
concentration to areas of low
concentration.
43
What is osmosis?
44
The point at which molecules
are evenly distributed, and
diffusion stops.
45
What is equilibrium?
46
2 Factors that affect the rate of diffusion.
47
What is temperature, pressure,
concentration.
48

that water moved ________
(into/out of) the cells. What type
of solution is the salt water?
49
What is out of the cell, a
hypertonic solution.
