1
What are
macromolecules?
2
molecules that are made
from several smaller
molecules i.e. “giant
molecule”
3
All biomolecules are composed
of what main atom? Explain
why this is.
4
Carbon, has 4 valance electrons
5
What is a monomer?
Polymer? What is the
process called when you
put monomers together?
6
Mono – single unit
Poly – many small units
bonded together
Polymerization
7
What are the 4 types of
biomolecules that make up
living things? What does it
mean to be alive?
8
Carbohydrates, Lipids, Protein,
& Nucleic Acid
To respire, excrete, reproduce,
grow, react to environment,
keep homeostasis
9
What does it mean to be
soluble & insoluble in
water? Which biomolecule
is insoluble in water?
10
Soluble – able to mix
Insoluble – unable to mix;
Lipids
11
What is the main function
of carbohydrates? The
monomer of a
carbohydrate is the
___________.
12
Energy source, monosaccharide
13
What is the main function
of nucleic acid? The
monomer of a nucleic acid
is the ___________.
14
Pass on genetic code,
nucleotide
15
What is the main function
of lipids? The monomer of
a lipid is the ___________.
16
Energy storage & creates cell
membranes
Glycerol & fatty acid chains
17
What is the main function of
protein? The monomer of a
protein is the ___________.
18
Regulate all chemical
reactions (height, color,
size)
amino acid
19
Which of the biomolecules
looks like a helix? A ring of
carbon?
20
Nucleic acid; carbohydrate
21
What are the 3 main
monosaccharides? Which is
found in fruit? Milk? Candy?
22
Fructose -fruit
Galactose - milk
Glucose - candy
23
When eating a large bowl of
pasta what type of
carbohydrate are you
consuming? Is it a
monosaccharide, disaccharide
or polysaccharide?
24
Starch; polysaccharide
25
Explain why you obtain more
energy from pasta as opposed
to a piece of fruit.
26
Pasta is a polysaccharide
more bonds to break= more
energy
27
Give 2 examples of food that
contain saturated fat
& another 2 that contain
unsaturated fat.
What is the structure difference
between the two?
28
Saturated – unhealthy
Unsaturated – healthy
Double bonds in the fatty
acid tails (kinks) liquid at
room temperature
29
Explain how you obtain
more building blocks for
DNA through food
30
Anything that you consume that
was once a living thing has DNA
you break down their DNA into
nucleotides & use the units to
make your own DNA
31
Identify the biomolecule.
What is this structure?
32
Carbohydrates, carbon ring
33
What biomolecule is
shown? What determines
the type?
34
Lipids, fatty chains
35
What is this? Label the
parts
36
Nucleotide;
phosphate, sugar,
nitrogen base
37
What is this showing?
38
Amino acid sequence
folding into protein
structure
39
What biomolecule(s) does
not contain nitrogen?
40
Carbohydrates & Lipids
41
What is an enzyme? What
is the primary function?
42
It is a catalyst & speeds up reactions
43
Explain this chart
44
Enzymes speed up
reactions by lowering
activation energy (green
line)
45
Explain what happens if your
body does not have certain
enzymes
46
The chemical reaction may
occur much slowly or not at all
47
What is responsible for the
structure of a protein(enzyme)?
48
Sequence of amino acid chain
49
What conditions should be
present for enzymes to work
at optimal level?
50
Body temperature, neutral pH
level & have plenty of
substrate
51
