Answers
1
Organisms, such as plants, that make their own food are called
pigments
thylakoids
producers
consumers
2
Plants gather the sun's energy with light-absorbing molecules called
chloroplasts
thylakoids
pigments
glucose
3
The products of photosynthesis are the
reactants of cellular respiration
reactants of fermentation
products of cellular respiration
products of glycolysis
4
The two main types of fermentation are called
aerobic and anaerobic
lactic acid and anaerobic
alcoholic and aerobic
alcoholic and lactic acid
5
In eukaryotes, electron transport occurs in the
cell membrane
mitochondria
cytoplasm
chloroplasts
6
Most plants appear green because chlorophyll
absorbs green light
does not absorb green light
reflects violet light
7
In the presence of oxygen, glycolysis is followed by
lactic acid fermentation
photosynthesis
alcoholic fermentation
the Krebs cycle
8
How are cellular respiration and photosynthesis almost opposite processes?
Photosynthesis uses oxygen, cellular respiration produces it
Photosynthesis uses CO2, cellular respiration produces it
9
If carbon dioxide is removed from a plant's environment, what would happen to sugar production?
Less sugars produced
Same amount of sugars produced
No affect
More sugars produced
10
If you continue to increase the intensity of light that a plant receives, what happens?
rate of photosynthesis decreases
rate of photosynthesis does not change
rate of photosynthesis increases, then levels off
rate of photosynthesis increases
11

14
Cellular respiration is called an aerobic process because it requires
light

oxygen
exercise
15
The Krebs cycle starts with
acetyl CoA and yields lactic acid or alcohol
glucose and yields 32 ATPs

16
Energy is released from ATP when
ATP is exposed to sunlight
a phosphate group is removed
a phosphate group is added
adenine bonds to ribose
17
The stroma is the thick fluid within the inner membrane of a chloroplast that surrounds
chloroplasts
plant cells
thylakoids
18
Breathing heavily after running a race is your body's way of
repaying an oxygen debt
making more citric acid
restarting glycolysis
recharging the electron transport chain
