Unit #5 Pre-Assessment - Cellular Energy
Question #1
During photosynthesis, plant cells take in water (H2O) and carbon dioxide (CO2) and release
oxygen (O2). How is this different from what takes place during aerobic respiration?
A.
During aerobic respiration, cells use ATP to convert insulin into glucose and CO2.
B.
During aerobic respiration, cells take in O2 and release CO2, H2O, and ATP.
C.
During aerobic respiration, O2 is inhaled and CO2 and H2O are exhaled.
D.
During aerobic respiration, the mitochondria form CO2 during the process of fermentation.
Question #2
In what part of a plant does photosynthesis occur?
A.
1
B.
4
C.
2
D.
3
Question #3
What type of energy transformation takes place during photosynthesis?
A.
Potential energy is converted into kinetic energy.
B.
Light energy is converted into chemical energy.
C.
Chemical energy is converted into chemical energy.
D.
Chemical energy is converted into light energy.
Question #4
During photosynthesis, plants capture light energy from the Sun to break weak bonds in
reactants, such as carbon dioxide and water, and form carbon-containing molecules, such as
glucose. The carbon-containing molecules can then be used
A.
to synthesize essential amino acids.
B.
to produce inorganic compounds, such as sulfuric acid.
C.
to assemble larger molecules, such as DNA, proteins, and fats.
D.
all of these
Question #5
Photosynthesis occurs in two sets of reactions within the chloroplast: light-dependent reactions
and light-independent (dark) reactions.
Light-dependent reactions occur inside grana, which are stacks of membrane-bound disks found
within chloroplasts. What is the main purpose of the light-dependent reactions?
A.
to produce water using oxygen from the air
B.
to produce sugar molecules using ATP, NADPH, and CO2
C.
to convert light energy directly into glucose molecules
D.
to convert light energy into the chemical energy of ATP and NADPH

4 CO2 + 10 H2O + 4 NO2
C.
C6H12O6 + 6 O2
6 CO2 + 6 H2O + ATP
D.
CH4 + O2
CO2 + H2O
Question #8
The graph below shows the effect of carbon dioxide levels on the rate of photosynthesis.
If the amount of carbon dioxide available to the plant approaches zero, what will happen to the
plant's rate of photosynthesis?
A.
It will not change.
B.
It will increase.
C.
It will decrease.
D.
It will increase, then decrease.

A.
Increasing the temperature always increases the reaction rate.
B.
Temperature can affect a biochemical reaction.
C.
Temperature never affects a biochemical reaction.
D.
Decreasing the temperature always decreases the reaction rate.
