Which of the following are used in the overall reactions for photosynthesis?
carbon dioxide
water
light
all of the above
Most plants appear green because chlorophyll
does not absorb green light.
reflects violet light.
absorbs green light.
none of the above
If carbon dioxide is removed from a plant’s environment, what would you expect to happen to its production
of high-energy sugars?
More sugars will be produced.
No sugars will be produced.
The same number of sugars will be produced but without carbon dioxide.
Carbon dioxide does not affect the production of high-energy sugars in plants.
Photosynthesis uses sunlight to convert water and carbon dioxide into
oxygen.
high-energy sugars.
ATP and oxygen.
oxygen and high-energy sugars.
What are the reactants in the equation for cellular respiration?

nucleus.
Which of the following is released during cellular respiration?
oxygen
air
energy
lactic acid
Cellular respiration releases energy by breaking down
food molecules.
ATP.
carbon dioxide.
water.
Which of these is a product of cellular respiration?

all of the above
Cellular respiration is called an aerobic process because it requires
light.
exercise.
oxygen.
glucose.
Unlike photosynthesis, cellular respiration occurs in
animal cells only.
plant cells only.
all but plant cells.
all eukaryotic cells.
The products of photosynthesis are the
products of cellular respiration.
reactants of cellular respiration.
products of glycolysis.
reactants of fermentation.
Which is true about photosynthesis and cellular respiration?
Photosynthesis captures light energy and cellular respiration releases energy in the form of ATP
Both photosynthesis and cellular respiration capture sunlight as energy
Photosynthesis uses ATP energy that was made in cellular respiration
Cellular respiration produces sunlight for photosynthesis to use
In terms of photosynthesis and cellular respiration, how do plants and animals depend on each other?
Animals release glucose and oxygen during photosynthesis, which plants take in
Plants release carbon dioxide, which animals need for cellular respiration
Animals release carbon dioxide, which plants take in, and plants release oxygen, which animals take in
Plants absorb sunlight energy, which was released by animals during cellular respiration
Which equation describes what happens in photosynthesis?
C6H12O6+H2O→CO2+energy
6CO2+6H2O+energy→C6H12O6+6O2
C6H12O6+6O2→6CO2+6H2O+energy
CO2+O2+H20+energy→CH2O5
Oxygen is a product of photosynthesis. The primary role of this oxygen in cellular respiration is to:
yield energy in the form of ATP as it is passed down the respiratory chain.
act as an acceptor for electrons and hydrogen, forming water.
combine with carbon, forming CO2.
combine with lactate, forming pyruvate
What is the main purpose of photosynthesis?
To release ATP energy for plants
To create glucose for plants
To keep the plants green
To make water for the plant
Which of these are the products of photosynthesis?
ATP and sunlight
Glucose and oxygen
Water and carbon dioxide
Sunlight and oxygen
Which is true about photosynthesis?
It uses sunlight to turn carbon dioxide and water into glucose and oxygen
It burns glucose as an energy source
It releases ATP energy by taking in carbon dioxide and water
It can be used by animals to turn carbon dioxide into oxygen
What is the main purpose of cellular respiration?
To release ATP energy for organisms
To use sunlight to make glucose
To release oxygen for organisms to breathe
To release carbon dioxide
Which is true about cellular respiration?
It uses sunlight as an energy source
It is used by plants to turn sunlight energy into chemical energy
It is used by organisms to make ATP energy by taking in glucose and oxygen
It is the exact same as photosynthesis

Which statement about photosynthesis is correct?
Plants get the energy they need for photosynthesis from water.
Plants get the energy they need for photosynthesis from soil.
Plants get the energy they need for photosynthesis from sunlight.
Plants do not require energy to perform photosynthesis.

Which of the following do at least one stage of cellular respiration
plants
animals
bacteria
fungi
What happens to the carbon atoms in glucose during cellular respiration?
They are exhaled as CO2
They disappear
They are broken down and dissolve
They stay in the mitochondria forever
Why does the third phosphate in ATP have so much energy stored in the bond?
it is highly unstable
it isn't
it is highly stable
it is moving very fast
What role do NADH and FADH2 (produced during Glycolysis and Kreb's Cycle) play in cellular respiration
they are energy carriers (hydrogen)that use that energy to produce massive amounts of ATP
They are waste products and are pushed out of the cell
They are necessary for long-term energy storage
They don't play any role in cellular respiration
What are the outputs of the kreb's cycle
CO2
H2O
ATP
NADH and FADH2
What happens in the electron transport chain?
NADH and FADH2 drop off hydrogens to form massive amounts of ATP
pyruvic acid is formed from breaking down glucose
CO2 is released and H2O and ATP
glucose is broken down and ATP is formed
