answer
homeostasis, food, water and shelter
and fresh air
question

answer
02
question

formula of glucose?
answer
c6 h 12 o 6
question

answer
co2
question
What is the chemical formula of water
answer
h2o
question
Predict: Of the molecules shown on the MOLECULES pane, which do you think are inputs
(ingredients) in photosynthesis? W hich do you think are outputs?
answer
Inputs:
h20 and carbon dioxide
question
Which molecules are inputs in photosynthesis?
answer
H2o and carbon dioxide
question
Observe: Click Add light and look at the Output. What are the outputs of photosynthesis?
answer
oxygen and c6 h12 o6
question
Summarize: Although photosynthesis is a complex process involving many reactions, it can
be summarized by a simplified formula that shows inputs on the left and outputs on the right.
Based on your observations, write a simplified formula for photosynthesis:
answer
h2o + co2 -> 02 + c6 h12 o6
question
Turn on Show input/output formula to check. Were you correct?
answer
Yep!
question
Is the formula balanced as written? Why or why not?
answer
No because there is 6 oxygen on one side and 2 on the other
question
Now balance the input/output formula by adding coefficients to each molecule. Write
the balanced formula below, and then check your work by clicking Balance.
answer
6H20 + 6c02 -> 602 + c6h1206
question
Predict: Of the molecules shown on the MOLECULES pane, which do you think are inputs
(ingredients) in cellular respiration? Which do you think are outputs?
answer
Inputs - c6 h12 o6 and o2
Outputs - c02 and h20
question
Explore: Drag each molecule from the MOLECULES pane to the RESPIRATION pane.
Which molecules are inputs in cellular respiration?
answer
c6 h12 o6 and o2
question
Observe: Click Next. What happens in the cytoplasm?
answer
Energy is created and the c6 h12 o6 goes away
question
Observe: Click Next. What happens now?
answer
The pyruvate molecules
question
Observe: Click Next. What happens in the mitochondrion?
answer
More energy was created and you get the CO2 and h20
question
Analyze: Cellular respiration involves two phases. The anaerobic phase does not involve
oxygen, while the aerobic phase does. Where does each phase take place?
answer
Anaerobic: inside of the cytoplasm
Aerobic: inside of the mitochondria
question
Summarize: Based on what you have seen, write a simplified formula for cellular respiration.
answer
c6h1206 + 02 -> C02 + h20
question
Turn on Show input/output formula to check. Were you correct?
answer
yessirr
question
Is the formula balanced as written? Why or why not? _
answer
no the quantities are not the same
question
Now balance the input/output formula by adding coefficients to each molecule. Write
the balanced formula below, and then check your work by clicking Balance.
answer
c6h1206 + 602 -> 6C02 + h20
question
Compare: The aerobic phase of cellular respiration in the mitochondrion produces a net of
about 28 to 30 ATP molecules. How does this compare to the energy released in glycolysis?
answer
no there are more c, h and o atoms on the left
question
How is breathing related to cellular respiration? (Hint: Think about both the inputs and the
outputs of cellular respiration.)
answer
when you breathe you take in something similar to when your cells reperate
question
Form a hypothesis: How do you think photosynthesis is related to cellular respiration?
answer
I think they are related because they have the opposite inputs and outputs
question
Which molecules would you expect to find at the top of the diagram? Explain.
answer
c6h1202 and 02, they are both products of photosynthesis and reactants of respiration
question
Which molecules would you expect to find at the bottom of the diagram? Explain.
answer
c02 and h20 are both products of respiration and reactants of photo synthesis
question
Which substances are inputs in photosynthesis?
answer
c02 and h20
question
Which substances are outputs of photosynthesis?
answer
c6h1206 and 02
question
Which substances are inputs in respiration?
answer
c6h1206 and 02
question
Which substances are outputs of respiration?
answer
c02 and h20
question
Compare: How are the inputs and outputs of photosynthesis and respiration related to one
another?
answer
The reactants are the same as the products of photosynthesis compared to respiration and visa - versa
question
During photosynthesis, what role is played by the radiant energy of the Sun? Explain
your answer
answer
it gives plants the energy they need to produce glucose
question
In photosynthesis, what form of energy is sunlight converted to, and how is this
energy stored?
answer
its converted to chemical energy to produce ATP
question
Does cellular respiration result in a net input of energy or a net output of energy?
Explain.
answer
cellular respiration results in a net output of energy
question
How is the energy produced by respiration stored?
answer
cells can store energy in the atp
question
Summarize: How are respiration and photosynthesis related to each other?
answer
photosynthesis produces the glucose that is used in respiration
question
Think and discuss: In what ways are plants and animals dependent on each other?
answer
animals need oxygen, therefore the plants must make the CO2 and plants need fertilizer so when animals pass away there corpses can then be used as fertilizer
