Comparing and Contrasting Photosynthesis and Cellular Respiration
1. The diagram below represents a cell structure involved in
converting energy stored in organic molecules into a form used
by animal cells.
4. The diagram below represents a plant cell.
The arrows represent the movement of which substances?
1)
2)
3)
4)
Which process takes place in structure A?
carbon dioxide and sugar
oxygen and ATP
ATP and carbon dioxide
oxygen and sugar
1) cellular respiration
3) digestion of fats
2. The diagram below represents a cell of a green plant.
2) photosynthesis
4) protein synthesis
5. The cells of some organisms contain both chloroplasts and
mitochondria. Which statement describes what would happen in
these cells if they were moved from a light environment to a dark
one?
1) The amount of oxygen present would decrease and the
amount of carbon dioxide would increase
2) The amount of glucose present would increase and ATP
would no longer be available
3) The amount of carbon dioxide present would decrease and
ATP would continue to be synthesized
4) The amount of oxygen present would increase and the
amount of glucose available would decrease
6. What does the process of photosynthesis produce?
Solar energy is used to produce energy-rich compounds in
structure
1) A
2) B
3) C
4) D
3. Which phrase best describes cellular respiration, a process that
occurs continuously in the cells of organisms?
1) removal of oxygen from the cells of an organism
2) conversion of light energy into the chemical bond energy of
organic molecules
3) transport of materials within cells and throughout the bodies
of multicellular organisms
4) changing of stored chemical energy in food molecules to a
form usable by organisms
1) starch, which is metabolized into less complex molecules by
synthesis
2) protein, which is metabolized into less complex molecules
by synthesis
3) glycerol, which is metabolized into more complex
carbohydrates by synthesis
4) glucose, which is metabolized into more complex
carbohydrates by synthesis
7. Which process uses energy to combine inorganic molecules to
synthesize organic molecules?
1) respiration
3) photosynthesis
2) digestion
4) decomposition
