2. site of photosynthesis b. anaerobic
3. process occurs in a mitochondrion c. aerobic
4. c₆h₁₂o₆ d. glucose
5. process does not require oxygen e. atp
6. process requires oxygen f. cell respiration
7. requires sunlight as an energy source h. photosynthesis
8. energy storing molecule of the cell g. heterotrophs
9. organisms that do not make their own food i. autotrophs

directions: answer each of the following questions in a clear and concise manner.

1. write the equation for cell respiration in chemical formula form.
2. write the equation for photosynthesis in chemical formula form.
3. what is the difference in an aerobic process and anaerobic process? which cellular processes are aerobic and anaerobic?
4. our bodies use fermentation when our muscles lack oxygen. what is the type of fermentation used by us? bacteria and yeast also use fermentation in the process of making bread, cheese and yogurt. what type of fermentation do they use?

Explanation:

1. Autotrophs are organisms that produce their own food.
2. Chloroplasts are the site of photosynthesis.
3. Cell respiration occurs in mitochondria.
4. \(C_6H_{12}O_6\) is glucose.
5. Anaerobic processes do not require oxygen.
6. Aerobic processes require oxygen.
7. Photosynthesis requires sunlight.
8. ATP is the energy - storing molecule.
9. Heterotrophs do not make their own food.
10. Cell respiration formula: \(C_6H_{12}O_6+6O_2

ightarrow6CO_2 + 6H_2O+ATP\)

1. Photosynthesis formula: \(6CO_2+6H_2O+sunlight

ightarrow C_6H_{12}O_6+6O_2\)

1. Aerobic needs oxygen (e.g., aerobic respiration), anaerobic doesn't (e.g., anaerobic respiration, fermentation).
2. Humans use lactic acid fermentation; bacteria/yeast use alcoholic fermentation.

Answer:

1. I. Autotrophs
2. A. Chloroplasts
3. F. cell respiration
4. D. Glucose
5. B. Anaerobic
6. C. Aerobic
7. H. Photosynthesis
8. E. ATP
9. G. Heterotrophs
10. \(C_6H_{12}O_6+6O_2

ightarrow6CO_2 + 6H_2O+ATP\)

1. \(6CO_2+6H_2O+sunlight

ightarrow C_6H_{12}O_6+6O_2\)

1. Aerobic needs oxygen (e.g., aerobic respiration), anaerobic doesn't (e.g., anaerobic respiration, fermentation).
2. Lactic acid fermentation; alcoholic fermentation.
