Question
cell energy phrases
directions: choose whether each phrase below best represents photosynthesis or cellular respiration. write the phrase in the appropriate column on your answer sheet.
| occurs in plants and animals | uses food |
| occurs in mitochondria | adds carbon dioxide to the atmosphere |
| removes carbon dioxide from the atmosphere | adds oxygen to the atmosphere |
| reactants are glucose and oxygen | uses oxygen from the atmosphere |
| makes food | occurs in chloroplasts |
| uses carbon dioxide | produces carbon dioxide |
| $\text{c}_6\text{h}_{12}\text{o}_6 + 6\text{o}_2 \
ightarrow 6\text{co}_2 + 6\text{h}_2\text{o}$ | anabolic process (it builds complex molecules from simpler ones) |
| uses a carbon atom in glucose to make carbon dioxide | uses carbon atoms from carbon dioxide molecules to make glucose |
| products are glucose and oxygen | energy source: sunlight |
| products are carbon dioxide and water | reactants are carbon dioxide and water |
| energy is released | energy is absorbed and stored |
| occurs in plants | energy source: glucose |
| catabolic process (it breaks down complex molecules into simpler ones) | $6\text{co}_2 + 6\text{h}_2\text{o} \
ightarrow \text{c}_6\text{h}_{12}\text{o}_6 + 6\text{o}_2$ |
To solve this, we analyze each phrase based on the definitions of photosynthesis (PS) and cellular respiration (CR):
Photosynthesis (PS) Key Points:
- Occurs in chloroplasts (plant cells).
- Removes \( \text{CO}_2 \) from the atmosphere (uses \( \text{CO}_2 \)).
- Adds \( \text{O}_2 \) to the atmosphere.
- Makes food (glucose) from \( \text{CO}_2 + \text{H}_2\text{O} \).
- Reactants: \( \text{CO}_2 + \text{H}_2\text{O} \); Products: \( \text{C}_6\text{H}_{12}\text{O}_6 + \text{O}_2 \).
- Energy source: sunlight (anabolic: builds complex molecules).
- Equation: \( 6\text{CO}_2 + 6\text{H}_2\text{O}
ightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \).
Cellular Respiration (CR) Key Points:
- Occurs in mitochondria (plants and animals).
- Uses food (glucose) and \( \text{O}_2 \) from the atmosphere.
- Adds \( \text{CO}_2 \) to the atmosphere (produces \( \text{CO}_2 \)).
- Breaks down glucose (catabolic: releases energy).
- Reactants: \( \text{C}_6\text{H}_{12}\text{O}_6 + \text{O}_2 \); Products: \( \text{CO}_2 + \text{H}_2\text{O} \).
- Energy source: glucose (releases energy).
- Equation: \( \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2
ightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} \).
Categorization:
| Phrase | Photosynthesis (PS) or Cellular Respiration (CR)? |
|---|---|
| Uses Food | CR |
| Occurs in Mitochondria | CR |
| Adds Carbon Dioxide to the Atmosphere | CR |
| Removes Carbon Dioxide from the Atmosphere | PS |
| Adds Oxygen to the Atmosphere | PS |
| Reactants are Glucose and Oxygen | CR |
| Uses Oxygen from the Atmosphere | CR |
| Makes Food | PS |
| Occurs in Chloroplasts | PS |
| Uses Carbon Dioxide | PS |
| Produces Carbon Dioxide | CR |
| \( \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2
ightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} \) | CR |
| Anabolic Process (builds complex molecules) | PS |
| Uses a Carbon Atom in Glucose to Make Carbon Dioxide | CR |
| Uses Carbon Atoms from \( \text{CO}_2 \) to Make Glucose | PS |
| Products are Glucose and Oxygen | PS |
| Energy Source: Sunlight | PS |
| Products are Carbon Dioxide and Water | CR |
| Reactants are Carbon Dioxide and Water | PS |
| Energy is Released | CR |
| Energy is Absorbed and Stored | PS |
| Occurs in Plants | PS (also CR occurs in plants, but PS is unique to plants) |
| Energy Source: Glucose | CR |
| Catabolic Process (breaks down complex molecules) | CR |
| \( 6\text{CO}_2 + 6\text{H}_2\text{O}
ightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \) | PS |
Example Application (e.g., "Occurs in Chloroplasts"):
- Chloroplasts are the site of photosynthesis (CR occurs in mitochondria). Thus, "Occurs in Chloroplasts" → PS.
Final Answer (for a specific phrase, e.g., "Makes Food"):
"Makes Food" represents Photosynthesis (PS), as photosynthesis produces glucose (food) from \( \text{CO}_2 \) and \( \text{H}_2\text{O} \).
(Adjust the answer based on the specific phrase you want to analyze.)
