To evaluate the relationship between photosynthesis and cellular respiration and to correctly pair the components in the diagram, let’s first identify the reactants and products for each process.
Photosynthesis (occurs in plants) can be simplified to:
- Reactants: Carbon Dioxide (CO2), Water (H2O), and Sunlight
- Products: Glucose (C6H12O6) and Oxygen (O2)
The equation for photosynthesis is: \[ \text{6 CO2} + \text{6 H2O} + \text{light energy} \rightarrow \text{C6H12O6} + \text{6 O2} \]
Cellular Respiration (occurs in almost all living organisms) can be simplified to:
- Reactants: Glucose (C6H12O6) and Oxygen (O2)
- Products: Carbon Dioxide (CO2), Water (H2O), and ATP
The equation for cellular respiration is: \[ \text{C6H12O6} + \text{6 O2} \rightarrow \text{6 CO2} + \text{6 H2O} + \text{ATP} \]
Given this information, we can analyze the diagram with letters A, B, C, D, and F:
- A (Sunlight) - for photosynthesis.
- B (H2O) - for photosynthesis (as one of the reactants).
- C (C6H12O6) - for cellular respiration (as a reactant) and photosynthesis (as a product).
- D (ATP) - typically considered a product of cellular respiration (but not a direct product of photosynthesis).
- F (CO2 + H2O) - incorrect. While CO2 is produced in cellular respiration, H2O is produced and consumed by photosynthesis and respiration.
Based on this, the correct pairings from your options would be:
- A is sunlight. (Correct)
- B is H2O. (Correct)
- C is C6H12O6. (Also correct, could refer to product of photosynthesis or reactant of cellular respiration)
- D is ATP. (Correct, related to cellular respiration)
- F is CO2 + H2O. (Incorrect, does not correctly represent either process)
Thus, the correct pairs are:
- A is sunlight.
- B is H2O.
- C is C6H12O6.
- D is ATP.
So the correct selections would be A, B, C, and D.
