To assist with the question, let's first outline the chemical equations for both photosynthesis and cellular respiration.
Photosynthesis
The equation for photosynthesis is: \[ 6 , \text{CO}_2 + 6 , \text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}6\text{H}{12}\text{O}_6 + 6 , \text{O}_2 \]
Breakdown of Atoms in Photosynthesis:
-
Reactants (left side):
- Carbon (C): 6 (from 6 CO₂)
- Oxygen (O): 18 (from 6 CO₂ and 6 H₂O; 12 from CO₂ and 6 from H₂O)
- Hydrogen (H): 12 (from 6 H₂O)
-
Products (right side):
- Carbon (C): 6 (from 1 C₆H₁₂O₆)
- Oxygen (O): 6 (from O₂) + 6 (from C₆H₁₂O₆)
- Hydrogen (H): 12 (from C₆H₁₂O₆)
Summary of Atoms for Photosynthesis:
- C (Carbon): 6 | 6
- H (Hydrogen): 12 | 12
- O (Oxygen): 18 | 18
Cellular Respiration
The equation for cellular respiration is: \[ \text{C}6\text{H}{12}\text{O}_6 + 6 , \text{O}_2 \rightarrow 6 , \text{CO}_2 + 6 , \text{H}_2\text{O} \]
Breakdown of Atoms in Cellular Respiration:
-
Reactants (left side):
- Carbon (C): 6 (from C₆H₁₂O₆)
- Oxygen (O): 12 (6 from O₂ and 6 from C₆H₁₂O₆)
- Hydrogen (H): 12 (from C₆H₁₂O₆)
-
Products (right side):
- Carbon (C): 6 (from 6 CO₂)
- Oxygen (O): 18 (from 6 CO₂ and 6 H₂O; 12 from CO₂ and 6 from H₂O)
- Hydrogen (H): 12 (from 6 H₂O)
Summary of Atoms for Cellular Respiration:
- C (Carbon): 6 | 6
- H (Hydrogen): 12 | 12
- O (Oxygen): 12 | 18
Filling the Table:
Now you can input the numbers into the corresponding drop targets for both processes.
For Photosynthesis (12a):
- Drop target 1 (C in reactants): 6
- Drop target 2 (H in reactants): 12
- Drop target 3 (O in reactants): 18
- Drop target 4 (C in products): 6
- Drop target 5 (H in products): 12
- Drop target 6 (O in products): 18
For Cellular Respiration (12b):
- Drop target 1 (C in reactants): 6
- Drop target 2 (H in reactants): 12
- Drop target 3 (O in reactants): 12
- Drop target 4 (C in products): 6
- Drop target 5 (H in products): 12
- Drop target 6 (O in products): 18
