Vocabulary Matching:

1. Organisms that make their own food → J. Autotrophs
*(Autotrophs, like plants, produce their own food via photosynthesis.)*

2. Site of photosynthesis → A. Chloroplasts
*(Photosynthesis occurs in chloroplasts in plant cells.)*

3. Process occurs in cytoplasm → G. Glycolysis
*(Glycolysis, the first step of cellular respiration, happens in the cytoplasm.)*

4. C₆H₁₂O₆ → D. Glucose
*(This is the chemical formula for glucose, a key sugar molecule.)*

5. Process does not require oxygen → B. Anaerobic
*(Anaerobic processes occur without oxygen — e.g., fermentation or glycolysis alone.)*

6. Process requires oxygen → C. Aerobic
*(Aerobic respiration requires oxygen — includes Kreb’s cycle and electron transport chain.)*

7. Adenosine triphosphate → E. ATP
*(ATP is the full name of adenosine triphosphate, the energy currency of the cell.)*

8. Energy storing molecule → E. ATP
*(ATP stores energy in its phosphate bonds for later use.)*

9. The anaerobic process of splitting glucose and forming two molecules of pyruvic acid → G. Glycolysis

11. Fill out the table:

| | Cellular Respiration | Photosynthesis |
|--------------------------|--------------------------------------------------|-----------------------------------------------|
| Reactants | Glucose (C₆H₁₂O₆) + Oxygen (O₂) | Carbon Dioxide (CO₂) + Water (H₂O) + Light |
| Products | Carbon Dioxide (CO₂) + Water (H₂O) + ATP | Glucose (C₆H₁₂O₆) + Oxygen (O₂) |
| What organelle? | Mitochondria (mainly; glycolysis in cytoplasm) | Chloroplasts |

Explanation:

- Cellular Respiration Equation:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
*Glucose and oxygen are broken down to release energy (ATP), producing CO₂ and water.*

- Photosynthesis Equation:
6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂
*Plants use sunlight, carbon dioxide, and water to build glucose and release oxygen.*

- Organelles:
- Cellular respiration primarily occurs in mitochondria (except glycolysis, which is in the cytoplasm).
- Photosynthesis occurs in chloroplasts, which contain chlorophyll to capture light.
