Word Bank:


Processes: ATP Synthase, Calvin Cycle, Electron Transport Chain, Photosystem I, Photosystem II


Locations: Stroma, Thylakoid Membrane


Reactants: ADP, ATP, Carbon Dioxide, NADP+, NADPH, Sunlight, Water


Products: ADP, ATP, NADPH, NADP+, Oxygen, Sugars

Answer 1

To organize the terms into the correct columns that describe the reactions of photosynthesis, we can separate them into Processes, Locations, Reactants, and Products as follows:

### Processes:
- ATP Synthase
- Calvin Cycle
- Electron Transport Chain
- Photosystem I
- Photosystem II

### Locations:
- Stroma
- Thylakoid Membrane

### Reactants:
- ADP
- Carbon Dioxide
- NADP+
- Sunlight
- Water

### Products:
- ATP
- NADPH
- NADP+
- Oxygen
- Sugars

### Clarification of the terms:

1. **Processes**:
- **Photosystem II** and **Photosystem I** are involved in the light-dependent reactions.
- **Electron Transport Chain** is the sequence of proteins that transfer electrons from photosystem II to photosystem I.
- **ATP Synthase** is the enzyme that synthesizes ATP from ADP and inorganic phosphate during the light-dependent reactions.
- **Calvin Cycle** occurs in the stroma and uses ATP and NADPH produced in the light reactions to convert carbon dioxide into sugars.

2. **Locations**:
- **Thylakoid Membrane** is where the light-dependent reactions occur.
- **Stroma** is where the Calvin Cycle takes place.

3. **Reactants**:
- **Sunlight** is needed for the light-dependent reactions.
- **Water** is split to release oxygen and provide electrons during the light-dependent reactions.
- **Carbon Dioxide** is utilized in the Calvin Cycle.
- **ADP** and **NADP+** are reduced to create **ATP** and **NADPH** in the light-dependent reactions.

4. **Products**:
- **Oxygen** is released as a byproduct of splitting water.
- **ATP** and **NADPH** are generated during the light-dependent reactions and used in the Calvin Cycle.
- **Sugars** are produced in the Calvin Cycle from carbon dioxide.
