The product of light reaction in green algae is

Options

A. ATP, NADPH + `H^(+)`
B. `NAD+ `
C. NADP
D. ATP and NADH

Answer

To solve the question regarding the products of the light reaction in green algae, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Photosynthesis**: Photosynthesis occurs in two main stages: the light reactions and the dark reactions (Calvin cycle). The light reactions require light to produce energy-rich compounds.

2. **Identify the Location of Light Reactions**: The light reactions take place in the thylakoid membranes of chloroplasts in green algae.

3. **Know the Inputs of Light Reactions**: The primary inputs for the light reactions are water (H₂O) and light energy.

4. **Understand the Process of Photolysis**: During the light reactions, water molecules undergo photolysis, which means they are split into oxygen (O₂), protons (H⁺), and electrons (e⁻).

5. **Identify the Products of Light Reactions**: The main products of the light reactions are:
- ATP (adenosine triphosphate)
- NADPH (nicotinamide adenine dinucleotide phosphate)
- H⁺ ions (protons)

6. **Conclusion**: Therefore, the correct answer to the question about the products of the light reaction in green algae is ATP, NADPH, and H⁺ ions.

### Final Answer:
The product of the light reaction in green algae is ATP, NADPH, and H⁺ ions.
