Photosynthetic reaction centre from photosynthetic bacterium was crystallised by

Options

A. Gulirrez
B. Burnell and Hatch
C. Fluggs and Heldt
D. Hunber, Mutchel and Deisenhofer.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the scientists who crystallized the photosynthetic reaction center from photosynthetic bacteria.

2. **Analyzing the Options**: We have four options to consider:
- Option 1: Guterres
- Option 2: Bernal and Hatch
- Option 3: Flux and Health
- Option 4: Hubbard, Michel, and Dessenhofer

3. **Evaluating Each Option**:
- **Option 1 (Guterres)**: Known for improving crop yields by enhancing photosynthetic rates, but not related to crystallization.
- **Option 2 (Bernal and Hatch)**: They focused on the regulation of C4 photosynthesis, not on crystallization.
- **Option 3 (Flux and Health)**: Their research pertains to phytohormones, which is unrelated to the crystallization of photosynthetic reaction centers.
- **Option 4 (Hubbard, Michel, and Dessenhofer)**: These scientists are recognized for their work in crystallizing the photosynthetic reaction center and were awarded the Nobel Prize for this achievement.

4. **Conclusion**: Based on the evaluation, the correct answer is **Option 4: Hubbard, Michel, and Dessenhofer**.

**Final Answer**: The photosynthetic reaction center from photosynthetic bacteria was crystallized by Hubbard, Michel, and Dessenhofer.
