Rhodopsin is a constituent of

Options

A. Cornea
B. choroid
C. rods
D. cones

Answer

**Step-by-Step Solution:**

1. **Understanding Rhodopsin**: Rhodopsin is a visual pigment that plays a crucial role in the phototransduction process, which is how light is converted into electrical signals in the retina.

2. **Identifying the Location**: Rhodopsin is specifically found in the photoreceptor cells of the retina. The retina contains two types of photoreceptor cells: rods and cones.

3. **Differentiating Rods and Cones**:
- Rods are responsible for vision in low light conditions (twilight vision) and contain the pigment Rhodopsin.
- Cones are responsible for color vision and function best in bright light, containing different types of photopigments.

4. **Conclusion**: Since Rhodopsin is specifically associated with rods, the correct answer to the question "Rhodopsin is a constituent of" is "rods".

5. **Final Answer**: Rhodopsin is a constituent of rods.
