Photosensitive compound int eh human eye which is composed of a protein and an aldehyde of vitamin A is respectively

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a photosensitive compound in the human eye that consists of a protein and an aldehyde derived from vitamin A.

2. **Identifying the Photosensitive Compound**: In the human eye, the primary photosensitive compound responsible for vision is known as "rhodopsin."

3. **Components of Rhodopsin**:
- Rhodopsin is made up of two main components:
- A protein called "opsin."
- An aldehyde derived from vitamin A, which is known as "retinal."

4. **Naming the Components**:
- The protein component is referred to as "opsin."
- The aldehyde component is called "retinal" or "retinal aldehyde."

5. **Conclusion**: Therefore, the photosensitive compound in the human eye composed of a protein and an aldehyde of vitamin A is "rhodopsin," which consists of "opsin" (the protein) and "retinal" (the aldehyde).

**Final Answer**: Rhodopsin (composed of opsin and retinal).
