Photosensitive compound in human eye is made up of

Options

A. Transducin and Retinene
B. Guanosine and Retinol
C. Opsin and Retinal
D. Opsin and Retinol

Answer

**Step-by-Step Solution:**

1. **Understanding Photosensitive Cells:**
- The human eye contains two types of photosensitive cells: rods and cones. These cells are responsible for detecting light and enabling vision.

2. **Identifying Photosensitive Compounds:**
- Within these cells, there are specific pigments that are sensitive to light. One of the most important pigments is rhodopsin, which is found in rod cells.

3. **Components of Rhodopsin:**
- Rhodopsin is a complex molecule made up of a protein called opsin and a light-sensitive molecule called retinal (also referred to as retinol in some contexts).

4. **Function of Rhodopsin:**
- The combination of opsin and retinal allows the cells to respond to light. When light hits rhodopsin, it undergoes a conformational change, which ultimately leads to the generation of nerve impulses that are sent to the brain for visual processing.

5. **Conclusion:**
- Therefore, the photosensitive compound in the human eye is made up of opsin and retinal.

**Final Answer:**
The photosensitive compound in the human eye is made up of opsin and retinal.
