A substance responsible for making the stratum lucidum cells of the epidermis of skin of rabbit transparent, is

Options

A. Rhodopsin
B. Eleiden
C. Keratohyaline
D. Luciferin

Explanation

To answer the question about the substance responsible for making the stratum lucidum cells of the epidermis of the skin of a rabbit transparent, we can follow these steps:

### Step 1: Understand the Structure of the Epidermis
The epidermis is the outermost layer of skin and consists of several layers, including the stratum lucidum, which is found only in thick skin areas.

**Hint:** The epidermis has multiple layers, and the stratum lucidum is one of them.

### Step 2: Identify the Composition of Stratum Lucidum
The stratum lucidum is composed of dead keratinocytes that are flattened and packed with a specific substance that contributes to their transparency.

**Hint:** Focus on the characteristics of the cells in the stratum lucidum.

### Step 3: Recognize the Role of Elidin
Elidin is a protein found in the stratum lucidum that helps in making the cells transparent. It is a transformation product of keratohyalin and is responsible for the clear appearance of the cells.

**Hint:** Look for substances that are related to the transparency of skin cells.

### Step 4: Evaluate the Options
The options provided are:
- Rodopsin
- Elidin
- Keratohyline
- Luciferine

Among these, elidin is specifically known for its role in the stratum lucidum.

**Hint:** Compare each option with the function of making cells transparent.

### Step 5: Conclude the Answer
Based on the information gathered, the correct answer is **Elidin**. This substance is responsible for making the stratum lucidum cells of the epidermis of the skin of a rabbit transparent.

**Final Answer:** Elidin
