Steroid hormones binds with ______ receptors and promotes ______ synthesis where protein hormones binds with ______ receptors :

Options

A. Cytoplasmic, carbohydrate, intranuclear
B. Intranuclear, Protein, Cytoplasmic
C. Intranuclear, protein, cell membrane
D. Cell membrane, Carbohydrate, intranuclear

Answer

To answer the question, we need to identify where steroid hormones and protein hormones bind and what they promote.

### Step-by-Step Solution:

1. **Identify the type of receptors for steroid hormones**:
- Steroid hormones are lipophilic (fat-soluble) molecules. They can easily pass through the cell membrane and bind to receptors located inside the cell.
- These receptors are typically found in the cytoplasm or nucleus of the target cells, known as **intracellular receptors**.

2. **Determine what steroid hormones promote**:
- Once steroid hormones bind to their intracellular receptors, they often promote the synthesis of proteins by influencing gene expression in the nucleus. Therefore, they promote **protein synthesis**.

3. **Identify the type of receptors for protein hormones**:
- Protein hormones are generally hydrophilic (water-soluble) and cannot easily cross the cell membrane. Instead, they bind to receptors located on the surface of the cell membrane.
- These receptors are known as **cell membrane receptors**.

4. **Summarize the findings**:
- Steroid hormones bind with **intracellular receptors** and promote **protein synthesis**.
- Protein hormones bind with **cell membrane receptors**.

### Final Answer:
Steroid hormones bind with **intracellular receptors** and promote **protein synthesis**, while protein hormones bind with **cell membrane receptors**.
