Options

A. Four
B. Five
C. Six
D. Seven

Answer

To determine the total number of hormones from the provided list that bind to intracellular receptors, we will analyze each hormone based on their characteristics and the type of receptors they bind to.

### Step-by-Step Solution:

1. **Identify the Hormones**: The hormones listed are:
- Cortisol
- Testosterone
- T3 (Triiodothyronine)
- Glucagon
- Oxytocin
- FSH (Follicle Stimulating Hormone)
- Progesterone
- ICSH (Interstitial Cell Stimulating Hormone)
- Estrogen
- GH (Growth Hormone)

2. **Classify the Hormones**: We need to classify these hormones into two categories: those that bind to intracellular receptors and those that bind to membrane-bound receptors.
- **Intracellular Receptors**: Typically bind to lipid-soluble hormones (steroid hormones and thyroid hormones).
- **Membrane-bound Receptors**: Typically bind to water-soluble hormones (peptide and protein hormones).

3. **Analyze Each Hormone**:
- **Cortisol**: A steroid hormone that binds to intracellular receptors.
- **Testosterone**: A steroid hormone that binds to intracellular receptors.
- **T3 (Triiodothyronine)**: A thyroid hormone that binds to intracellular receptors.
- **Glucagon**: A peptide hormone that binds to membrane-bound receptors.
- **Oxytocin**: A peptide hormone that binds to membrane-bound receptors.
- **FSH**: A peptide hormone that binds to membrane-bound receptors.
- **Progesterone**: A steroid hormone that binds to intracellular receptors.
- **ICSH**: A peptide hormone that binds to membrane-bound receptors.
- **Estrogen**: A steroid hormone that binds to intracellular receptors.
- **GH (Growth Hormone)**: A peptide hormone that binds to membrane-bound receptors.

4. **Count the Hormones That Bind to Intracellular Receptors**:
- The hormones that bind to intracellular receptors are:
- Cortisol
- Testosterone
- T3
- Progesterone
- Estrogen
- Total: 5 hormones.

5. **Conclusion**: The total number of hormones from the list that bind to intracellular receptors is **5**.

### Final Answer:
The total number of hormones that bind to intracellular receptors is **5**.
