Insulin differs from Growth hormone in :

Options

A. Increases activity of m -RNA and Ribosomes.
B. Increase the permeability of cell membrane
C. Affects metabolism of fats by inducing lipogenesis
D. Increasing protein synthesis

Answer

To determine how insulin differs from growth hormone, we will analyze the options provided and evaluate their correctness based on the functions of these hormones.

### Step-by-Step Solution:

1. **Understanding Insulin and Growth Hormone**:
- Insulin is a peptide hormone produced by the pancreas that primarily regulates glucose levels in the blood and promotes lipogenesis (fat storage).
- Growth hormone (GH), produced by the pituitary gland, stimulates growth, cell reproduction, and regeneration in humans and other animals.

2. **Evaluating the Options**:
- **Option 1**: "Increases the activity of the messenger RNA and the ribosomes."
- **Analysis**: This statement is incorrect for insulin. While growth hormone does influence protein synthesis and can increase mRNA activity, insulin primarily regulates glucose metabolism and fat storage rather than directly affecting mRNA and ribosome activity.

- **Option 2**: "Increases the permeability of the cell membrane."
- **Analysis**: This option is also incorrect. Insulin does facilitate glucose uptake by increasing the number of glucose transporters on the cell membrane, but it does not generally increase membrane permeability in the same way that growth hormone affects cell growth and metabolism.

- **Option 3**: "Affects metabolism of the fats by inducing lipogenesis."
- **Analysis**: This statement is correct. Insulin promotes lipogenesis, which is the process of converting glucose into fatty acids for storage. It activates key enzymes such as pyruvate dehydrogenase and acetyl-CoA carboxylase, which are involved in fat metabolism.

- **Option 4**: "Increasing protein synthesis."
- **Analysis**: This option is incorrect regarding insulin. While insulin does play a role in protein metabolism, it is not primarily known for increasing protein synthesis. Growth hormone is more directly involved in stimulating protein synthesis and increasing the basal metabolic rate.

3. **Conclusion**:
- Based on the evaluations, the correct answer is **Option 3**, which states that insulin affects the metabolism of fats by inducing lipogenesis. The other options do not accurately describe the primary functions of insulin compared to growth hormone.

### Final Answer:
Insulin differs from growth hormone in that it affects the metabolism of fats by inducing lipogenesis (Option 3).
