Which of the following statement is false?

Options

A. Insulin stimulates cellular glucose uptake and utilisation and glycogenesis
B. Insulin deficiency result in a disease called diabetes mellitus
C. Glucagon inhibits glycogenolysis and gluconeogenesis
D. Thymosin increases the production of antibodies to provide humoral immunity

Answer

To determine which statement is false among the provided options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement 1: Insulin stimulates cellular glucose uptake and utilization and glycogenesis.**
- Insulin is a peptide hormone secreted by the beta cells of the pancreas. It plays a crucial role in lowering blood glucose levels by promoting the uptake of glucose by cells and facilitating glycogenesis, which is the conversion of excess glucose into glycogen for storage.
- **Conclusion:** This statement is true.

2. **Statement 2: Insulin deficiency results in a disease called diabetes mellitus.**
- Insulin deficiency leads to diabetes mellitus, a condition characterized by high blood sugar levels due to the body's inability to produce or effectively use insulin.
- **Conclusion:** This statement is true.

3. **Statement 3: Glucagon inhibits glycogenolysis and gluconeogenesis.**
- Glucagon is a hormone that works antagonistically to insulin. It increases blood glucose levels by promoting glycogenolysis (the breakdown of glycogen into glucose) and gluconeogenesis (the formation of glucose from non-carbohydrate sources).
- The statement claims that glucagon inhibits these processes, which is incorrect.
- **Conclusion:** This statement is false.

4. **Statement 4: Thymosin increases the production of antibodies to provide humoral immunity.**
- Thymosin is a hormone produced by the thymus gland that plays a role in the development of T cells. While thymosin itself does not directly increase antibody production, it is involved in the immune response, which includes the activation of B cells that produce antibodies.
- **Conclusion:** This statement is true.

### Final Answer:
The false statement is **Statement 3: Glucagon inhibits glycogenolysis and gluconeogenesis.**
