Question

Choose roles of insulin in energy balance.

Multiple select question.

promotes glucose and fatty acid uptake


promotes triglyceride synthesis in the liver


inhibits lipolysis in fat cells


inhibits adipogenesis (production of new fat cells)

Answer 1

Insulin plays several critical roles in energy balance. The correct selections from your options are:

1. **Promotes glucose and fatty acid uptake** - Insulin facilitates the uptake of glucose by muscle and fat cells, as well as promoting the uptake of fatty acids.

2. **Promotes triglyceride synthesis in the liver** - Insulin promotes the conversion of excess glucose into triglycerides in the liver for storage.

3. **Inhibits lipolysis in fat cells** - Insulin inhibits the breakdown of fat (lipolysis) in adipose tissue, helping to maintain fat storage.

The statement **“inhibits adipogenesis (production of new fat cells)”** is incorrect; insulin actually promotes adipogenesis, so it should not be selected.

Therefore, the correct roles of insulin in energy balance from your options are:

- Promotes glucose and fatty acid uptake
- Promotes triglyceride synthesis in the liver
- Inhibits lipolysis in fat cells
