Insulin plays several critical roles in energy balance. The correct selections from your options are:
-
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.
-
Promotes triglyceride synthesis in the liver - Insulin promotes the conversion of excess glucose into triglycerides in the liver for storage.
-
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
