Final answer:
Insulin has several main actions on the liver, including promoting glucose uptake, glycogen storage, and protein synthesis.
Step-by-step explanation:
Insulin plays a vital role in controlling glucose metabolism in the liver. It has several main actions on the liver:
- Insulin promotes the uptake of glucose by liver cells, allowing them to use it for energy production.
- Insulin stimulates the liver to convert excess glucose into glycogen, which is stored for later use.
- Insulin inhibits the breakdown of glycogen in the liver, preventing excessive release of glucose into the bloodstream.
- Insulin promotes protein synthesis in the liver, leading to the production of new proteins.
