A 22-year-old medical student is studying for his boards and experiences chronic stress. Over several weeks, he maintains high levels of cortisol.
How does cortisol primarily affect glucose metabolism to help the body cope with stress?
- It suppresses the release of glucagon from the pancreas.
- It stimulates gluconeogenesis in the liver and promotes protein catabolism.
- It increases the sensitivity of muscle cells to insulin, promoting glucose storage.
- It stimulates glycolysis in the liver to increase ATP production.
