What did sutherland discover about glycogen metabolism in liver cells?
anyanavicka [17]

Answer:

The hormone epinephrine binds to a specific receptor on the plasma membrane of the liver cell.

Explanation:

Glycogen is the body's rapid energy supply, which is how glucose, the main energy source of cells - derived from carbohydrate consumption - is stored. Glycogen is found mainly in muscle (muscle glycogen) and liver (liver glycogen), where liver cells are found.  Glycogen is important for the production of ATP in muscle cells and most other cell types.

Based on this information, researcher Earl Wilbur Sutherland Jr. decided to conduct a study to find out what were the effects of epinephrine during glycogen metabolism on liver cells. In this study, the researcher concluded that during the process of glycogen decomposition into glucose, the epinephrine hormone binds to a specific receptor on the liver cell plasma membrane.
