Insulin and glucagon are involved in the regulation of glucose metabolism. Since it is open access journal, the full text is freely available. However, insulin appears to activate a tyrosine kinase receptor, triggering the phosphorylation of many substrates within the cell. The pancreas is a long, slender organ, most of which is located posterior to the bottom half of the stomach (Figure 17.9.1).Although it is primarily an exocrine gland, secreting a variety of digestive enzymes, the pancreas also has endocrine cells.
