So basically, our glucagon is released when we have low concentrations of glucose, but insulin is released when we have high concentrations of glucose. For example, right after we ate. So let's suppose we just ate a meal and our body broke down our glucose. And now we have plenty of glucose circulating inside our blood. So what happens is glucagon is inhibited, but insulin is stimulated. And these baby cells basically release insulin, which is a peptide hormone, it's a water soluble hormone.
