Healthy and diabetic individuals participated in a study in which their blood sugar, insulin, and glucagon levels were regularly measured over a 12 h period. Each of the participants ate a meal at the beginning of the experiment, exercised midway through the experiment, and received an insulin injection toward the end of the experiment. Analyze the graphs to determine which data profile fits that of a healthy individual, an individual with Type 1 diabetes mellitus, or an individual with Type 2 diabetes mellitus.
