Define Glucose, Ghrelin, and Cholecystokinin, and Compare the Mechanisms by Which

Question

Examlex · Accepted Answer

The Answer is The answer should include the following information: Glucose, also called blood sugar, is a simple sugar that provides energy. The levels of glucose in the blood fluctuate very little over the course of a day. However, a slight decrease in blood glucose levels does tend to occur about 30 minutes before mealtime. Studies suggest that these changes reliably predict the initiation of eating. Glucose returns to baseline levels after a meal is begun but before food is digested and absorbed. In fact, even if you do not eat, your glucose levels will return to baseline. Ghrelin, also called the hunger hormone, strongly stimulates appetite and prompts eating. Ghrelin levels in the blood rise sharply before a meal and fall sharply after a meal. Cholecystokinin, a hormone secreted by the small intestines, increases the sensitivity of stretch receptors in your stomach. These receptors send messages to the brain signaling fullness.
