Name: Nghi Ho Period 1Feedback Loops: Glucose and GlucagonThe control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. Whenblood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulininto the blood effectively lowering blood sugar levels. Once blood sugar levels reach homeostasis, thepancreas stops releasing insulin. Examine the graphic below to understand how this feedback loop works.1. The image shows two different types of stimuli (1 and 2), but doesn't explain what the stimuli is that causesblood sugar to rise or lower. Based on clues in the graphic, what are the two stimuli?
2. What happens when your blood sugar rises?
3. What is the effect of glucagon? What cells release glucagon?
