Tweet Text Figure 45.End of Chapter Pathway Negative feedback - Stimulus Endocrine cell Hormone Blood vessel Target cells Response Glycogen breakdown, glucose release into blood Liver Pancreas secretes glucagon ( ). Low blood glucose Example Figure 45.13 Body cells take up more glucose. Insulin Beta cells of pancreas release insulin into the blood. Liver takes up glucose and stores it as glycogen. Blood glucose level declines. Blood glucose level rises. Homeostasis: Blood glucose level (70–110 mg/m100mL) STIMULUS: Blood glucose level rises (for instance, after eating a carbohydrate-rich meal). Liver breaks down glycogen and releases glucose into the blood. Alpha cells of pancreas release glucagon into the blood. Glucagon STIMULUS: Blood glucose level falls (for instance, after skipping a meal). Which of the following would be released in the body in response to high blood glucose levels? A. glucagon to increase glycogen breakdown to glucose B. insulin to stimulate glucose uptake by cells C. glucagon to stimulate glucose uptake by cells D. insulin to stimulate glycogen breakdown to glucose E. neither insulin or glucagon
