Multiple Choice
If your blood sugar level rises to 120 mg/100 mL, which physiological response would you expect to occur in order to maintain homeostasis?
A
The kidneys reabsorb more glucose from the filtrate.
B
The liver converts glycogen to glucose and releases it into the bloodstream.
C
The pancreas releases glucagon to increase blood glucose levels.
D
The pancreas releases insulin to promote glucose uptake by cells.
Verified step by step guidance

Understand the concept of homeostasis: Homeostasis is the process by which the body maintains a stable internal environment. In this case, the body regulates blood sugar levels to keep them within a normal range.
Identify the physiological response to high blood sugar: When blood sugar levels rise above the normal range (e.g., 120 mg/100 mL), the body needs to lower the glucose concentration in the bloodstream to restore balance.
Recognize the role of insulin: The pancreas releases insulin, a hormone that facilitates the uptake of glucose by cells, particularly muscle and fat cells, and promotes the storage of glucose as glycogen in the liver. This helps reduce blood sugar levels.
Eliminate incorrect options: The kidneys reabsorbing more glucose, the liver converting glycogen to glucose, and the pancreas releasing glucagon are responses associated with low blood sugar levels, not high blood sugar levels.
Conclude the correct response: The correct physiological response to high blood sugar is the release of insulin by the pancreas to promote glucose uptake by cells and restore homeostasis.
