18 Questions
What is the primary function of insulin in blood glucose regulation?
Sending a signal to store excess glucose
What is the result of glucagon's action on the liver?
The breakdown of glycogen into glucose
What is the purpose of homeostatic control in blood glucose regulation?
To maintain a stable blood glucose level
How does the body respond to low blood glucose levels?
By releasing glucagon into the bloodstream
What is an example of negative feedback in blood glucose regulation?
The release of insulin in response to high blood glucose levels
What is the fate of excess glucose in the blood?
It is stored as glycogen in the liver and muscles
What is the primary function of insulin in the body?
To decrease blood glucose levels
What happens when glucagon is secreted into the blood?
The liver converts glycogen into glucose
What is the target range for blood glucose levels in an adult?
60-100 mg/dL
What is the primary function of insulin in glucose regulation?
To store glucose in the liver and muscles
What happens to excess glucose in the liver?
It is converted into glycogen
What is the role of glucagon in glucose homeostasis?
To stimulate glycogen breakdown and glucose release
What is the negative feedback mechanism that helps to regulate blood glucose levels?
Insulin decreases blood glucose levels, which decreases glucagon secretion
What type of feedback mechanism is involved in glucose level regulation?
Negative feedback
What is the primary organ responsible for storing glycogen?
Liver
What is the ultimate goal of homeostatic control in glucose regulation?
To maintain steady internal glucose levels
What is the primary site of glucose storage in the body?
Liver
What is the learning competency related to glucose regulation?
Explain how some organisms maintain steady internal conditions
Test your understanding of homeostatic control through negative feedback, focusing on the regulation of blood glucose levels and the role of hormones like insulin and glucagon.
