What happens to blood glucose levels after a meal?
Increase
Which hormone raises blood glucose levels by converting stored glycogen to glucose?
Glucagon
What is the role of insulin in blood glucose regulation?
Promotes the conversion of glucose to glycogen for storage
What happens when blood glucose levels decrease?
The pancreas secretes glucagon to increase blood glucose levels
How does glucagon affect blood glucose levels?
Promotes the conversion of stored glycogen to glucose
What are common symptoms of diabetes mellitus?
Increased thirst and frequent urination
What characterizes Type 1 Diabetes?
Requires lifelong insulin injections and dietary management
What is the main focus of treatment for Type 2 Diabetes?
Lifestyle modifications including diet, exercise, and medication
How does insulin resistance affect blood glucose levels?
Results in ineffective glucose uptake by cells, raising blood glucose levels
What is the function of glycogen in the body?
Provides immediate energy in the form of glucose storage
What term refers to the process by which living organisms maintain stable internal conditions?
Homeostasis
Which hormone helps raise blood glucose levels by converting stored glycogen to glucose?
Glucagon
What is the main function of glucagon in blood glucose regulation?
Raise blood glucose levels
Which of the following hormones is responsible for lowering blood glucose levels?
Insulin
What is the stored form of glucose in the liver and muscles called?
Glycogen
How do negative feedback mechanisms contribute to homeostasis?
By detecting and counteracting deviations
Why is it crucial for blood glucose levels to be carefully regulated?
To ensure adequate energy supply
In diabetes mellitus, which of the following symptoms is commonly associated with high blood glucose levels?
Excessive thirst
Which type of diabetes is typically managed with insulin injections and dietary adjustments?
Type 1 Diabetes
Insulin resistance, a common feature of Type 2 Diabetes, is primarily caused by:
Poor response to insulin
Which hormone plays a key role in converting stored glycogen into glucose to raise blood glucose levels?
Glucagon
What is the main metabolic difference between Type 1 and Type 2 Diabetes?
Insulin production
What is the primary outcome of cells taking up glucose when stimulated by insulin?
Conversion to glycogen
Which of the following lifestyle factors is most likely to contribute to the development of Type 2 Diabetes?
Sedentary behavior
What is the function of glucagon in blood glucose regulation when compared to insulin?
Converts glycogen to glucose
Which hormone is responsible for converting stored glycogen to glucose to raise blood glucose levels?
Insulin
What is the primary mechanism by which negative feedback mechanisms contribute to homeostasis?
Detecting and counteracting deviations from optimal conditions
Which hormone plays a key role in converting glucose to glycogen, thus lowering blood glucose levels?
Insulin
What is the primary function of glucagon in blood glucose regulation?
Raising blood glucose levels
Which hormone is critical in converting stored glycogen into glucose to raise blood glucose levels?
Glucagon
What is the stored form of glucose in the liver and muscles?
Glycogen
What hormone is produced by the pancreas to lower blood glucose levels by converting glucose to glycogen?
Insulin
What is the key metabolic difference between Type 1 and Type 2 Diabetes?
Type 1 Diabetes involves loss of insulin-producing cells, while Type 2 Diabetes involves ineffective insulin response due to poor lifestyle choices.
What role does glucagon play in blood glucose regulation compared to insulin?
Glucagon lowers blood glucose levels by converting glycogen into glucose, while insulin raises blood glucose levels by promoting glucose storage.
How do insulin resistance and poor lifestyle choices contribute to the development of Type 2 Diabetes?
Insulin resistance hinders glucose uptake by cells, while poor lifestyle choices impair insulin production.
Which hormone raises blood glucose levels by converting stored glycogen to glucose?
Glucagon
What is the primary outcome of cells taking up glucose when stimulated by insulin?
Lowered blood glucose levels
How does glucagon affect blood glucose levels?
By converting glycogen into glucose
Which lifestyle factor is most likely to contribute to the development of Type 2 Diabetes?
Sedentary behavior
Why is maintaining stable blood glucose levels crucial?
To provide energy for cellular functions
