Blood Glucose and Insulin Regulation

Front

Which organ is primarily responsible for detecting a rise in blood glucose concentration and releasing insulin?

Back

Pancreas

Front

The main role of insulin is to increase the permeability of cell membranes (especially muscle and fat cells) to allow glucose to enter and be used or stored. True or False?

Back

True

Front

What is the storage molecule for excess glucose in the liver and muscle cells?

Back

Glycogen

Front

Describe the immediate effect that insulin has on the liver.

Back

It promotes the uptake of glucose and its conversion into glycogen for storage.

Front

In the context of blood glucose control, which statement best describes the principle of negative feedback?

Back

A change in blood glucose levels triggers a response that opposes the initial change, bringing the level back to the set point.

Front

A key difference between Type I and Type II diabetes is that in Type I, the body's cells become resistant to the effects of insulin, whereas in Type II, the body stops producing insulin. True or False?

Back

False

Front

Which is a common symptom of untreated or poorly controlled diabetes, regardless of the type?

Back

Excessive thirst and frequent urination

Front

Type I diabetes is often treated with daily insulin injections or an insulin pump because:

Back

The patient's pancreas fails to produce sufficient insulin.

Front

The consequences of consistently failing to regulate blood glucose effectively can include damage to which of the following body systems?

Back

Central nervous system, eyes, and kidneys

Front

Which of the following statements accurately compares the primary cause and treatment approach for Type I and Type II diabetes?

Back

Type I is caused by an autoimmune response destroying insulin-producing cells and is treated with insulin replacement; Type II is often linked to obesity/genetics causing insulin resistance and is managed initially with diet/exercise and possibly medication.
