GLP-1 Quiz Questions and Answers: 25 Multiple-Choice Questions

Section 1: GLP-1 Basics and How It Works

Question 1: What Does GLP-1 Stand For?

A. Glucose Lipid Protein-1
B. Glucagon-Like Peptide-1
C. General Lipid Peptide-1
D. Glucose-Lowering Protein-1

Correct Answer: B. Glucagon-Like Peptide-1

Explanation: GLP-1 is a naturally occurring hormone released primarily by specialized intestinal cells after food consumption. It helps regulate blood sugar, appetite, and digestion. GLP-1 receptor agonist medications reproduce important effects of this hormone, making them useful in certain diabetes and weight management treatments.

Question 2: What Is the Primary Function of GLP-1?

A. Increasing blood pressure
B. Stimulating hunger
C. Helping regulate blood sugar and appetite
D. Preventing nutrient absorption completely

Correct Answer: C. Helping regulate blood sugar and appetite

Explanation: GLP-1 supports glucose regulation by stimulating insulin release when blood sugar is elevated and reducing inappropriate glucagon secretion. It also influences digestive activity and communicates fullness signals to the brain, helping regulate food intake.

Question 3: Where Is Natural GLP-1 Mainly Produced?

A. Kidneys
B. Lungs
C. Intestines
D. Bones

Correct Answer: C. Intestines

Explanation: GLP-1 is primarily released by enteroendocrine L cells in the digestive tract. Its secretion increases after meals, allowing the body to coordinate insulin production, glucose management, and appetite-related signals.

Question 4: How Do GLP-1 Medications Support Weight Loss?

A. By permanently eliminating body fat cells
B. By reducing appetite and increasing fullness
C. By preventing all carbohydrates from being absorbed
D. By replacing the need for physical activity

Correct Answer: B. By reducing appetite and increasing fullness

Explanation: GLP-1 receptor agonists activate pathways that influence hunger and fullness. They also slow stomach emptying, particularly during early treatment. Together, these effects can help reduce calorie intake and support significant weight reduction when combined with appropriate lifestyle changes.

The World Health Organization identifies appetite regulation, glucose control, and slower digestion as central mechanisms of GLP-1 therapy.

Question 5: Which Organ Releases Insulin in Response to GLP-1?

A. Liver
B. Pancreas
C. Stomach
D. Gallbladder

Correct Answer: B. Pancreas

Explanation: GLP-1 stimulates insulin secretion from pancreatic beta cells when blood glucose is elevated. This glucose-dependent action helps lower blood sugar and is one reason GLP-1 medications are widely used in type 2 diabetes management.
