Question 1 of 9

Which of the following enzymes is found in pancreatic secretions?

Correct Answer: C

Rationale: Chymotrypsin is an enzyme found in pancreatic secretions that plays a role in protein digestion. Rennin is primarily found in the stomach and is involved in milk digestion. Pepsin is also a stomach enzyme that aids in protein breakdown. Casein is a protein found in milk, not an enzyme involved in pancreatic secretions. Therefore, the correct answer is Chymotrypsin.

Question 2 of 9

Which lipoprotein carries fat from a meal just consumed to the liver?

Correct Answer: C

Rationale: Chylomicrons are the lipoproteins responsible for transporting dietary fat from the intestines to various tissues, including the liver. VLDL carries lipids synthesized in the liver, LDL transports cholesterol to tissues, and HDL helps transport cholesterol away from tissues to the liver for excretion. Therefore, in the context of carrying fat from a meal just consumed to the liver, chylomicrons are the correct choice.

Question 3 of 9

How many amino acids are considered indispensable or essential?

Correct Answer: A

Rationale: The correct answer is A: 9. Nine amino acids are considered essential or indispensable because they cannot be synthesized by the body and must be obtained through the diet. These amino acids include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices B, C, and D are incorrect as the number of essential amino acids is specifically 9, as they are crucial for various bodily functions.

Question 4 of 9

What can excessive intakes of dietary protein do?

Correct Answer: B

Rationale: Excessive intake of dietary protein can lead to impaired kidney function over time. Excessive protein consumption can put a strain on the kidneys as they work to eliminate the byproducts of protein metabolism. This can potentially lead to kidney damage. Choices A, C, and D are incorrect. Excessive protein intake is not directly linked to causing vitamin deficiencies, increasing weight loss, or decreasing the production of indispensable amino acids.

Question 5 of 9

Which type of carbohydrate helps maintain normal blood glucose levels during fasting periods?

Correct Answer: D

Rationale: The correct answer is glycogen. Glycogen is a type of carbohydrate stored in the body that is broken down into glucose to help maintain blood glucose levels during fasting periods. Glucose (choice A) is the simplest form of sugar and is a product of carbohydrate digestion, not the stored form like glycogen. Galactose (choice B) is a monosaccharide found in dairy products. Dextrins (choice C) are intermediate products of starch digestion and not directly involved in maintaining blood glucose levels during fasting.

Question 6 of 9

What is the maximum recommended daily intake of cholesterol?

Correct Answer: C

Rationale: The correct answer is C: 300 mg. The recommended maximum daily intake of cholesterol is 300 mg to reduce the risk of heart disease. Option A (100 mg) is too low, which may not provide enough cholesterol for normal bodily functions. Option B (200 mg) is also below the recommended limit. Option D (400 mg) exceeds the recommended daily intake, increasing the risk of heart disease.

What are dextrins?

Correct Answer: A

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Question 9 of 9

Which compound is necessary for emulsification of fat in the body?

Correct Answer: A

Rationale: Bile salts are essential for emulsifying fats in the body. They break down fats into smaller droplets, increasing the surface area for enzymes to work on during digestion. Cholecystokinin is a hormone that stimulates the release of bile and pancreatic enzymes, but it is not directly involved in emulsification. Chyme is the semi-fluid mass of partly digested food that moves from the stomach to the small intestine and does not play a role in emulsifying fats. Trypsin is an enzyme produced by the pancreas that acts on proteins, not fats.
