Question 1 of 5
Which gastric enzyme present in infants coagulates milk?
Correct Answer: D
Rationale: The correct answer is D, rennin. Rennin is the enzyme in infants responsible for coagulating milk, which aids in the digestion process.
Choice A, casein, is a milk protein and not an enzyme.
Choices B and C, pepsinogen and trypsin, are digestive enzymes but are not specifically involved in coagulating milk in infants.
Question 2 of 5
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 3 of 5
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.
Question 4 of 5
Which option below is an example of a meal or snack that contains complementary proteins?
Correct Answer: B
Rationale: The correct answer is B, a peanut butter sandwich. A peanut butter sandwich combines grains from the bread and proteins from the nuts in the peanut butter, providing complementary proteins. This combination offers all essential amino acids.
Choices A, C, and D do not contain complementary proteins as they lack the combination of different protein sources necessary to provide a complete amino acid profile.
Question 5 of 5
Which lipoprotein increases the risk of cardiovascular disease?
Correct Answer: A
Rationale: The correct answer is A: Low-density lipoprotein (LDL). LDL is often referred to as 'bad cholesterol' because it can lead to plaque buildup in arteries, increasing the risk of cardiovascular disease. High-density lipoprotein (HDL) is considered 'good cholesterol' as it helps remove LDL from the arteries, reducing the risk of cardiovascular issues. Very low-density lipoprotein (VLDL) and chylomicrons are also lipoproteins that transport fats in the bloodstream, but they are not as strongly associated with an increased risk of cardiovascular disease as LDL.
