Infections are common in people who have inadequate protein intake because of an insufficient quantity of:

  • A. insulin.
  • B. lipoprotein.
  • C. antibodies.
  • D. albumin.
Correct Answer: C

Rationale: Inadequate protein intake can lead to a decrease in antibody production, making individuals more susceptible to infections. Insulin (Choice A) is a hormone involved in regulating blood sugar levels, not related to protein intake. Lipoprotein (Choice B) is a type of lipid-protein complex involved in lipid transport, not directly related to antibody production. Albumin (Choice D) is a protein that helps maintain oncotic pressure and carries various substances in the blood, but it is not primarily responsible for fighting infections like antibodies.

How is the enzyme trypsin activated?

  • A. By zymogen.
  • B. By bile.
  • C. By gastrin.
  • D. By enterokinase.
Correct Answer: D

Rationale: The correct answer is D: By enterokinase. Trypsin is activated by enterokinase, an enzyme secreted by the small intestine. Enterokinase plays a crucial role in converting trypsinogen into its active form, trypsin. Choices A, B, and C are incorrect because trypsin is specifically activated by enterokinase, not by zymogen, bile, or gastrin.

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

  • A. Bile salts
  • B. Cholecystokinin
  • C. Chyme
  • D. Trypsin
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.

What is the recommended dietary intake of protein for adults?

  • A. 0.5 g/kg.
  • B. 0.8 g/kg.
  • C. 1.0 g/kg.
  • D. 1.5 g/kg.
Correct Answer: B

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

Which of the following enzymes is found in pancreatic secretions?

  • A. Rennin
  • B. Pepsin
  • C. Chymotrypsin
  • D. Casein
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.

What is the maximum recommended daily intake of cholesterol?

  • A. 100 mg.
  • B. 200 mg.
  • C. 300 mg.
  • D. 400 mg.
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.
