Which hormone is responsible for stimulating the gallbladder to contract and release bile?

  • A. gastric lipase
  • B. cholecystokinin
  • C. vitamin D
  • D. enterokinin
Correct Answer: B

Rationale: Cholecystokinin (CCK) is the correct answer. It is the hormone responsible for stimulating the gallbladder to contract and release bile to aid in fat digestion. Gastric lipase (Choice A) is an enzyme that breaks down fats in the stomach, not a hormone involved in gallbladder function. Vitamin D (Choice C) is important for calcium absorption and bone health, but it is not directly related to gallbladder function. Enterokinin (Choice D) is a peptide hormone that affects smooth muscle contractions in the gastrointestinal tract, but it is not specifically responsible for stimulating the gallbladder to release bile.

Which of the following is an example of a plasma protein?

  • A. Collagen.
  • B. Myosin.
  • C. Albumin.
  • D. Phospholipid.
Correct Answer: C

Rationale: The correct answer is C, albumin. Albumin is a plasma protein that plays a crucial role in maintaining fluid balance in the blood. Collagen (choice A) is a structural protein found in connective tissues, not a plasma protein. Myosin (choice B) is a protein involved in muscle contraction, not found in the blood plasma. Phospholipid (choice D) is a type of lipid molecule, not a protein present in plasma.

Which of the following is an example of a complete protein?

  • A. Milk
  • B. Soy
  • C. Sesame seeds
  • D. Sweet potato
Correct Answer: A

Rationale: The correct answer is A, Milk. Milk is considered a complete protein as it contains all the essential amino acids required by the body. Soy (choice B) is also a complete protein, containing all essential amino acids. Sesame seeds (choice C) and sweet potato (choice D) are not complete proteins as they lack one or more essential amino acids needed by the body.

Which lipoprotein increases the risk of cardiovascular disease?

  • A. Low-density lipoprotein (LDL)
  • B. High-density lipoprotein (HDL)
  • C. Very low-density lipoprotein (VLDL)
  • D. Chylomicrons
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.

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.
