Cholesterol, triglycerides, and phospholipids travel between the liver and peripheral tissues ...

Correct Answer: 1
Rationale 1: Apoproteins are specific for cholesterol, triglycerides, and phospholipids, and they act as carrier molecules for transporting these lipids through the blood.
Rationale 2: Lipid molecules are not soluble in plasma and so require protein binding for transport.
Rationale 3: Albumin is the most common plasma protein, but it is not specific as a carrier for cholesterol, triglycerides, and phospholipids.
Rationale 4: Lipoprotein molecules that combine lipids with a carrier protein contain different amounts of cholesterol, triglycerides, and phospholipids.
