Answer to Question 1

Correct Answer: 2
Rationale: HDL is considered good because it carries cholesterol away from tissues and to the liver for metabolism and excretion. High levels of HDL are useful for lowering the risk of heart disease. Triglycerides are not lipoproteins; they make up lipoproteins. LDL does contain the most cholesterol, but it does not carry it to the liver for excretion. Through several steps, VLDL is converted to LDL.

Answer to Question 2

Correct Answer: 3
Rationale: Cholesterol is a steroid, and is known for its role in promoting atherosclerosis. There are three types of lipids important for humans: triglycerides, phospholipids, and steroids. Lecithins are a phospholipid.
