Biology CLEP Prep Practice Exam

What are the major components of a lipoprotein?

1. Fatty acids, proteins, and carbohydrates

2. Cholesterol, proteins, and phospholipids

3. Phospholipids, proteins, and lipids

4. Lipids, carbohydrates, and cholesterol

The correct answer is: Cholesterol, proteins, and phospholipids

A lipoprotein is a complex molecule that transports lipids (fats) in our bloodstream. While all the components listed in the choices can be found in a lipoprotein, the major components are cholesterol, proteins, and phospholipids. Fatty acids and carbohydrates may also be present in smaller amounts, but they are not considered major components. Phospholipids, proteins, and lipids together make up the structure of the lipoprotein, while cholesterol is the main lipid carried by the lipoprotein. Therefore, B is the correct answer.
