Final answer:
LDL-cholesterol carries cholesterol from the liver to tissues and can deposit it in the arteries, contributing to plaque formation, which is why it's considered "bad cholesterol." HDL-cholesterol, on the other hand, is "good cholesterol" that transports cholesterol from tissues back to the liver for disposal.
Step-by-step explanation:
The statement that LDL-cholesterol picks up cholesterol from the arteries and moves it to the liver for disposal is false. LDL, or low-density lipoproteins, carry cholesterol from the liver to cells throughout the body and can deposit excess cholesterol in arterial walls, leading to plaque formation and atherosclerosis. This is why LDL is often referred to as "bad cholesterol." On the other hand, HDL-cholesterol (high-density lipoproteins), which is known as "good cholesterol," is responsible for transporting cholesterol from the tissues back to the liver where it gets reused or excreted.
