Based on the text, what is the primary difference in function between low-density lipoprotein LDL and high-density lipoprotein HDL ?

  • A: LDL scavenges excess cholesterol, while HDL delivers cholesterol to cells.
  • B: LDL delivers cholesterol to cells for membrane production, while HDL scavenges excess cholesterol.
  • C: Both LDL and HDL are types of fatty deposits that harden arteries.
  • D: LDL causes angina pectoris, while HDL prevents strokes.

Explanation

The text clearly defines their roles: 'low-density lipoprotein LDL —delivers cholesterol to cells for membrane production. Another type—high-density lipoprotein HDL —scavenges excess cholesterol.'
