The liver can absorb cholesterol from peripheral tissues via the blood. This process is known as reverse cholesterol transport. Which is considered to be the quantitatively most significant way in which liver hepatocytes take up cholesterol from human peripheral tissue? a. Cholesterol is amphipathic and circulates in the blood freely or bound to globulins, from which it is primarily taken up by the hepatocytes by direct incorporation into the plasma membrane. b. Cholesterol is primarily taken up by endocytosis of...
