A young man in his 20s has a heart attack and is rushed to the hospital. Blood is drawn, and his cholesterol level is tested and found to be very high. The doctor tells him that he has a genetic condition in which he is unable to effectively remove LDL particles containing cholesterol from his blood and into his cells. Which cellular process is not functioning normally? a. channel-mediated facilitated diffusion b. receptor-mediated endocytosis c. exocytosis d. simple diffusion?
