Question

Different processes have an impact on the body's cholesterol levels. Cholesterol can be synthesized in cells or absorbed from the diet, but which process has the greatest impact on the loss of cholesterol? a. Cholesterol is converted into steroid hormones in particular the sex hormones testosterone and oestradiol, which are excreted through urine. O b. During fasting, cholesterol is oxidized to acetyl-CoA in tissues, including the brain that cannot oxidize fatty acids. c. Certain cell types such as enterocytes have a very short lifespan. Cholesterol is dropped when enterocytes in the gut die and are excreted in the stool. d. Cholesterol is absorbed from the blood as oxidized LDL particles of macrophages and removed by lysosomal degradation. e. Cholesterol is excreted via the bile to the intestinal lumen and reabsorbed into the enterohepatic circulatory system. Part of the cholesterol and bile salts are thereby lost in the stool.
