How is cholesterol stored in a steroidogenic cell?
Homework Answers
Within steroidogenic cell, cholesterol is stored in LIPID DROPLETS(lipid bodies) in the form of cholesterol esters, and the mobilization of these stored cholesterol esters is the preferred source of cholesterol for steroidogenesis upon hormone stimulation.

Cholesterol is an essential ingredient of cell membranes. In atherosclerosis, it accumulates in plaque on artery walls and gallstones can be nearly pure cholesterol. About 85% of the roughly 150 g of cholesterol in a healthy human body is found in cell membranes. The structure below is the enantiomer of natural cholesterol Using the structure and image below, determine the conformation of each of the designated substituents (Use the carbon atom numbering from the image on the left.) CH3 На...

Depletion of cholesterol in the cell membrane using a drug (mevastatin) has been associated with apoptosis in cancer cells. a. What effect would cholesterol depletion have on the integrity of lipid rafts in the membrane? b. Researchers found that FAS death receptor was activated in cholesterol depleted cancer cells. Explain how activation of this receptor activates killer caspases. c. When a caspase is converted from its inactive to its active form there are changes in the primary and tertiary structure...

The role of very low density lipoproteins is 1. Scavenging the cholesterol from cell membranes 2. Transporting of lipids from liver to tissues 3. Transporting of cholesterol esters to the liver 4. Both A and B are correct 5. All of the above are correct

Cancer cells typically have less cholesterol and more phospholipid in their cell membranes. This phenotype is also associated with resistance to apoptosis. The FAS death receptor is localized to lipid rafts. Using this information to explain why increased phospholipid and increased cholesterol could inhibit the initiation of apoptosis. Rubric (2): Plausible link between increased change in membrane composition, effect on lipid raft formation and lack of FAS receptor activation.

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...

If a cell does not have mitochondria, it cannot harvest the entire energy stored in a molecule of glucose? A)True B)False Phosphofructokinase is an enzyme that is important for the breakdown of the glucose molecule to generate ATP. In regards to that, when the ATP levels are high, the phosphofructokinase is inhibited. What do you expect to happen to the enzyme when the levels of ATP within the cell drop? 1.The enzyme will be activated. 2.The enzyme will be deactivated....
