Phospholipids

Question

Phospholipids
A) are found in cell membranes.
B) are used as an energy source by cells.
C) can be modified to form cholesterol.
D) are involved in the process of inflammation.
E) are found inside organelles.

Accepted Answer

Phospholipids are a major component of cell membranes, forming a lipid bilayer that separates the interior of the cell from its external environment. They have hydrophilic (water-loving) heads and hydrophobic (water-fearing) tails that orient themselves to create the membrane structure. While phospholipids can be broken down for energy, they are not a primary energy source for cells. Phospholipids are not involved in the process of inflammation and cannot be directly modified to form cholesterol. While phospholipids may be present in some organelles, they are not exclusively found inside organelles.
