Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of lipid forms the primary structure of the cell membrane?
A
triglycerides
B
wax
C
cholesterol
D
phospholipid
Explanation: 

Detailed explanation-1: -The fundamental building blocks of all cell membranes are phospholipids, which are amphipathic molecules, consisting of two hydrophobic fatty acid chains linked to a phosphate-containing hydrophilic head group (see Figure 2.7).

Detailed explanation-2: -Within a cell membrane, the primary type of lipid used is the phospholipid. Phospholipids form the majority of our cell membranes and are made from two primary parts. These parts are the hydrophilic phosphate head and the hydrophobic fatty acid tail.

Detailed explanation-3: -The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments. In the case of the plasma membrane, these compartments are the inside and the outside of the cell.
