Which component of the cell membrane is primarily responsible for its fluidity?

Which component of the cell membrane is primarily responsible for its fluidity?

Step 1: Understand that the cell membrane is made up of a double layer of phospholipids.
Step 2: Know that phospholipids have a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tails.
Step 3: Realize that the phospholipids can move around, which gives the membrane its fluid nature.
Step 4: Learn that cholesterol molecules are found within the phospholipid bilayer.
Step 5: Understand that cholesterol helps to stabilize the membrane and prevents it from becoming too rigid or too fluid.
Step 6: Conclude that cholesterol is the component that primarily helps maintain the fluidity of the cell membrane.
