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

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

Step 1: Understand that the cell membrane is made up of different components, including phospholipids and cholesterol.
Step 2: Know that phospholipids are the main building blocks of the cell membrane and they form a double layer.
Step 3: Learn that cholesterol is a type of fat molecule that can fit between the phospholipids in the membrane.
Step 4: Realize that cholesterol helps to keep the membrane flexible, or fluid, especially when temperatures change.
Step 5: Conclude that cholesterol is the component that primarily helps maintain the fluidity of the cell membrane.
