Question
Which of the following is false about the phospholipids in the cell membrane?Phospholipids of the bilayer have one fatty acid and a phosphate group.Phospholipids of the bilayer have two fatty acids and a phosphate group.Phospholipids of the bilayer always have hydrophilic phosphate heads.Phospholipids of the bilayer always have a hydrophobic tail.
Solution
The false statement about the phospholipids in the cell membrane is: "Phospholipids of the bilayer have one fatty acid and a phosphate group."
In reality, phospholipids in the cell membrane are composed of two fatty acid chains and a phosphate group. The fatty acid chains are hydrophobic (water-repelling), while the phosphate group is hydrophilic (water-attracting). This structure allows the cell membrane to form a barrier between the inside and outside of the cell.
