Question
Which of the following Incorrectly describes the Phospholipid bilayer?Proteins embedded in the bilayer facilitates transport of substances.Phospholipids associates to form two layersThe hydrophobic tails are pointed outward.The hydrophobic tails are pointed inward.
Solution
The statement that incorrectly describes the phospholipid bilayer is: "The hydrophobic tails are pointed outward."
In a phospholipid bilayer, the hydrophobic (water-fearing) tails are pointed inward towards each other, while the hydrophilic (water-loving) heads are pointed outward towards the water environment. This arrangement allows the bilayer to form a barrier between the inside and outside of the cell, or between different compartments within the cell.
