How regions of phospholipids are arranged in the cell membrane?

The phospholipids of a cell membrane are arranged in a double layer called the lipid bilayer. The hydrophilic phosphate heads are always arranged so that they are near water. Watery fluids are found both inside a cell (intracellular fluid) and outside a cell (extracellular fluid).

Which of the following correctly describes how phospholipids are arranged in a plasma membrane?

So, the correct answer is 'Two layers of phospholipids where the outer layer has the hydrophilic heads facing toward the outside of the cell and the inner layer have the hydrophobic tails facing toward the inside of the cell.

How are phospholipids arranged in the cell membrane quizlet?

The phospholipid is arranged in a bilayer with the hydrophobic tail facing inside and the hydrophilic head facing outside.

What is the structure of a phospholipid in the cell membrane?

The structure of a phospholipid molecule contains two hydrophobic tails of fatty acids and one hydrophilic head of phosphate moiety, jointed together by an alcohol or glycerol molecule [90]. Due to this structural arrangement, PLs form lipid bilayers and are a key component of all the cell membranes.
