Detailed explanation-1: -Lipid-that is, fatty-molecules constitute about 50% of the mass of most animal cell membranes, nearly all of the remainder being protein. There are approximately 5 × 106 lipid molecules in a 1 m × 1 m area of lipid bilayer, or about 109 lipid molecules in the plasma membrane of a small animal cell.

Detailed explanation-2: -As structural components of the plasma membrane, lipids are responsible for contributing to membrane tension, rigidity, and overall shape. After an injury, the biophysical properties of the plasma membrane, and the individual lipids themselves, are altered, eliciting changes to membrane rigidity and fluidity.
