It was discovered that a fraction of membrane proteins can be removed by immersing a membrane in an aqueous salt solution, whereas the remaining fraction of proteins can only be removed by immersing the membrane in a detergen solution or organic solvent which dissolves lipids. Which fraction contains the peripheral proteins and which fraction contains the integral proteins and why? What does this experiment say about the way peripheral and integral proteins are bound to membranes?

Solution

Dynamically unstable and are assembled by centrosome : C) microfilament associated proteins.

Stable molecular structures assembled by basal bodies : B) actin filaments.
