- Order following for rate of diffusion through a synthetic lipid bilayer. Explain your order. Cl-, N2, alanine, tRNA, ribose, H2OWhat major type of molecule contributes to the formation of the cell membrane and what biochemical properties of this molecule promotes the formation of the membrane? What effect allows this type of molecule to come together to form a bilayer and explain how the effect works? A▾ B I I e 2 2Although lipids are largely responsible for providing and maintaining the structure of the Ven membrane, most of the membrane's functions are due to the proteins that are present in it. Membrane proteins can be classified as integral or peripheral, depending on how they are Posiioned in the phospholipid bilaver. Based on figure 12, differentiate integral and peripheral proteins. Write your answer on the table below. Table 18: Difference Between Integral and Peripheral Membrane Proteins Integral Proteins Peripheral Proteins
